E2B 1.56aBeta1 available

Still waiting for a bugfix in grub4os, but meanwhile I have added latest Beta to the Alternate Download areas.
For changes see here.
Let me know if you find any problems.

Bug in E2B 1.55 & 1.56beta (XP installs)

E2B v1.55 uses a version of grub4dos which has a bug. If you try to install XP from an ISO using DPMS, then XP Setup complains that it cannot detect any disks! This bug appears to start in grldr 2014-08-19 and later versions but is not in 2014-08-17 and earlier versions. I have reported this to chenall and hopefully he can find the problem.  If you have a later version, you can replace the \grdlr file with the 2014-08-17 version of 0.4.5c from http://grub4dos.chenall.net/categories/downloads/.

Please update to v1.55a or 1.56a.

Note: As of 2014-09-19 I am still having weird issues with grub4dos later versions (e.g. losing USB drive, not enumerating all items, hanging).

P.S. 20141027 and later seem OK.

Bug in E2B v1.56 (in grub4dos)

It seems something is broken in the new version of grub4dos!
If using XP Install and DPMS, you will get a FAT disk I/O error.
I have withdrawn v1.56 until chenall can fix grub4dos.
You can replace \grldr with the 2014-08-17 version if you like, but E2B v1.56 will complain about it being too old.

E2B v1.56 released

PLEASE NOTE: Discovered a bug in the new grub4dos version! I have withdrawn v1.56 until a grub4dos is fixed! Please use v1.55 for now.

Changes in 1.56

• New grub4dos \grldr (20140908) fixes exFAT bug with >4GB files + other small bugs
• CPU 32/64 bit & Total memory displayed in Main Menu heading and Windows Install menu
• New Sample mnu Files examples. 
• Weird characters such as ()!''&| may now work if used in Windows ISO and .imgPTN filenames.
• 'Boot any key to boot from CD or DVD' Windows install prompt suppressed. 
• Default Aurora background compressed using lzma (reduced size). 
• .iso64 family of file extensions recognised (only listed if 64-bit CPU). 
• Fastload menu has changed (only seen if FASTLOAD is enabled) - now press F8 to refresh the menu instead of the separate REFRESH entry. 
• Change Automn.g4b and Automn.g4b to use 56MB area of memory instead of 74MB area so can use E2B on systems with 64MB of memory or more.

Let me know if you spot any problems. The F1.cfg Help menu is in English in all languages and also some of the new text in STRINGS.txt (see end of file). Any translations welcome!

Easy2Boot v1.56Beta10 now available for testing

E2B v1.56 Beta10 is now available in the Alternate Download area on the Easy2Boot Download page here. I consider this to be a Release Candidate and will release it as the official v1.56 soon unless anyone spots any bugs. It uses the latest versions of grub4dos which have several new minor bug fixes thanks to Chenall. The E2B version history is here.

To update your E2B drive, just extract all files from the zip file directly onto your E2B USB drive (even if you have the DPMS version on your E2B USB drive, it will still be updated correctly).

P.S. I have updated RMPrepUSB to include the same new version of grub4dos too. Download from here.

How to make your own linux ISO .mnu files

I was asked today about LXLE with persistence. This distro is based on Lubuntu and the user wanted to get persistence working. There was a lubuntu-13.04-desktop-i386_Persistent.mnu menu available but not one for LXLE.

I thought I would describe how I went about changing this lubuntu-13.04-desktop-i386_Persistent.mnu file to get it working with LXLE.

• First I copied the lubuntu-13.04-desktop-i386_Persistent.mnu file and the lxle ISO file to the \_ISO\MAINMENU\MNU folder of my E2B NTFS USB drive which I use for testing.
• Next, I renamed the file to lxle-1404-x64_Persistent.mnu.
• Next, I edited the .mnu file in Notepad to change all occurrences of the  lubuntu-13.04-desktop-i386.iso file to lxle-1404-x64.iso.
• Next, I changed all occurrences of the persistent file lubuntu-rw to lxle-rw
• Finally, I made a persistent ext2 file in the root of the E2B USB drive using RMPartUSB's - Create ext2 FS button. When prompted I used:

               File Name = lxle-rw
               Volume Name = casper-rw
               Size = 500

• I then ran WinContig on the drive (RMPrepUSB - Ctrl+F2).

Unfortunately, I got an error when I tried to boot from the menu entry in E2B

This indicated that the file \casper\initrd.lz was not actually present inside the .iso file.

Looking inside the ISO file using 7Zip to view it, I found:

Normally, in a linux ISO that uses isolinux to boot, there is an isolinux folder which holds several .cfg files, the main one being isolinux.cfg. If grub is used, there may be a \grub folder containing config files. If grub4dos is used, it may have a \menu.lst file and other .lst files.

I double-clicked isolinux.cfg to open it up in Notepad ++ (if you try to use Windows NotePad, it will merge all the lines together due to a CR/LF problem - see below).

The isolinux.cfg main LiveCD menu entry seems to be:

label live

  menu label live - boot the Live System

  kernel /casper/vmlinuz

  append  file=/cdrom/preseed/custom.seed boot=casper initrd=/casper/initrd.gz quiet splash --

So I converted this to grub4dos as follows:

kernel /casper/vmlinuz file=/cdrom/preseed/custom.seed boot=casper persistent quiet splash --

initrd /casper/initrd.gz 

As you can see, we just need to re-arrange a few things. The reason for the error is now apparent, because the file used for the initial ramdrive (initrd) is initrd.gz and not initrd.lz as it was in the Lubuntu .mnu file.

Warning: Do NOT copy and paste whole lines from a linux .cfg file into a grub4dos .mnu file. The carriage-return/line-feed end-of line characters are not the same in a linux file and although it may look OK in NotePad, it won't work in grub4dos due to embedded invisible CR/LF characters! It is better to type them in manually rather than copy and paste in lines from a linux text file!

We need to add in the 'persistent' parameter so that it will look for a casper-rw volume when it boots.

In the end, after tidying up the .mnu file a bit to make it easier to modify for the end user, we have:

# Make a ext2 file using latest version of RMPrepUSB in the root of the drive 

# File Name=lxle-rw  Volume Name=casper-rw

# Place this .mnu file and the ISO in either \_ISO\MainMenu\MNU or \_ISO\Linux\MNU

# This menu will work even on an NTFS USB boot drive

# IMPORTANT: you MUST run WinContig (Ctrl+F2) before booting E2B.

# e.g.

#\lxle-rw

#\_ISO\MAINMENU\MNU\lxle-1404-64.iso

#\_ISO\MAINMENU\MNU\lxle-1404-64_Persistent.mnu

This .mnu file will be in the Sample mnu Files folder in the next E2B 1.56Beta download and is also in the Alternate Download area now (though it may be removed later when 1.56 is released).

E2B v1.56Beta9 available

Stephan has emailed me with some suggestions on improving E2B when using FASTLOAD.

As you may know, if you enable FASTLOAD by simply copying the \_ISO\FASTLOAD.YES file to the root of your E2B USB drive, it causes the Main Menu to be cached the first time you boot to E2B. The next time you boot to E2B, it will not need to enumerate all the files in the \_ISO\MAINMENU folder + sub-folders, but will just load the cached menu that was made during the previous boot. This can speed up the appearance of the E2B Main Menu if you have a slow USB drive and lots of files in your \_ISO\MAINMENU folder.

The main changes affect the following files:

\_ISO\e2b\grub\MENU.lst  - small changes to improve messages and set STALE variable
\_ISO\e2b\grub\E2B.cfg  - small text changes

\_ISO\e2b\grub\ENG\STRINGS.txt - new strings $$STRmFS1, $$STRhMFD and $$STRhMFE

\_ISO\MAINMENU\ZZZF8ReloadMenu.mnu - modified to also refresh the cached FASTLOAD menu
\_ISO\MAINMENU\ZZA_FASTLOAD_ON_OFF.mnu - If FASTLOAD is active, this new menu entry will allow the user to enable or disable it. This menu entry can be suppressed using set NOFLDMNU=1 in your \_ISO\MyE2B.cfg file
\_ISO\MAINMENU\ZZZF8$_SHOW_FASTLOAD.mnu - new file to display a non-operational menu entry just above the F8 menu entry which shows the user that they are using a cached (old) menu.

You can, of course, delete any of these .mnu files and/or make a new version to modify their action or appearance (just don't use the same filename as E2B uses or they will be overwritten the next time you update!). You can also make your own STRINGS.txt file to modify the menu entry text.

The new Enable\Disable FASTLOAD menu entry can be suppressed by using the NOFLDMNU variable in your \_ISO\MyE2B.cfg file if you don't want the user to be able to disable it. Alternatively, you can just delete the ZZA_FASTLOAD_ON_OFF.mnu file.

If the \FASTLOAD.YES file is not present, then the Main menu will appear just as it did before.
If the \FASTLOAD.YES file is present, then you will see the Main menu below:

FASTLOAD ENABLED - Menu was loaded from cache on booting.

Note the 'CACHED MENU (FASTLOAD)' warning is displayed in the menu.

FASTLOAD ENABLED - Menu was just Refreshed by user using F8.

FASTLOAD DISABLED - it can be enabled again by the user with '3 Enable FASTLOAD'.

Let me know if you like this new arrangement or not.

I am still waiting for a few more bugfixes in grub4dos before I release v1.56. Chenall is working hard on the fixes and it should be done in a day or so.

Tiny PXE Server tryout

I had seen Erwans Tiny PXE Server app but tonight I decided to try it out.

I wanted to just boot a WinPE ISO file via PXE as I thought this would be the easiest to get going.

Documentation for getting started is not that well organised on reboot.pro or in his Blog.
I eventually found a Blog post here for booting PE.

Here are step-by-step instructions for how I did it:

1. On My Windows 8.1 x64 PC, I downloaded Tiny PXE Server from reboot.pro (check the download link in this post)

2. I extracted the files to C:\temp\pxesrv on my Windows system

3. I copied a WinPE_x86.ISO file that I had lying around to the C:\temp\pxesrv\files folder.

4. I used NotePad to create a winpe.ipxe text file in the C:\temp\pxesrv\files folder as below:

#!ipxe
dhcp net0
set boot-url http://${dhcp-server}
initrd ${boot-url}/images/WinPE_x86.ISO
kernel ${boot-url}/memdisk iso raw
boot

5. Next I ran the C:\temp\pxesrv\pxesrv.exe file and changed a few settings as show in the red boxes below:

Note that I needed to choose a DHCP server address of 192.168.1.xx to match the subnet address of the router.

The Extra Option also needed to be set to 175.6.1.1.1.8.1.1  -> vendor option is 175.6.1.1.1.8.1.1 (etherboot length 6 code 1 length 1 value 1 code 8 length 1 value 1). More details here http://www.etherboot.org/wiki/dhcpd

When you are happy with the settings - click the Online button.

6. Finally, I connected an Ethernet cable from my router to my EeePC 904HA netbook, switched it on and selected 'Network Boot' from the BIOS Boot menu.. VIOLA! - it started to load the ISO into memory and then booted to it! The EeePC now runs WinFE via PXE boot.

I have not yet experimented any further with Tiny PXE Server, but so far it looks encouraging!

Erwan has more examples on his Blog here and some quick HowTo's are here for different payloads.

Tip: If you are having problems PXE booting from a real system, it may be due to your router or client system. A good test is to run a Virtual Box virtual machine. Just set the Network adapter to 'Bridged' - start the VM - press F12 and then L for Lan. It should then PXE boot. This tends to bypass your router + cable + client and often works when a real system does not!

PassPass for Win8.1 (32-bit and 64-bit)

Add PassPass to your E2B USB drive and get access to any Windows system without needing to know the user account password!

I fixed the issue with 32-bit 8.1 and now the PassPass20140902SS.zip version 1.5 should patch XP -> Win8.1. Not tested on Win8.1 Update (but dll for 64-bit looks same as Win8.1 so hopefully will work).
I suggest you test on a 'test' system and not your work/office/home system (or at least make a backup first!).

Note: Latest version (same filename!) is listed in the E2B menu as (PassPass E2B v1.6) - if yours does not say this please download latest version. The E2B PassPass download is available in the Alternate Download areas from this page.

PassPass update for Win 8.1/10

I have updated the clever PassPass grub4dos utility written by Holmes.Sherlock and Wonko the Sane from reboot.pro. It should now work for XP through to Windows 8.1.

Note: Latest version in E2B v1.87+ includes PassPass v1.7 for XP through to Win10.

This utility allows you to bypass the Windows user password required for logging into a  local user account on Windows (does not work if you select an online Microsoft account, so select a local user account first). It works by hard-patching a Windows dll file before you boot to Windows. Once you have finished with the Windows system, you can Unpatch or restore the dll so that normal password function is restored.

Note: KonBoot v2.5 will allow you to get into a local user account or online account in Win8/8.1/10.

For more details on PassPass, see here.  It allows you to gain access without using the user's account password, PIN number or picture gestures (just use any password, PIN or gesture!).

Add PassPass to E2B

PassPass can be found in the \_ISO\docs\PassPass folder on your E2B drive with a ReadMe.txt file or you can unzip the downloaded E2B PassPass version.

1. Copy the PassPass folder to your E2B USB drive  (e.g. to \_ISO\UTILITIES\PassPass). 
2. Then move the large PassPass.bak file to the root of the E2B USB drive - for example:

\_ISO\MAINMENU\UTILITIES\PassPass\PassPass.mnu
\_ISO\MAINMENU\UTILITIES\PassPass\PPass.g4b
\_ISO\MAINMENU\UTILITIES\PassPass\wenv
\PassPass.bak

I would advise you to test it first on a 'test' system and NOT on a system that you need (or at least take a full backup first). The file \Windows\system32\msv1_0.dll is the only Windows file altered by PassPass.

PassPass menu entry

PassPass will detect all Windows installations on all disks

Choose which one you want to patch.

You can backup the msv1_0.dll file first before you patch it.

Then run the Patch Windows menu option.

You will be told how many patch areas have been identified.

Press ENTER to patch the dll and then choose the Boot from Internal Hdd menu option

to boot to the patched OS (or reboot the system).

To change a User Account password once patched with PassPass,

1. Create a new Administrator User Account (e.g. NEWUSER) with no password
2. Log-in as NEWUSER. 
3. You can then change the password on any other user account. 
4. Then delete the NEWUSER account and restore the DLL by running PassPass again.

P.S. If you try PassPass and it worked, please tick the 'funny' box below. If it failed, please add a comment and give details of the msv1_0.dll file in your version of Windows (click on Properties).

PassPass for WinPE

If you need to patch a system that is UEFI-bootable only, you can boot to WinPE and run the Windows PE executable version PEPassPass.exe.

E2B UtilMan and SetHC  hack feature

E2B v1.92+ also contains a useful automated way to use the UtilMan.exe hack for Windows XP-10 which works on all (unencrypted) Windows OS's.

E2B v1.56 now recognises .iso64 file extensions

E2B v1.56 Beta6 and later versions will now recognise the .iso64xxxxx file extension and will only list the ISO in the menu if the system contains a 64-bit CPU.

This means that if you boot from a 32-bit CPU, you will not see the menu entries for any 64-bit ISOs if you simply use a .iso64 file extension for them.

Note that this does NOT apply to ISOs under the \_ISO\WINDOWS folder (the Windows Installler ISOs) - for these you must use the .ISO file extension.

Most of the .iso family are supported - e.g. .iso64, .iso64PE, .iso64PE01, .iso64mem, .iso64win, .iso64linux, .iso64grub, .iso64force, .iso6401, .iso64dd, .iso64gz, .iso64e0, .iso64meme0,  .iso64pup and .iso64WB.

You can prevent all the file extensions from being listed in the menus by using  set EXTOFF=1  in your \_ISO\MyE2B.cfg file.

Note: If your menu uses FASTLOAD, you do not need to Refresh the menu when you boot on a different 32/64 bit system. The menu will test for a 32-bit or 64-bit CPU each time it is loaded.



A nice-sounding lady telephoned me yesterday and asked me if  I would like sign up to go on a Meditation Course - I told her I would think about it...

Adding Unattend.xml files to Windows 7/8 Install UEFI .imgPTN images in E2B

If you want to install Windows Vista/7/8 etc. in MBR\CSM mode, you can just copy the Windows Installer ISO to the correct E2B USB folder, and you can copy over your own Unattend.xml files to the same E2B folder. E2B will then allow you to pick any one of these XML files so that the Windows install uses the correct Product Key (which is required by Win8), or is semi-automated or even full-automated, depending on what is in your Unattend.xml file.

However, if you use MakePartImage to convert the Windows Installer ISO into a partition image (.imgPTN file) so that you can both  UEFI- and MBR\CSM-boot from it, you will not have any of the E2B features to choose your own XML file or automate the install.

I have therefore detailed some instructions here on how to add your own AutoUnattend.xml file to a partition image .imgPTN file.

If you are using an E2B Removable type of USB Flash drive, then you just need to copy the AutoUnattend.xml file to the root of the image. However, if your E2B USB drive is a Hard disk or 'Fixed disk' type, then this will not work because Windows only auto-detects a \AutoUnattend.xml file on removable media like Flash drives, floppy disks (remember those?) or DVDs.

Instead we need to tweak the files inside the \sources\boot.wim file.

If you follow the instructions, you can even offer the user a choice of XML files to use before Windows Setup runs.

Detect a 64-bit or 32-bit CPU in Easy2Boot

We can use grub4dos to detect the CPU bitness using the is64bit command.

E2B v1.56 Main  menu heading shows CPU type and total usable system memory

We can use this to make a .mnu file for the MAINMENU folder:

$$$CPU_TYPE.mnu
===============
# Display as menu item if CPU is 32-bit or 64-bit

iftitle [checkrange 2,3 is64bit]   --- INFORMATION: 64-bit CPU ---
errorcheck off


iftitle [checkrange 0,1 is64bit]   --- INFORMATION: 32-bit CPU ---
errorcheck off


To make a menu entry that will allow the user to check it use:

title Check the Processor\n Detect if CPU is 32-bit or 64-bit

checkrange 2,3 is64bit && pause Processor is 64-bit
checkrange 0,1 is64bit && pause Processor is 32-bit

errorcheck off

boot

The 64Bit_Auto_Detect_ISO.mnu file in the E2B Sample mnu folder has an example where either a 32-bit or 64-bit ISO will be automatically run depending on the system CPU:

# Change the 1st, 2nd and 3rd line as required - line 4 may be deleted if no pause required

title Run a 32-bit or 64-bit linux ISO \n Auto-Detect system type and run correct ISO

set ISO=Ubuntu32.iso

checkrange 2,3 is64bit && set ISO=Ubuntu64.iso

pause WILL BOOT %ISO% - Press ENTER key to continue...

/%grub%/qrun.g4b $HOME$/%ISO%

boot

To make a .mnu file for a 64-bit ISO that will only be visible if the system has a 64-bit CPU, we can use:

iftitle [if exist $HOME$/Ubuntu64.iso && checkrange 2,3 is64bit] Ubuntu 64-bit \n Boot from a 64-bit ISO

/%grub%/qrun.g4b $HOME$/Ubuntu64.iso

boot

E2B v1.56 Beta available

A number of people have hit the problem of using Windows Install ISOs which have non-standard characters in the ISO filename, such as ( and ) and ! and & etc. This caused a problem with some of the Windows .cmd scripts which are automatically run when Windows\WinPE boots.

I have attempted to fix this now in v1.56Beta, so you can have names like:

Windows 8.1 32-bit & 64-bit (English).iso

also, I have found a way to suppress the 'Press any key to boot from CD or DVD' prompt which you may see when you boot from some Windows ISOs. This message is caused by the \boot\bootfix.bin file inside the ISO file. If the bootfix.bin file is not present then the code inside it which prompts you to press a key is not run. I found a neat way to prevent this from being run - see here for details.

Please let me know if you find any issues with this Beta version.

Easy2Boot v1.55 released (at last!)

Quite a few changes in version 1.55, thanks to many others for ideas, improvements, language files and bug reports!

E2B v1.55 changes:

• F1 Help Main menu added (English only). F1.cfg help file can be translated into other languages.
• \_ISO\e2b\grub\menu.lst code change to work around incompatibility issue between AMI BIOSes and MyDigitalSSD OTG USB drive - grub4dos losing all variables! Affects HP Compaq dx2400 microtower, Asus M4A89GTDPRO-USB3 motherboard, Asus x550ca - all have American MegaTrends BIOS. Exact cause still under investigation.
• Portuguese language STRINGS.txt added (thanks Carlos).
• Romanian language STRINGS.txt added (thanks Anto).
• French language STRINGS.txt added (thanks Nicolas).
• New \_ISO\docs\mythemes folder added - supports adding a $Change_Theme.mnu menu file to the Main menu. Read the ReadMe.txt file in the folder for more info.
• .cfg file extension support added - can now switch themes by copying a MyE2B.cfg-style file to a menu folder.
• \_ISO\docs\Sample E2B Templates folder name changed to Templates due to path length limitations in grub4dos. If updating, you can delete the old Sample E2B Templates folder.
• Latest grub4dos grldr versions included in E2B (important long-standing NTFS bug fixed in new version). Longer paths allowed for splashimage, etc. see http://grub4dos.chenall.net/categories/downloads/ for details of fixes.
• EXTOFF variable added for MyE2B.cfg file - if set to 1, file names are listed in the menu without their file extension.
• Various small changes to Qrun.g4b, English STRINGS.txt and other E2B files.
• You can change or remove the menu  ► arrow marker symbol which indicates the highlighted menu entry, using a new grub4dos feature (see Sample_MyE2B.cfg).
• If you prematurely abort an .imgPTN file selection, the 4th partition is now cleared instead of leaving it switched in.
• Sample_MyE2B.cfg has sample code to detect host display resolution and choose different wallpapers.
• linux fmt.sh script revised so works with older bash shells (thanks Todd).

New files added to \_ISO\docs\Sample mnu Files folder:

• linuxmint-17-mate-32bit-v2_Persistent.mnu - for new versions of Mint
• Tails_for_USB_HDD_Persistent.mnu - required if running Tails from a USB HDD or if you want persistence
• Change_Wallpaper.mnu - allows user to change the wallpaper background from a menu entry
• Change_Language.mnu - menu entry to change E2B language
• Change_Theme.mnu - menu entry to allow user to select a theme
• BlueTheme.mnu  - example of how user can select an alternate Theme template
• Desinfect_2014_Peristent.mnu
• Desinfect_2014_with_Updates.mnu
• A_BlankMenuEntrySeparator.mnu - fancy 3-line separator
• Win_Vista_7_2K8R2_Direct.mnu - for Win install menu entry with preset XML file
• Win_Win8_2012_Direct.mnu - for Win install menu entry with preset XML file and/or KEY
• PTN_LOG1_Menu.mnu - If you have an E2B drive with a Logical partition, you can boot from files on that partition with this menu.

As always, let me know if you find any problems - there are many 1000's of happy E2B users who don't have a problem, so if you do find a problem ,it will probably be due to an incompatibility with your particular system or payload file. Many of these sorts of problems can be worked-around or fixed, but only if you let me know using the Contact Me page on the www.easy2boot.com website!

Let me know what you think of the new changes.

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

A problem with a wireless mouse and USB 3.0 flash drives was driving me crazy!

If you have read my blog, you may remember that I had built a new system a few months ago - see here.

On the whole I have been very pleased with the system. It is quiet and fast.

The front panel has four USB ports, the top two are USB 2.0 and the bottom two are USB 3.0.
I specifically wanted this Cooler Master N600 case so that I could have convenient access to both types of ports.

I needed easy access because, of course, I need to test Easy2Boot USB drives a lot!

The only problem that I have been having for months now was with the Anker Wireless Mouse and dongle that I had plugged into one of  the front panel USB 2.0 ports of my new PC.

Most of the time the mouse+dongle worked just great, but I noticed that whenever I plugged in a USB 3.0 Flash drive into the USB 3.0 port on the front panel, the wireless mouse started to respond in an unreliable and jerky fashion, particularly just after the USB 3.0 Flash drive had been connected (and Windows would start to access\scan it).

If left it for a few minutes, the wireless mouse response would improve slightly, but it still gave me trouble (I humbly apologise for any physical harm that I may have caused to the poor, long-suffering creature and I also apologise for any abusive comments that I may have shouted at it in sheer frustration whenever the cursor started to behave erratically)!

My first thought was that perhaps the single AA battery in the mouse was getting flat, but I found that if I changed it for a new one every week, the response did seem to improve slightly, however it still wasn't perfect and it soon started to play up again.

As always, as soon as I unplugged the USB 3.0 Flash drive - the mouse responded perfectly!

I tried many different USB drives and found that:

1. The issue only occurred with USB 3.0 Flash drives  (not external USB 3.0 hard disks which, of course, had a short USB 3.0 lead)
2. The issue only occurred when I connected a USB 3.0 flash drive to the USB 3.0 front port - if I connected the same flash drive to the other spare USB 2.0 front port or rear USB 3.0 port - no problem!
3. If I connected a USB 2.0 Flash drive to a front USB 3.0 port there was no problem.
4. There was no difference in behaviour, whether I connected the USB 2.0 wireless dongle to the front USB 3.0 port or to the front USB 2.0 port.
5. If I replaced the wireless dongle with an ordinary wired USB 2.0 mouse it worked fine.
6. The wireless dongle worked in the rear USB ports (but this was inconvenient if I wanted to use the dongle in another system, because I could not easily get access to the rear of the PC to remove it).

Over the last few months, I have tried updating the USB chipset drivers of my Haswell mainboard but to no avail.

Today however, I Googled for 'USB 3.0 wireless mouse jerky' and found this thread.

It said that USB 3.0 signals can cause interference with the 2.4GHz wireless mouse dongle and that I should separate the USB 3.0 flash drive from the USB 2.0 wireless Bluetooth dongle. It cited an Intel PDF on the subject here (esp. see 4.3).

So I got out a spare, well-shielded USB 2.0 extension cable and used it to connect the wireless dongle to the same USB 2.0 front port as before.

           

Fig. 1   Before (mouse was jerky)    - and -     Fig.2  After (works perfectly)!

The result was  (drumroll......)   >>>   the wireless mouse now works fine!

Even if I taped the wireless dongle directly on top of the USB 3.0 Flash drive it still worked without any problems! This suggests to me that Intel's assumption that the problem was caused by radiated interference is not correct. It seems to me that the problem is caused by electrically transmitted noise.

Another test was to completely wrap the USB 3.0 Flash drive in tin foil and earth the foil to prevent any wireless interference (without using an extension cable). Again this proved ineffective.

I also tried inserting a 1m USB 3.0 extension cable between the Corsair GT USB 3.0 Flash drive and the front panel USB 3.0 port with the wireless dongle directly plugged into the USB 2.0 port  (i.e. as in Fig.1 but using a USB 3.0 cable to connect the Flash drive). I deliberately placed the flash drive on top of the wireless dongle so it would cause maximum radiated interference - but again the mouse worked fine!

So it seems that merely using a USB extension cable fixes the problem - this may be because the RF frequencies in the USB 3 data lines or power lines are being absorbed by the USB cable's ground shield, so that less electrical RF noise get's back to the front panel PCB via the signal/data wires.

So I am not at all convinced that this is a case of wireless interference - more likely, it is a case of poor grounding and isolation on the USB port PCB that is inside the front panel of the case. It may be that a few high-frequency decoupling capacitors sprinkled around the USB port PCB may fix the problem, but I am going to leave that for another day! Getting rid of high-frequency noise such as 2.4GHz is tricky and often a multi-layer PCB with close ground-Vcc planes is the only way - this would mean Cooler Master would need to make a decent multilayer front panel PCB. Better grounding would also help!

Equally, there may be a lack of high-frequency decoupling inside the USB 3.0 Flash drives too (I tried 3 different makes and they all gave problems - Corsair Voyager GT 32GB, a Pretec Rex 100 8GB and a Busbi 16GB, the Busbi USB 3.0 Flash drive had a silver 'metalic-paint' plastic case and did not seem to cause quite as much of a problem as the other two). The PCBs inside these pen drives are often simple dual-layer PCBs.

Summary

So just bear in mind that if you have  USB 3.0 devices  AND wireless devices such as  wireless mouse dongles, bluetooth dongles or WiFi dongles (or perhaps TV tuner dongles) - keep all USB 3.0 devices away from them. If possible, use rear ports for one and front USB ports for the other.

If you are still having problems, try using short, well-shielded USB cables instead of connecting them directly to the system's USB ports.

If they ever start making USB 3.0 versions of wireless dongles - I can see this issue becoming a BIG problem!

P.S. Since sorting out this problem, I have noticed that the battery in my wireless mouse lasts for several months now instead of just a few weeks. My guess is that it had to keep re-transmitting 100's of bluetooth packets due to the interference problems and that this quickly depleted the battery.

Easy2Boot v1.55 can display files in the menu without their file extensions

Files in E2B menus are normally displayed by using their full  filename + extension, as below...

You can use a .txt file to define an alternate menu entry for each file.

However, now with v1.55, if you use  set EXTOFF=1 in the \_ISO\MyE2B.cfg file, all files in all menus will be displayed without their file extensions, as shown below...

You can use spaces in the filename if you wish (see #4).

A Beta7 version of 1.55 is available in the Alternate Downloads area as usual.

It is almost ready for release, I am just waiting for one bugfix to grub4dos 0.4.6a from the developers.
E2B v1.55 will complain if the latest version of grub4dos is not used. Although it may work using earlier versions of grub4dos, some bugs have been fixed recently in grub4dos (one of which was quite serious to do with writing to NTFS files not working), so a new version is 'required'.

Many thanks to the E2B users who have suggested small tweaks and improvements to make E2B even better!

The latest grub4dos also allows you to disable or change the ► symbol that is displayed at the side of the highlighted menu entry - see the \_ISO\Sample_MyE2B.cfg file for details.

P.S. MakePartImage has also been updated to v 0.037 and now includes RMPartUSB.exe in the \e2b folder so you can restore the E2B partition from Windows using the RestoreE2B.cmd script, without needing to boot from the E2B USB drive to the CSM menu.

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

Add Desinfect+Persistent Virus Updates to your Easy2Boot USB drive

Here are the steps to add the Desinfect 2014 (and 2015/2016/2017/2018/201819) ISO to you E2B USB drive and have persistent virus definition updates too ...

Add Desinfect 2014 + Persistence to your Easy2Boot multiboot USB drive

As with most ISO files, you can just add the Desinfect 2014 ISO file to your Easy2Boot USB drive and boot from it in BIOS/MBR mode - OR - you can drag-and-drop the ISO onto the MPI Toolkit FAT32 Windows Desktop icon to make a partition image file and then add the ct_desinfect_2014.imgPTN file to your Easy2Boot drive, if you want to 64-bit UEFI-boot to Desinfect as well as MBR-boot.

If you want to enable persistence however, you will need to use a special .mnu file as well as the Desinfect ISO file.

Adding a persistence ext2 file allows some Desktop settings to be remembered after a reboot. For instance, any files placed on the Desktop will be preserved. However, the background wallpaper is reset to the Desinfect wallpaper after every boot.

I also could not get the antivirus updates to be persistent using this method, they have to be downloaded each time you boot to Desinfect.

Note: You can have persistent updates, but not with persistence as well - see the next blog post!

Here is the .mnu file. The top lines are comment lines and contain instructions on how to add persistence. The .mnu file is also available in the Alternate Download Area from here.

# Make a \casper-rw ext2 file using RMPrepUSB in the root of the drive using RMPrepUSB
# File Name=desinfect-rw  Volume Name=casper-rw size=500MB or change as desired
# Place this .mnu file and the ISO in either \_ISO\MainMenu\MNU or \_ISO\LINUX\MNU
# This menu will work even on an NTFS USB boot drive
# IMPORTANT: you MUST run WinContig (Ctrl+F2) before booting E2B.

F1 Help function added to Easy2Boot v1.55

A user requested an F1 help hotkey feature, so I have added this into E2B v1.55.

There is a new .mnu file for the Help Main menu entry and the actual Help text (English only) is held in an F1.cfg file:

• \_ISO\MAINMENU\ZZZF1SubMenuHelp.mnu
• \_ISO\e2b\grub\ENG\F1.cfg

Help menu screen (F1.cfg)

Help text is displayed in the console screen.

It is expected that the user will want his own F1 menu, so all they have to do is copy the \_ISO\e2b\grub\ENG\F1.cfg file to the \_ISO folder and edit it to show whatever help text they want for their E2B payload files and hotkeys, etc.

If you do not want a Main menu entry, but you still want the F1 hotkey to work, then you can specify a generic F1 hotkey in the \_ISO\MyE2B.cfg file. The user can then press F1 in any E2B menu and they will see the Help menu and so no Main Menu entry is needed.

There is example code in the Sample_MyE2B.cfg file for this (just uncomment the 3 lines):

# Make the F1 key show the Help Menu from any menu (uncomment 3 lines below) - you can put your own help file in \_ISO\F1.cfg
###if exist /_ISO/F1.cfg   ()/%grub%/hotkey [F1] "configfile /_ISO/F1.cfg" > nul && goto :f1skp
###if exist /%grub%/%LANG%/F1.cfg ()/%grub%/hotkey [F1] "configfile /%grub%/%LANG%/F1.cfg" > nul && goto :f1skp
###if exist /%grub%/ENG/F1.cfg ()/%grub%/hotkey [F1] "configfile /%grub%/ENG/F1.cfg" > nul
:f1skp


The F1 Help menu can be removed from the MAIN Menu by deleting the file \_ISO\MAINMENU\ZZZF1SubMenuHelp.mnu (in later versions of E2B use 'set NOF1=1' in the \_ISO\MyE2B.cfg file).

V1.55_Beta3.zip is available from the Alternate Download links on the Easy2Boot Download page.
