Add graphics adapter resolution auto-detection into Easy2Boot

You may want to display your E2B menu in the highest/best resolution possible.
For instance, some odd systems may not support 800x600 mode.

I always advise you to use the most common display resolution so that the menu will appear correctly on all systems. However, you can arrange E2B so that it will cope with a variety of different systems.

You will need a range of wallpaper bitmaps for each resolution (though in some cases the largest bitmap may work for smaller resolution displays).

Auto-Detect highest resolution and use correct wallpaper

The code below can be used in a \_ISO\MyE2B.cfg menu to auto-detect the highest resolution available and then set the graphicsmode and wallpaper for that resolution. 

Note that the position of the menu will remain the same (unless you also add extra code - e.g. if "%GMODE%"=="1024 768 24" set rstart=5) and so will the text colours, etc. See the Sample MyE2B.cfg file for an example.

So each wallpaper bitmap should be similar in colour and content because the menu position and text colours will not change.

# allow vbeprobe command to output text
debug 1
# list all available BIOS graphics adpapter modes
vbeprobe > (md)0x220+5
# turn off text output for future commands
debug off
# look for 640, 800 and 1024 modes - be careful to only use x24 or x32 modes for full colour bitmaps
cat --locate=", 640x480x24"  (md)0x220+5 > nul && set GMODE=640 480 24 && set MYWBMPGZ=/_ISO/nice640.bmp.gz
cat --locate=", 800x600x24"  (md)0x220+5 > nul && set GMODE=800 600 24 && set MYWBMPGZ=/_ISO/nice800.bmp.gz
cat --locate=", 1024x768x24" (md)0x220+5 > nul && set GMODE=1024 768 24 && set MYWBMPGZ=/_ISO/nice1024.bmp.gz

# DELETE THESE TWO LINES ONCE IT IS WORKING
cat (md)0x220+5
echo GMODE=%GMODE%  MYWBMPGZ=%MYWBMPGZ% && pause

Add a Change Language menu entry to Easy2Boot

This Change_Language.mnu file will be in the Sample mnu Files folder in v1.55 and later versions.
It allows the user to temporarily change the language strings (until reboot).

Using this and the Change_Theme.mnu, you can demo E2B to your colleagues!

You can modify it by adding or removing languages or write it in a different language other than English (save the file as UTF-8 if using non ASCII characters).

title Change the E2B Language\n Change the standard E2B menus to a different language
echo
echo Change Language
echo -e ===============
echo
echo Only the standard E2B menu entries, headings and some prompts will change.
echo  Note: This does not change the E2B Header or the Footer help text
echo
echo Please choose a language...

if "%ask%"=="4" set LANG=PORTU_BRAZIL
if "%ask%"=="5" set LANG=SIMP_CHINESE
if "%ask%"=="6" set LANG=TRAD_CHINESE

configfile /%grub%/Menu.lst



Note that you can set a default language in your \_ISO\MyE2B.cfg file, but it must be set using a line like this - otherwise the Change Language menu will not work:

if "%LANG%"=="" set LANG=SPANISH



Add a 'Change Theme' menu to Easy2Boot

It is fairly easy to add a .mnu file which allows the user to choose a different background wallpaper:

title Change Wallpaper\n Choose a new E2B menu background
set CHOSEN=
call /%grub%/pickafile.g4b /_ISO .gz
if "%CHOSEN%"=="" configfile (md)0xa000+0x50
clear
splashimage /_ISO/%CHOSEN%
configfile (md)0xa000+0x50

The .gz files must contain a bitmap of exactly the correct resolution size - e.g. 800x600  (801x588 will NOT work!). The actual existing menu text and border positions, etc. is not changed however, so the images that you use should work with the same settings used by E2B as the default (or as used in your \_ISO\MyE2B.cfg file). So you will need to pick your images carefully (plain colour ones work best).


Today, devdevadev asked me if he could have a menu to switch between themes. You can use this to demo E2B, e.g. switch backgrounds, language, font, colours, etc.

A menu would prompt you to pick a .cfg file as shown below:



Here is the .mnu file that I came up with:

# Place all MyE2B.cfg and wallpaper files in \_ISO\mythemes and all rename .cfg files (amd any message GFXBoot file if more than one)
# Edit each \_ISO\mythemes\xx.cfg file so background or GFX has correct path
# e.g. set MYWBMPGZ=/_ISO/mythemes/stripedflat.bmp.gz  OR set GFX=mythemes/message  (note: no /_ISO/ for GFX path)
# Rename \_ISO\Sample_MyE2B.cfg to \_ISO\MyE2B.cfg (must be >1KB and larger than largest xxx.cfg file)
# For the default E2B theme, make a \_ISO\mythemes\Default_Theme.cfg file with just !BAT on the first line
# \_ISO\MyE2B.cfg file must be contiguous due to bug in grub4dos!

title Change Theme\n Choose a new E2B Theme

if not exist /_ISO/MyE2B.cfg echo ERROR: Please create a large \_ISO\MyE2B.cfg file && pause && configfile (md)0xa000+0x50
set CHOSEN=

if exist ()/_ISO/mythemes/%CHOSEN% dd if=()/_ISO/mythemes/%CHOSEN% of=()/_ISO/MyE2B.cfg > nul
if exist ()/_ISO/mythemes/%CHOSEN% chainloader /grldr
boot

I tested this using these files in the E2B \_ISO\mythemes folder :


The 'graphicsmode 3switch is required only if you use GFX Boot menus such as the sample Jolene_GFX.mnu. You can delete it if you don't have any GFXBoot .cfg files. If you do use GFXBoot menus, you will also need to copy all the \_ISO\docs\GFXSubMenu Files .mnu files into \_ISO\MAINMENU or else some menu entries will be missing from the GFXBoot menu when selected (this applies to any GFXBoot menu).

Both .mnu files will be in the Sample mnu Files folder in v1.55 of E2B and I will also put them in the Alternate Download area for a while too.

v1.55 will have the mythemes folder and a selection of .cfg files to choose from. You will just need to copy a $Default E2B Menu.cfg file to \_ISO\MyE2B.cfg and the .mnu file to \_ISO\MAINMENU.

Notes: due to a bug I just discovered in grub4dos, make sure you run WinContig on the E2B drive to make all files contiguous. It seems there is a problem with grub4dos and NTFS volumes if this is not done (if the target file is fragmented, then only the first 8096 bytes are actually copied when using dd on some files!).

And due to another bug, the full path for the bitmap file needs to be kept shorter than approx 64 characters as the splashimage command cannot handle long pathnames!

Easy2Boot v1.54 released


Improvements over 1.53 are:
  1. Bugfix for forcing file extension using qrun.g4b and .isowb files
  2. memtest86 32-bit UEFI boot file added - if you UEFI-boot a 32-bit or 64-bit system from a FAT32 E2B USB drive it will now run memtest86 
  3. Make_E2B_USB_Drive.cmd now checks for Admin rights and also removes EFI folder to save space if you formatted it as NTFS (as you cannot directly UEFI-boot from an NTFS partition). 
  4. New .imgPTNAUTO file extension supported (no user prompt to switch partitions). 
  5. AUTOCSM variable in MyE2B.cfg will now cause all .imgPTN files to auto-run, just as if they all had the .imgPTNAUTO file extension.
  6. Added a 'Measure USB Performance' menu entry into Utilities menu to allow testing of BIOSes with slow USB access
  7. Bugfix for ISOs with long filenames ending in .isoWB. 
  8. Sample WinBuilder .mnu changed for same fix as above. 
  9. New grub4dos 0.4.5c grldr version. 
  10. File enumeration speed improvements - should make for faster booting on systems with slow BIOSes. 
  11. linux script fmt.sh added to format a USB drive as an E2B drive under linux.

Slow to load the Main Menu?

Several people have reported in the E2B forum that E2B takes several minutes to get to the Main menu even when using a fast USB 3.0 flash drive. This is due to the particular system BIOS having very poor quality USB 'drivers' which makes USB communication very slow. Because E2B needs to access all files in the \_ISO\MAINMENU folders and \_ISO\WINDOWS folders several times during start-up, this can result in a long wait on systems with these slow BIOSes. The speed does not depend on how fast the CPU is or how fast the USB drive is (though that can affect timings), it depends on how well written the USB driver code is in the BIOS (good code will use interrupts and DMA, bad quality code will use polling which can cause long delays as each USB bus 'message' is sent or received). Because BIOS vendors tend to use the same code modules for different systems, you may find that the same 'family' always have poor USB performance (e.g. AWARD V6.00PG BIOS). Of course, once you boot to an Operating System  such as linux or Windows, the OS uses it's own USB drivers and we will get decent USB communication speeds.

You can now run a 'Measure USB Performance' test from the Utilities menu (which is really measuring the BIOS USB driver performance as well as USB speed!) to see how long 100 file accesses takes (and also 1000 file accesses). You should see that most systems take between 2-5 seconds for 100 accesses, but slow BIOSes can take 60 seconds!

Note that this test does not measure data transfer performance, just directory access speeds. Also, grub4dos produces faster results on FAT32 USB drives than on NTFS drives, so if comparing times between different USB drives, always use the same formatting for E2B.
Virtual Box + E2B on a USB HDD (100lp=0.8 seconds)

An indication of a BIOS problem, is that booting to E2B using the RMPrepUSB - QEMU button (which is normally much slower than a real system) is faster than when booting on the real 'bad' system using the system's BIOS USB code.

QEMU is normally slower than a real system.
QEMU + E2B on a slow USB Flash drive - 100 loops=16 seconds
On an EeePC (an average BIOS), the same USB drive - 100 loops=3 seconds.

To check for a bad BIOS, boot to E2B on the 'bad' system, and then switch to grub4dos 0.4.6a (it is listed in the Main menu) and then load the grub4dos 0.4.6a USB 2.0 chipset driver (which is listed in the Main menu after loading 0.4.6a). If the USB driver loads successfully and detects your USB drive, you can repeat the  'Measure USB Performance' test to see if file access speeds have improved. Typically, 100 accesses will take less than 2 seconds when the grub4dos USB driver is loaded (if it has recognised the USB 2.0 chipset in the system)! You can use a USB 3.0 drive, but it must be connected to a USB 2.0 port. Unfortunately, the grub4dos USB driver does not recognise all USB 2.0 chipsets/adapters and so it is pot luck whether it works or not on each system.


If the grub4dos USB driver does work, you can enable it on each E2B start-up by setting a variable in the \_ISO\MyE2B.cfg file (set GRUB_USB=Y).

If the grub4dos USB driver does not recognise your chipset or for tips on getting E2B to load faster, see the FAQ page.

If you already have an earlier version of E2B, just download the smaller 1.54 (non-DPMS) version and overwrite the files on your E2B USB drive.

grub4dos secrets!

As you may know, E2B and most of the Tutorials on www.rmprepusb.com use grub4dos. I have got to know grub4dos pretty well and I love it's flexibility. It has been improved quite a bit in the last few years (thanks chenall and tinybit!) and there have been some changes which have not been reflected in previous documentation or guides.

So, I just thought I would point out a few articles on the www.rmprepusb.com website which you might find useful:

Tutorial 21 is a grub4dos tutorial - useful for beginners and the more advanced user.

Tutorial 71 is about some of the programs which you can run under the grub4dos environment, such as wenv, hotkey, chkpci, fat and bios. It also describes how to run grub4dos batch files.

Tutorial 57 is about configuring grub4dos menus, hiding startup messages, making a silent splash screen, configuring 'secret' keys, etc.

Finally, Here you will find a page about the special hidden, secret and undocumented features of modern grub4dos, also what memory areas grub4dos uses, what internal variables are available, new commands and operators, the undocumented Fn. functions calls and lots of other goodies!

If you want to get a feel for grub4dos batch files, have a look at any of the Easy2Boot grub4dos batch files (they usually have a file extension of .g4b) - an advanced coding example can be found in the dpms2.g4b batch file if you are feeling really geeky!

Linux script to install Easy2Boot to a USB drive

The latest version now includes a fmt.sh bash shell script which can be run from a linux OS and it will format a partition as FAT32 on the specified drive, copy over the E2B files and then run bootlace to install grub4dos. There is also a fmt_ntfs.sh script to create an NTFS E2B drive (v1.83+).

I have tested it in a VM (VBox)  using Linux Mint Debian Edition (64-bit) and Ubuntu 14.04.
Of course, there are lots of linux distros and it may not work on all of them.
As it formats a partition, you need to be careful when using it - you have been warned (but it has been independently tested here)!

The E2B download is on this page (linux users will probably not need to use the much larger DPMS version which you will only want if you are intending to install XP from E2B).

Once you have made your E2B FAT32 USB drive, just add all your ISO files to any one of the menu folders - e.g. \_ISO\MAINMENU or \_ISO\LINUX.

Alternatively, you can add your payload files into the downloaded files first, before you run the fmt.sh script. This is useful if you want to make a fresh, contiguous E2B drive and it is often quicker to make a fresh drive, rather than running defragfs to make any added/changed files contiguous.

Here is a screenshot of the script in action. You need to run chmod first before you can run the script.
The script can be found in the \_ISO\docs\linux_utils folder after extracting the files from the download (the folder also contains defragfs which you can use to make your ISO files contiguous - only works on FAT32 volumes).

E2B v1.83+ includes a fmt_ntfs.sh script to format a drive as NTFS, plus the udefrag utility to defragment an NTFS drive. Read the ReadMe file for details.

.imgPTNAUTO file extension is supported in E2B v1.54

E2B v1.54 will support the new .imgPTNAUTO file extension.

This differs from the .imgPTN file extension in that the user does not see the prompt to press a key to switch to the new partition; instead as soon as you select the menu entry, the partition is switched and you are immediately presented with the CSM menu.

For the other variations of .imgPTN files, you can make a special .mnu file, e.g. both of these will go straight to the CSM menu:

title Clonezilla AutoCSM
/%grub%/qrun.g4b    FORCE.imgPTNAUTO     $HOME$/clonezilla-live-2.2.2-37-i686-pae.imgPTN
boot

title Clonezilla AutoCSM
set AUTOCSM=1
/%grub%/qrun.g4b    $HOME$/clonezilla-live-2.2.2-37-i686-pae.imgPTNLBAa23
boot

You can also use  set AUTOCSM=1  in a \_ISO\MyE2B.cfg file to make all types of  .imgPTNxxxx files auto-run to the CSM menu.

The new QRUN.g4b file that supports this is available for download in the easy2boot Alternative download areas (see V1.54Beta.zip file).

UEFI-boot FatDog (Puppy) linux from your Easy2Boot USB drive

FatDog (a 64-bit version of Puppy) now supports 64-bit UEFI booting. Here is how to add it to Easy2Boot and enable UEFI booting.



1. Download FatDog64-631.iso from here
2. Extract the contents of the ISO to a new empty folder on your Windows hard drive - e.g. C:\temp\fatdog631
3. Extract all the files from the efiboot.img file to the C:\temp\fatdog631 folder - you should now have a C:\temp\fatdog631\efi folder (amongst others)...

4. (optional) delete the [BOOT] folder if there is one and the efiboot.img file
5. Drag-and-drop the C:\temp\fatdog631 folder onto the Windows Desktop MPI_FAT32 shortcut to make a .imgPTN file (see www.easy2boot.com - MakePartImage for details). if you want the persistence feature (Save file), increase the size of the FAT32 partition (e.g. add 500MB).

Note that if there is not enough space and Puppy creates a very small Save file, it will not boot until you delete the Save file!

6. Copy the .imgPTN file to your E2B USB drive's \_ISO\MAINMENU folder (or other menu folder)

You can now boot to E2B in the normal way and select the new .imgPTN file. Once you have switched partitions you can UEFI-boot from it (64-bit systems only) or use Clover to UEFI-boot directly or use the CSM menu to boot in MBR mode.

This is the first reFind UEFI boot screen


This is the next menu after pressing [ENTER]


Note: If you wish you can skip the reFind UEFI boot menu and also save some file space as follows (do this after step 4 above or in the partition image itself):

1. Delete all files and folders under the C:\temp\fatdog632\EFI\boot folder
2. Move the \EFI\grub2\grub2.efi file to the \EFI\boot folder
3. Rename the \EFI\boot\grub2.efi file to bootx64.efi

You should now have a single file under the \EFI folder called \EFI\boot\bootx64.efi. When you UEFI-boot, you will see the black menu screen shown above.

Please tick 'funny' 'interesting' or 'cool' or add a comment to let me know which posts you most enjoy.



64-bit and 32-bit UEFI for Puppy ISOs

You can drag-and-drop the ISO onto the MPI_FAT32 shortcut to convert it to a .imgPTN file (choose 37 for linux option). I used tahr-6.0.6-uefi.iso. Don't forget to increase the default size suggested if you want to use the Save feature and have persistence.

Switch to the .imgPTN file and the FAT32 partition.

Now extract the contents of the \efi.img file to the root of the E2B drive (i.e. the new FAT32 partition should now contain \EFI\BOOT\BOOTX64.EFI).

Now it will be UEFI-64-bit bootable.

To add the 32-bit grub boot file, download http://distro.ibibli...2.00-i686-1.txz

Extract the \grub2-efi32-2.00-i686-1.txz\grub2-efi32-2.00-i686-1.tar\usr\share\grub2-efi\grubia32.efi file using 7Zip

Copy it to the \EFI\BOOT folder and rename it to bootia32.EFI, so you have now...

  • \EFI\BOOT\bootia32.efi
  • \EFI\BOOT\bootx64.efi
  • \grub.cfg (should already be present)
Now you should be able to UEFI 32-bit/64-bit and MBR boot.

Have you tried PXE booting yet?

Nearly all modern computers support Network Booting (aka PXE booting).
You may have seen the option to boot from the network listed in the BIOS boot options of a BIOS Setup menu.

Tutorial #76 on my RMPrepUSB site describes how to set up SERVA which is an incredible Windows utility which can set up any Windows system to function as a PXE server (as well as a normal PC).

Normally, you would need to have access to the network DHCP server (the one that dishes out IP addresses to all the computers on the network) in order to configure PXE booting. The unique thing about SERVA is that you don't need to fiddle with the network DHCP server at all. This is a real boon for home users who usually use their router as the DHCP server. It is also a boon for companies who have a multi-server network and don't allow or want their employees to fiddle with the servers.


The home site for SERVA is here and it has lots of documentation on how to boot loads of different OS's - see here for a list of non-Windows payloads that you can network boot (includes Fedora, Ubuntu, Kali linux, Debian, android x86, GParted and even FreeDos for performing a BIOS upgrade).
To install Windows across the network, it is necessary to ensure that the OS you are booting to has the necessary network drivers included, because once it boots to the Windows PE environment, it will need to pull the install files across the network from the SERVA PC to copy onto the systems hard disk.
SERVA was featured in PC WELT recently (Issue 5 - pg.55)

The free 'Non-Supporter' home-trial version of SERVA can be used to install Windows across the network. The 'Supporter' version is 29.99 and has more features and is used by many companies - see here for a list.

Something to try during the Summer holidays perhaps?

Add a Cold Boot Attack to Easy2Boot

Jamil recently contacted me and asked how to get the Cold Boot Attack (video) (skip to the 3 minutes point to save time) code 'scraper.bin' to work on an Easy2Boot USB drive. This allows you to capture the contents of a computer's memory onto a USB drive (even if it has been switched off for several seconds!). The idea is that the computers memory may still contain un-encoded AES encryption codes, passwords, etc. which can be deciphered later, once the memory's data has been safely captured.
Note that scraper.bin also displays the last key presses from the keyboard buffer too!

The idea that we came up with for getting this to work with Easy2Boot is now available for all to use, so check out Tutorial 124!

The following scenario of retrieving data from a system that is switched off seems rather far fetched however and may be something that you would only see Tom Cruise doing in Mission Impossible!:



1. User shuts down PC and walks away
2. Tom approaches system from the ceiling and takes it apart
3. Tom uses freezer spray on the internal DIMMs
4. Tom removes the DIMMs and keeps them cold on top of a frozen cold pack or a small flask of liquid Nitrogen which he has in his utility belt
5. Tom replaced the DIMMs with identical ones which he happens to have with him and leaves the building
6. Tom takes the DIMMs to another system in his lab which takes the same sort of memory
7. Tom quickly fits the DIMMs to his PC and his E2B+'scraper' USB drive and switches on the system - all data from the DIMMs are saved to the USB drive
8. Tom analyses the data, gets all the encryption keys and saves the world!

How to add Floppy Disk Images to Easy2Boot

Floppy disk images usually have the .ima or .img file extension.

You can just add these to your E2B USB drive in the usual way by drag-and-drop to any suitable menu folder (e.g. \_ISO\MAINMENU or \_ISO\DOS or \_ISO\UTILITIES or even \_ISO\LINUX, etc.).

Most people will want to boot to DOS (either FreeDos or MS-DOS) in order to run a DOS utility such as a BIOS update utility or a DOS utility such as HWInfo.

The RMPrepUSB Tutorial 33 includes details on how to make such Floppy Disk Images.

When Easy2Boot boots from a .ima or .img image, the USB drive will be mapped as a floppy disk device (i.e. A:). Any hard disks that are present in the system will appear as C:, D:, etc. but of course, the files on them will only be accessible to DOS if they are FAT16 or FAT32, unless you also have a DOS NTFS driver loaded. The whole floppy disk image is loaded into memory so that you cannot change the files in the image file accidentally (note: if you wish to boot directly so that you can change the contents, use a .IMArw file extension as in v1.54 and later versions).

For instance, you can download the DOS version of HWInfo from here and add it to a floppy disk image as follows:

1. Download the latest DOS version of HWInfo and unpack it fully.
2. Download the FREEDOS_288.zip file from Tutorial 33 and unpack it to obtain the FREEDOS_288.ima file.
3. Mount the .ima file using WinImage or ImDisk.
4. Copy the two HWInfo files (.exe and .dat) to the floppy disk image.
5. Quit WinImage/ImDisk and save the changes.
6. Copy the .ima file to your E2B USB drive and give it a suitable name - e.g. \_ISO\MAINMENU\HWInfo.ima


When you boot from the image, type HWINFO at the A: DOS prompt to run the program.
If you prefer, add HWINFO to the bottom of the \fdauto.bat file to make it run automatically.

A ready-made payload file HWINFO.IMA.GZ is available in the Alternate Download - Other Files areas. There is also a CPUINFO.IMA.GZ too.

You can add BIOS utilities in the same way.

If you use the .ima file extension, the USB drive will be accessible from DOS as the first hard disk in the system. Any internal hard disks will be the 2nd, 3rd, 4th etc. Of course, FreeDOS will normally only be able to access them if they are FAT16 or FAT32.

Larger 'floppy' images
If you need a larger image, use ImDisk to create a Dos.img file of whatever size you want as a virtual drive. 
Copy your files onto the virtual drive and then 'Remove' the virtual drive. 
Then copy the Dos.img file to \_ISO\MAINMENU. 
If you like, you can use the contents of RMPrepUSB's FREEDOS_USB_BOOT folder as a source for your bootable FreeDos files (press F3 in RMPrepUSB to see the folder).

Use E2B's FreeDOS floppy image

Here is an easy way to run most DOS-compatible software just by copying the files onto your USB drive.

1. Download HWINFO for DOS and extract the files to a new folder on your E2B USB drive.
Keep the folder name within 8 characters (I used \HWINFO).
You can use the first NTFS partition of the E2B USB drive, but if you have a FAT32 partition on your USB drive, this you will not need to load the NTFS driver (which is a bit flakey!).
2. Now Legacy boot to the E2B DOS menu and run the FreeDOS floppy image.
3. Choose the NTFS option if your files are on the first partition.
4. Now run the program (this assumes the C: drive is the volume with the \HWINFO folder)

C:
cd \HWINFO
HWINFO

Re-install linux onto your Asus EeePC using a USB drive

I have added Tutorial 123 to the RMPrepUSB site for anyone wanting to re-install linux onto their Asus EeePC 701 from a USB drive using the 900MB EeePC 701 ISO download.

The larger EeePC downloads (e.g. v1.7  1.9GB) include images for many more EeePC models which can be run Live or can be installed. These larger ISOs can simply be added to your E2B USB drive as .ISO files. See  Tutorial 123 for more details.


Add 64-bit android for x86 Intel Architecture to your E2B USB drive

You can download various versions of 64-bit android for different Intel platforms from here.

Note that these are Betas and so I would recommend you do not try to install it onto your working Windows system! Luckily, most images contain a Live boot option so we can test it out without installing it.

The downloads are in the form of .zip files and contain a disk image which can only boot via UEFI.

To add these to your E2B drive you need to:
  1. Use 7zip or WinRar, etc. to find the live.img payload file which will be inside the .zip download file, e.g. android-4.4.2_r1-ia1-haswell_generic-userdebug.zip has a live.img file under \out\target\product\haswell_generic. I picked this one for my Z87 Haswell system.
  2. Extract  the live.img file from the .zip file file to a temporary folder (e.g. C:\temp\live.img).
  3. Drag-and-Drop the C:\temp\live.img file onto your MPI_FAT32 Desktop shortcut to automatically create a .imgPTN file
  4. Copy the new live.imgPTN file to your E2B USB drive (e.g. to the \_ISO\MAINMENU folder or \_ISO\LINUX folder) and rename it to something more meaningful (e.g. android_x64_442r1.imgPTN)
Now you can boot in MBR mode (or use QEMU or VBOX) and select the new .imgPTN file to swap over the E2B drive to the new partition image and then go and UEFI-boot it from the correct Intel Platform (e.g. a Haswell-based system in my case). 

Note that UEFI booting from VBox will probably fail as it will refuse to boot from an incorrect CPU\chipset platform.

How to add Android x86 + Persistence to your Easy2Boot multiboot USB drive

You can run android x86 on an Intel\AMD x86 system from an ISO with persistence directly from your E2B drive.

The steps are:

1. Download a suitable version of Android x86 as an ISO file. Note that you can obtain versions to match different systems (e.g. eeePC, etc.). Using the wrong version on some systems may result in problems with the mouse or touchscreen, etc.
  • android-x86-4.0-r1.1-asus_laptop.iso  for ASUS Laptops/Tablets 
  • android-x86-4.0-r1-amd_brazos.iso     for AMD Brazos platform 
  • android-x86-4.0-r1-eeepc.iso          for ASUS Eee PC family 
  • android-x86-4.0-r1-s103t.iso          for Lenovo S10-3t tablet
  • android-x86-4.0-r1-tegav2.iso         for Tega v2(Atom N455)
  • android-x86-4.0-r1-thinkpad.iso       for IBM thinkpad tablet
  • android-x86-4.0-r1-tx2500.iso         for HP tx2500
2. Copy the ISO file to a MNU folder on your E2B USB multiboot drive (e.g. \_ISO\MAINMENU\MNU or \_ISO\LINUX\MNU).

3. Copy the android_x86_Persistent.mnu file to the same folder as your Android ISO file.

Then Edit the .mnu file so that the ISO filename matches your ISO filename.

4. Create an ext2 file in the E2B root (top level folder) using the RMPrepUSB - Create ext2 FS button - the file name should be \android-rw, but the volume name and size can be whatever you like.

You can instead use Make_ext.exe which is already on the E2B drive. (\_ISO\_Make_Ext.bat).

5. Make all files contiguous using RMPrepUSB - Ctrl+F2.

You can find the android .mnu file in the Alternate Downloads area (link on this page) or in later versions of E2B in the \_ISO\docs\Sample mnu files folder (1.54 or later).

Note that for persistence, we must specify the linux drive name in the kernel parameters. The .mnu code tries to calculate this, but you can override it by typing in the correct letter if it guesses wrongly.

For instance, if you boot from your E2B USB drive on a laptop containing a single HDD, the .mnu file will guess that the USB drive will be 'sdb' once android boots - if this is incorrect, and it will actually be 'sdc' then just type c followed by the [ENTER] key when you are prompted by the E2B menu. If you don't type anything within 2-3 seconds then it will just use the calculated value. If the drive letter is wrong, you just won't get persistence!

Tip: You can tell what drive letter the E2B USB drive is as android boots.

In this case it was a  (sda)

If your mouse is not working in android x86, use the TAB, ESC and ENTER keys as well as other keys to navigate the menus and icons.

Note: I had a few problems booting some of the ISOs in 'Resident' mode on some systems, but the Guest mode seemed to work. Android_x86 also did not seem to like VBox virtual machines much!

See also this video.

UEFI-booting

It seems that the .iso files do not work well with UEFI-booting and there is a separate .img download for UEFI-booting. Simply drag-and-drop one of the EFI .img files onto the MPI_FAT32 desktop shortcut (after installing the MPI Tool Kit), and create a .imgPTN file. This should now UEFI-boot (but won't MBR boot!)

You can also try the E2B Grub2 menu system which can boot to PhoenixOS via UEFI&MBR 32&64 and remix via UEFI&MBR 64-bit.

Booting Windows8.1ToGo from a 'Removable-type' of USB Flash drive

I was recently contacted by 'JFL' about getting Windows8ToGo working on his 64GB SanDisk Extreme flash drive.

He was using Windows 8.1 Enterprise as the source and was following my earlier blog here.

The problem was that although he could install Windows OK, it would not boot.

His SanDisk Extreme was listed as being of the Removable type in RMPrepUSB and it was suspected that this may have been the problem because I found some comments from madscye and creosotechris here which sounded suspiciously like something has changed in Win8.1!

Now, in the past, I have had Win7ToGo booting from a USB removable flash drive OK many times. I have also booted Win 8 in the past on a removable USB Flash drive and that had worked OK.

Experiment 1
I already had a  21GB Win8.1ToGo.imgPTN file which I made earlier on my E2B USB HDD and I copied that onto my 32GB USB 3.0 Corsair GT E2B Removable-type drive (after deleting some ISOs to make room!).
I switched partitions using E2B and then I ran BCDBOOT on it to set the BCD correctly to boot from the different drive.
Result: it booted fine under VBox (which treats the USB drive as an HDD) but NOT on my Acer laptop (ever-lasting spinning circle of dots!).

So I did another experiment...

Experiment 2 - fresh install
1. Using DISM, Install Win8.1 Enterprise onto a 16Gb Lexar JumpDrive USB 2.0 which appears as a Fixed Disk (install took about an hour!)
2. Boot from the Lexar USB drive on an Acer Aspire 7741G laptop - go through user setup to Desktop (again very slow!).
3. Reboot and check boots from USB drive OK - all was working fine.
4. Use Bootit.exe to Flip the Bit so the USB drive is now a Removable drive
5. Boot from it on the Acer laptop again
Result: FAIL! (ever-lasting spinning circle of dots)

Experiment 3
1. I re-ran BootIt.exe and flipped back to a Fixed Disk type again
Result: The Lexar boots just fine!

So proof that Win 8.1 ToGo must be run from a Fixed-disk type of  USB drive!

[Update] Win10 (first release) also has same issue. It can be overcome by booting from a VHD file containing WindowsToGo.
Windows 10 Creator now allows us to use Removable or Fixed disk USB drives for flat-file booting - hurrah!

E2B Updates

In the last few days there have been a few small changes to E2B.

E2B v1.53 - has TRAD_CHINESE language added (thanks to Andrew :-). It also has a bugfix to the Make_E2B_USB_Drive.cmd script which used the wrong version of grub4dos to install code to the MBR of the E2B USB drive (reported by JF-L). This did not cause a problem unless you tried to boot a .imgPTN file - then you would get an error from E2B Qrun.g4b complaining about 'No Grub4dos installed to the MBR of this drive!' I have now changed the script and also changed Qrun.g4b so any version of grub4dos MBR code can be used. If you have seen this error message, it can be fixed by using RMPrepUSB to reinstall grub4dos to the MBR of your USB drive (recommended) or by updating your E2B USB stick to v1.53.

Info: The version of grubinst.exe used in RMPrepUSB has been modified by me to make it more boot-compatible on a wider range of systems than the standard grubinst.exe (the standard version is called grubinst_new.exe in RMPrepUSB). The boot code in the standard grub4dos MBR does not boot on some systems due to some BIOSes detecting what they think is invalid boot code. The special version of grubinst.exe in RMPrepUSB is limited to installing grub4dos to drives numbered 0-9 only, but fixes this problem, so that these few weird systems will also boot to grub4dos. That is why I recommend you always prepare your E2B USB drive using RMPrepUSB or the Make_E2B_USB_Drive script (and for other reasons too, like FAT32 writes are up to 10% faster on a flash drive if you use RMPartUSB to format them!).

The other update is to the MPI Tool pack - MPI_Tool_Pack_Plus_CloverLite_035. This has been updated to version 035a. It has the latest version of ImDisk now. Also, there was a problem if you tried to run  'RestoreE2B (run as admin).cmd' from Windows Explorer by using right-click+Run as Admin AND if you had not installed RMPrepUSB into it's default location on your Windows system (reported by Anderson - thanks!) - this is fixed in the new version.

P.S. No more language files have been sent to me yet - why not achieve some small amount of fame and world gratitude by translating the E2B strings.txt file into your own language?  Instructions are in a previous blog post here. You can even use Google Translate to do most of the grunt work! If you are German or Spanish speaking, please can you check the existing STRINGS.txt files as there are probably some errors as I used Google Translate to make them!

Another E2B language and @DED-LEGO@

Mr TSAI has kindly sent me a Traditional Chinese language file.

The latest languages will always be in the E2B_LANGUAGE_PACK.zip file located in the Easy2Boot Alternate Download areas.

These are now:
Chinese Simplified
Chinese Traditional
English
German (Beta)
Spanish (Beta)

Memoarfaa has confirmed that the @DED-LEGO@ GFX menu package works with E2B - see the reboot forum posts starting here. You will need to increase the default number of entries from 15 however by re-compiling the file (why not try 100?).

@DED-LEGO@ showing the E2B menu with walking penguin and animated clock, etc.

Please note: E2B does not fully support GFX Menus or @DED-LEGO@/RIPPER menus and I am only willing to spend a few minutes on any issues/questions you may have concerning these.

Easy2Boot v1.52 includes SPANISH, GERMAN and CHINESE support

The Spanish and German STRINGS.txt files probably need some corrections. If you see any problems please just modify the STRINGS.txt file and send me the new version.

Tuesday, 8 July 2014

Sprechen sie Deutsche?

I have tried to convert E2B into German even though I failed my German O-Level!

If you speak German, please you can check my translation by downloading the German STRINGS.txt file and copying the STRINGS.txt file to your Easy2Boot    \_ISO    folder. This file is already in v1.52.

I expect there are some issues - if so please just edit the STRINGS.txt file and test it.
Then email me the corrected version! Use E2B v1.52 to test it.

Don't forget to test the XP, Vista and Win8 installs to (you can use a dummy ISO file).

Note: first version had a $$STRl1x1 problem when loading Windows Install menu - please re-download the corrected version if you have the old version.

To make a STRINGS.txt file in your own language, see the previous blog for instructions.


Thanks
Steve

Please send me your own language files!

Mr Lin has translated E2B v1.51 into Chinese. The new STRINGS.txt file is available on the E2B Downloads page and will be added into the next version of E2B.


If you would like to translate E2B into your own language, just make a new STRINGS.txt file.

Please send me your new STRINGS.txt file and I will add it to E2B and your fame will be immortalised!

Here is the best way to do it. First make an E2B USB stick if you don't have one already, then...

1. Copy the \_ISO\e2b\grub\ENG\STRINGS.txt file to the E2B drive's  \_ISO folder - always use latest BETA version of E2B (do not use an earlier version).

2. For test purposes - ensure that there are ISO files in all E2B menu folders - the ISO file can be just a one-byte dummy file (e.g a small .txt file renamed to dummy.iso). It is easier to use dummy files because they won't boot and will just return back to the E2B menu again.

Place a dummy ISO file in each of these folder:
\_ISO\ANTIVIRUS, AUTO, BACKUP, DOS, LINUX, MAINMENU, UTILITIES, UTILITIES_MEMTEST, WIN and WINPE folder.
Also add an ISO to each of the folders under the \_ISO\WINDOWS folder so that the Windows menus will appear. Ensure there are two or more ISO files in the XP folder (if only one ISO then it will be automatically selected by E2B and you may not see all the dialogue strings).

3. Boot from the E2B stick using an emulator\VM - if using RMPrepUSB and QEMU - use CTRL+SHIFT+F11  (not the F11\QEMU button) - if using VBOX - do not use DavidB's VMUB.
This allows you write access to the USB drive without needing to quit the emulator/VM each time you make a change.

4. Load the \_ISO\STRINGS.txt file into your favourite text editor (e.g. Windows NotePad) - ensure that it supports UTF-8 format so you can save non-ASCII characters.

5. Edit the English text on the right-hand side of all the $$STRxxx= keywords and change it into your own language.

Tip: You may find it quicker to upload the English Strings.txt file into Google Translate and cut and paste the translated text back into your STRINGS.txt file.
You can use FIXLANG.cmd to tidy up the mess that Google Translate makes of it as follows:
  • 1. Paste the English text into Google Translate and select your language
  • 2. Cut and paste the new translated text into a STRINGS.txt file on a folder on you Windows disk
  • 3. Download the FIXLANG.zip file and extract the files that are in it into the same folder as your STRINGS.txt file
  • 4. Double-Click on the FIXLANG.CMD file to fix the errors. A NEW.txt file will be made and then loaded into NotePad. You can re-save it as STRINGS.txt if it looks better.
FIXLANG.cmd will fix many of the problems caused by Google translate but you will still need to check each line carefully. I recommend using WinMerge to compare the new NEW.TXT file with the original English STRINGS.txt file.

To replace strings in more than one file, I recommend 'Find and Replace' (FNR.exe). FNR is a standalone .exe. It allows you to preview results before you change any files.



6. Save the file (don't quit the text editor)

7. Hit F9 in the E2B emulation session to reboot E2B - the new changes should now be visible.

8. Go through all the menus and also all the XP and Windows Vista and Windows 8 install screens (you can use a dummy ISO file for these).

9. GOTO STEP 5 and repeat until it is all perfect!


Tweaking

This is the hardest and most time-consuming part!

You will need to check each line carefully, especially any \n  syntax and file paths such as \\_ISO\\AUTO. Check all $$STR keywords and any $[0104] colour strings have not been corrupted.

Also, any question which requires a Yes/No answer must keep the same letters because E2B will expect either the 'Y' or 'N'  key to be pressed - e.g.  Ja/Nein (Y/N)  is correct, but Ja/Nein (J/N) may not work because E2B is expecting 'Y' not 'J' for Yes.

Hotkeys
Any string that starts with a ^hotkey symbol must not be translated - e.g.

$$STRm016=^Ctrl+A ANTIVIRUS-Menü                    [Strg+A]\n Antivirus-Dienstprogramme

because grub4dos hotkey names are coded keywords. You can change the letter from A to something else but don't change ^Ctrl+.

Underlined headings

Some headings are underlined using  ===== , e.g.

This is a heading
=========

The number of = characters must match the number of characters in the heading - e.g.

$$STRb001=XP-Installation - Schritt 1 \n===========================\n\n$[0104]WICHTIG: Du musst wieder von einem USB-Laufwerk starten und danach Schritt 2 durchführen! \n

The heading (XP-Installation - Schritt 1) has 27 characters and so there must be 27 = signs for the underline.



Finally - contact me and let me know what language and locale it is (e.g. Spanish, Catalan, Portuguese-Spanish, etc.). I will reply by email so you can email me the new files.

Also you can translate the F1.cfg file too if you like!

E2B v1.51a (with XP bugfix) and method for adding multiple background bitmaps to E2B


  • I have had three reports from users recently complaining about the Step 2 XP Install stage not working. When I looked at the XPStep2.g4b file, I found that I had accidentally commented out the line that loads the XP ISO into memory! The bug existed in all versions between v1.32 and v1.51! This has now been fixed in v1.51a. This probably explains why there have been some complaints (it is not always necessary to load the ISO into memory, but in helps in cases where XP does not contain compatible USB drivers and so cannot access the ISO file when it boots to XP).
  • I have now documented how you can have multiple wallpaper background bitmaps here.
    You can have one bitmap displayed whilst E2B is enumerating files and another for the Main menu. You can also have different bitmaps for each sub-menu. Here is a demo...
Note: MyE2B.cfg needs 'call Fn.70 3' so you can see the background during file enumeration.

\_ISO\MyE2B.cfg
=============
!BAT
call Fn.70 3


\_ISO\Mybackground.bmp.gz (first 'blue' image)

Read more: http://www.easy2boot.com/configuring-e2b/multiple-backgrounds/

See the YouTube video on how to set up multiple menu backgrounds by Liu Evan here.

To update E2B, download the non-DPMS zip file and extract the files onto your E2B USB drive - you don't need to download the large DPMS zip file even if your previous version was with the DPMS drivers. Then use the \Update_E2B_Drive.cmd file to update your E2B drive.



New GEGeek Tech Toolkit released

In case you missed by previous blog about the GEGeek Tech ToolKit here, I just thought I would mention that a new version is now available from the GEGeek website.

It is a hefty 1.7GB download but worth adding to your USB Flash drive as it contains hundreds of useful Windows tools and utilities. Click on the GEGeek Tech Toolkit link to get to the download.

Easy2Boot v1.51 now available



v.1.51 2014-07-03
  1. .imgPTN is now equivalent to .imgPTNLBAa (use .imgPTNna for old .imgPTN behaviour)
  2. \_ISO\BACKUP_LINUX folder deleted
  3. Small changes to English STRINGS.txt
  4. Bugfix aroung CONTIG.ISO and source ISO file size detection (failed size check if >2GB)
  5. Small code/message changes
  6. English strings.txt file is now always loaded after primary language.
The main change is Item #1 - so that you do not have to rename .imgPTN files to the more compatible/reliable files extension of .imgPTNLBAa, I have now made these two file extensions both behave as .imgPTNLBAa did (i.e. both file extensions now modify the partition parameters for LBA access and set the partition as Active).

If you don't want the partition set to Active and you don't want LBA parameters to be used (i.e. the 'old' .imgPTN behaviour) then use the new file extension of .imgPTNna (na=non-active).

Change #6 - This ensures that if a $STRxxxx string is missing from the chosen language file, then the English version will be used instead. Thus, if a new $STRyyyy string is added at some later date to the ENG\STRINGS.txt file, the old Spanish strings.txt file (which will not have the new $STRyyyy string) will not report an error but will just show the English translation if the Spanish translation is missing. i.e. the 'fallback' string translation will be English as I can always keep this up to date.

Say No! to the European 'Right to be forgotten' rule

You may have read recently that the European Court of Justice passed a ruling that search engines should not return any results that are inaccurate, inadequate, irrelevant or excessive (see here for the details).

Note: if someone asks for a search result to be removed because it is 'irrelevant', then surely it cannot actually be irrelevant because is it was irrelevant then they wouldn't be asking for it to be removed! i.e. Catch 22!

The original case was about a Spanish man...
1) What is the case about and what did the Court rule? 
In 2010 a Spanish citizen lodged a complaint against a Spanish newspaper with the national Data Protection Agency and against Google Spain and Google Inc. The man complained that an auction notice of his repossessed home on Google’s search results infringed his privacy rights because the proceedings concerning him had been fully resolved for a number of years and hence the reference to these was entirely irrelevant. He requested, first, that the newspaper be required either to remove or alter the pages in question so that the personal data relating to him no longer appeared; and second, that Google Spain or Google Inc. be required to remove the personal data relating to him, so that it no longer appeared in the search results.

and their decision was...

While the Court ordered Google to delete access to the information deemed irrelevant by the Spanish citizen, it also emphasised that the content of the underlying newspaper archive should not be changed in the name of data protection (paragraph 88 of the Court’s ruling). The Spanish citizens’ data is still accessible but is no longer ubiquitous. This is enough for the citizen’s privacy to be respected. 

So a Citizen can deem some piece of information about himself is 'irrelevant', it is perfectly OK for the information to be present as an article on the web, it is not breaking any law, but we (the public) are not allowed to search for it! Because of the data protection act, the source should not be changed, but the Search sites which can find the source sites should be changed. Surely this is circumventing the data protection act?

Recently a British journalist queried why some of his article 'hit results'  were removed by Google after receiving a letter from Google telling him that they would be omitted in future due to the ECJ ruling and a request from 'some 3rd party' to do so. In other words, someone just filled in a form provided by Google and they removed the search results. They recently reversed this decision (see here).

I simply cannot understand why the entire world internet population (and Google) has not objected to this? The ruling says that even if the 3rd party provider (e.g. Google) has servers outside Europe, the rule still applies as long as the 'service' is made available to Europeans.

The fine for not removing these results is pretty massive (up to 2% of annual worldwide turnover - note the word turnover - not profit or net income but turnover!). And that is just for 1 result being returned when it shouldn't be.

So Google 'detects' a European I.P address and censors our results (if using google.co.uk for instance). So we can look forward to loads of non-European server sites acting as Google proxies for Europeans who want to do Google searches and see ALL results. Apparently, Google have had over 50,000 'please forget me' requests so far!

Note: There is a way around this, use Google.com instead of your default Google (e.g. google.co.uk). If you go to the main Google page, the URL will be changed to your local country page automatically - however you can use google.com by clicking on the bottom-right 'Use Google.com' link:


OR just use DuckDuckGo which is also anonymous and does not take into account who you are or what you have been searching for recently.

Here is another more local case of why this ruling is insidious (and doesn't even achieve it's objective anyway) from my local press! So you can get past crimes that you committed just 8 years ago 'expunged'.

Hypothetical Example:

If a man was taken to Court in 1979 for child abuse but was found innocent (or even guilty!), could he later (how much later?) get the search results for that Court case removed? What if 20 different children or adults accused that same person of abusing them over a 20 year period between 1978 and 1998 but no further action was taken due to lack of evidence - could he also get these results removed by Google and the other search engines? According to the ECJ, he could as they are 'irrelevant'.

Now what if your child accused that man of abusing them yesterday and you did an internet search and either,
a) found nothing
or
b) found dozens of articles about the same man involved in similar situations

How would that affect your decision about whether to believe your child and whether your child and other children were in danger from this man and whether to go to the Police?

What message is this sending to society? Go out into the world and commit crimes, disappear for a year or so, get the crimes removed from all the search engines and no one will know. You are then free to commit more crimes and only when you are caught by the Police (or your employer bothers to do a Criminal Records Bureau check) will they realise you had former convictions.

Surely this ECJ ruling has been taken too far? If it is allowed to go on, then we can no longer rely on Google to give us accurate web search results. In that case, maybe we should start using a different search engine that doesn't respect the ECJ ruling (or rather, is not afraid of being fined by it)?

If a web site is hosting some dubious content, and it is proved to be breaking the law, then the host site should be prosecuted not the search site - i.e. 'don't shoot the messenger'!
