Raspberry Pi 3 multiboot E2B USB drive (untested!)

I notice that the Raspberry Pi 3 can be made to boot from a USB storage device by setting a one-time programmable bit (see video here and blog article here).

The Raspberry Pi 4 does not yet have this capability, but it should be possible in the future.

I don't own a Pi 3, but looking at the Raspbian download .img file, it contains two MBR-partitions, a FAT32 boot partition and a ext partition. This means it should be possible to boot a Raspberry Pi 3 (and later on, a Pi 4) from any .imgPTN file on an Easy2Boot drive. So you could have multiple Pi .imgPTN files all on one E2B USB drive.

I am unsure if it also makes a swap partition and if it does, how it makes the swap partition, so this process may totally corrupt your E2B drive. For this reason I suggest that you test it on a spare E2B USB drive first. Please let me know if you feel like experimenting but don't use your E2B drive if it contains any wanted files! It would be cool to have multiple Pi images on one E2B USB drive.

How to find any file in seconds (no Indexing needed)!

How many times a day do you spend ages looking for a file that you know is on a drive in your system somewhere, but you just can't remember where you put it?

Well, SwiftSearch (use latest version which is currently v7.5) is a portable, standalone Windows program on SourceForge that will find your file(s) in seconds as long as it is on an NTFS volume. It does this by directly accessing the $MFT (directory) on each NTFS volume in your system and it's really quick!

I use this utility about 20 times every day and have it pinned to my taskbar!

How to extract the hidden contents in 'special' ISOs and images using 7Zip

7Zip is pretty good at opening ISOs and other files. However, sometimes you may find that it does not expand the contents correctly.

I learned recently of a way to use 7Zip to reveal these 'secret' files.

Easy2Boot v1.B2 and MPI Tool Kit v0.096 now released

E2B v1.B2 and MPI Tool Kit v0.096 are now available from the 1Drive and Box download areas.

I will update the main web site and the FossHub site in a few days.

Changes for E2B are as detailed in previous blog.

Read eBook #1 for details on how to remove the blue E2B startup banner screen (or contact me for details if you have already made a donation).

Changes from MPI Tool Kit v0.095 to 0.096 are:

• Add Czech language for CSM menu
• Add latest E2B_Editor.exe to MPI folder
• KBD variable can now be used to set KBD type
• Update grub4dos (\grldr file)
• Add all KBD translation files.

The MPI CSM Legacy menu now supports English, German, Hungarian and Czech. To use a non-English menu, create a MyCSM.cfg file in the .\CUSTOM folder and set the LANG and KBD variables.

Please update your E2B drives and let me know if you spot any problem. You can easily downgrade to a previous version of E2B very quickly if required.

Latest E2B v1.B2e Beta with bugfix for some Acronis ISOs hanging

Some bugs have been found and fixed in grub4dos.

The most serious for users is that a few Acronis ISOs seem to hang when using the previous version of grub4dos.

Changes from released version v1.B1 are (v1.B2e changes in red):

• Bugfix: grub4dos hangs when booting some Acronis ISOs.
• Bugfix: grub4dos blue\black color setting causes green background
• New feature: %MEMSIZE% and %BITNESS% variables can now be used in HEADING and HELPTEXT or anywhere inside MyE2B.cfg (e.g. 2028 64)
• Add Slovenian language files and Croat\Slov kbd file added (thanks to Peter K).
• Add Turkish language and kbd (thanks to Tayfun)
• Add improved Czech language files (thanks to Pepa) and new Czech kbd files
• Bugfix for switching to .imgPTN after ptn2/ptn1 switched over using RMPrepUSB-Ctrl-O-2.
• Improve ISO's VOL and UUID which are displayed below menu area
• Improve E2B_Editor.exe for MyCSM.cfg editing (will add language and kbd from a .imgPTN USB drive)
• Improve change kbd and change wallpaper .mnu menu files
• Change QEMU to use standard VGA graphics ROM instead of cirrus logic graphics ROM
• Tweaks to \_ISO\e2b\grub\menu.lst
• Updated Make_E2B.exe

http://rmprepusb.blogspot.com/p/e2b-alternate-download-areas.html - see Latest Betas folder.

v1.B2e1 - bugfix in countfiles.g4b now works even if user has deleted any of the Windows sub-folders.

I hope to release this version soon, so let me know if you spot a problem.

Adding UEFI-bootable Lenovo BIOS updates to E2B

The Lenovo BIOS updates are typically either in .iso form or you can download their executable Windows BIOS Update (Flash from operating system version) utility and run it under Windows or WinPE (not all WinPEs will work, choose one with WoW64 such as Strelec or Bob Omb's WinPE).

If a UEFI .ISO update file (not a BIOS update ISO) is provided, you can convert this to a FAT32 .imgPTN file in the usual way. See here.

Sometimes a .zip file is provided. This can be drag-and-dropped onto the MPI_FAT32 Desktop shortcut to make a FAT32 .imgPTN file.

After making a .imgPTN file, always check that it contains a \EFI\BOOT\BOOTX64.EFI file - if not, then it is not going to UEFI64 boot (check by opening the .imgPTN file using 7Zip).

Method 1 uses the ISO, Method 2 uses the utility which makes a bootable flash drive (but we use it to make a .imgPTN file instead)...

New 'superspeed' download site for E2B and RMPrepUSB

FossHub now (today!) are hosting the stable release versions of E2B and RMPrepUSB.

Their servers are superfast too, so I hope to use them as the Primary source for downloads if all goes well.

Please try them out and let me know if you have any issues...

FossHub - Easy2Boot and MPI Tool Pack (superfast download for main releases only)
FossHub - RMPrepUSB (superfast download for main releases only)

Adding UEFI-booting of pfSense 2.4 to E2B

I have updated the blog article here (see end of the article) on how to convert the pfSense 2.4 version so that you can UEFI-boot from it to install it pfSense.

You do however need to MBR-boot to switch in the imgPTN file first (you cannot just use Switch_E2B.exe and then UEFI-boot).

E2B v1.B2d Beta available

How to remove the new E2B Banner

Make your PC scream when you unplug a USB device!

A recent Hack 5 video detailed a USB Rubber Ducky prank which is rather amusing.

The Rubber Ducky code downloads a scream.wav file and sets the sound file as the 'USB unplug' sound in your registry instead of the usual Windows default sound.

This means that whenever you unplug a USB device (of any type even if its a Bluetooth dongle and even if you first safely remove it or eject it) you will hear your PC scream!

Here is a Windows script which will allow you to set this up without a Rubber Ducky. You can also undo the Registry change too.

The script downloads the scream.wav file from the Hak5 site and it uses the built-in Windows utility 'bitsadmin.exe' to download the file. I was not aware of this Windows utility before. It looks quite useful, however it is much slower than a utility such as wget.exe.

P.S. If you want a different sound, find the file scream.wav on your hard drive (usually at C:\Users\(yourname)) and replace it with a different wave file of the same name (e.g. Woman Screaming).

If you are having problems downloading the file, just place any wave file named scream.wav in your user folder and then run scream.cmd.

grub4dos and non-USA keyboards

Together with Knyght, we have been working on supporting the Hungarian language and Hungarian keyboard for E2B.

E2B v1.B1c Beta includes the latest grub4dos version which adds even more Alt+ key support.

E2B uses grub4dos which, in turn, uses the BIOS to receive key codes from the keyboard. Unlike grub2, it does not have it's own keyboard interrupt handler.

A Hungarian 102-key keyboard produces the same keyboard scan codes as a USA 102-key keyboard or any other 102-key keyboard, the only difference is the engraved letters on the key tops.

This means that grub4dos must 'convert' the keyboard code it receives to generate the same character that is engraved on the key tops. For instance, when the key labelled " on a UK keyboard is pressed (shift+2), it should produce the " character and not the @ character that you would see if the keys had USA keyboard key tops.

grub4dos allows us to 'map' key codes using the setkey command. For instance, E2B uses a batch file to run a series of setkey commands to convert USA key codes to UK key codes:

E2B v1.B1b Beta available

This new Beta version v1.B1b Beta includes the latest version of grub4dos which has enhanced keyboard support for non-QWERTY keyboards.

Changes in v1.B1b are:

• Add menu text "(x present)" for number of XP ISOs present in Windows Install menu.
• New grub4dos setkey command now supports oem102 and Alt+ key chord scancodes.
• Small changes to Hungarian language files.

v1.B1a had these changes:

• Add Hungarian language and keyboard support (thanks to Knyght).
• If the Windows Install ISO filename contains the string 'WimBoot' (not case sensitive) then E2B will not use WIMBOOT to boot the ISO (you must use a Removable USB drive or use a WinHelper Flash drive) - e.g. Win10 Home and Pro x64 1809 Oct English International (NoWimboot).iso

Hungarian keyboard AltGr codes

On the Hungarian keyboard, some of the standard English ASCII characters are produced by using the AltGr key plus a letter or number key (the AltGr key generates a Alt+Ctrl key code).

For instance, the Hungarian keyboard is engraved so that the user expects AltGr+v to generate the @ symbol.

A Removable-type USB HDD enclosure (+ UEFI-booting from ISOs on a IODD\Zalman drive enclosure)

With the new addition of WIMBOOT to E2B, you now rarely need to use a 'Removable' type of USB drive for E2B.

However, in a few cases where WIMBOOT cannot be used (low RAM or incompatible ISO) then Easy2Boot works better from a 'Removable' type of USB drive (such as most USB flash drives) or if you also connect a small WinHelper USB flash drive to the target system as well as the E2B HDD drive.

A user recently contacted me via the online Chat feature on the E2B website and mentioned that his USB HDD enclosure appeared as a 'Removable' device. He was from Dubai and had purchased a cheap Haysenser USB 3.0 HDD enclosure from his local market.

E2B v1.B1a Beta available with Hungarian language support

v1.B1a changes (download here in Latest Beta folder)

• Add Hungarian language and keyboard support (thanks to Knyght).
• If the Windows Install ISO filename contains string 'WimBoot' (not case sensitive) then E2B will not use WIMBOOT to boot the ISO (you must use a Removable USB drive or use a WinHelper Flash drive) - e.g. Win10 Home and Pro x64 1809 Oct English International (NoWimboot).iso

Knyght has kindly done a lot of work translating the E2B language files to Hungarian. There will also be a translation file for the MPI CSM menu too!

Keyboard support

This proved quite challenging because the Hungarian keyboard is not supported very well in grub4dos.

Dell 'No boot device found.' error after installing Windows 10?

It seems that newer UEFI BIOSes from Dell now prevent you from MBR-booting from the internal hard disk (e.g. SATA, PCIe NVMe or M.2). However, you can still configure the BIOS to MBR-boot from external boot devices such as USB drives.

Details can be found on Dell Support link.

So, you can boot to the E2B grub4dos MBR boot menu (or MBR boot from a Rufus or other MBR USB drive) and install Windows 10 to the internal hard disk, however, when you reboot from the internal hard disk, you will see a 'No boot device found' error because the BIOS will only allow you to boot via UEFI from internal disks.

It seems that some of these Dell BIOSes were strictly UEFI-only at first, but then Dell released newer versions of the BIOS which included the 'Legacy External Devices' option. So you may need to update the BIOS if your current Dell BIOS does not have this option.

I suspect Dell later realised that a lot of their support utilities which relied on booting from USB or PXE only worked in MBR mode and so had to add this BIOS option!

Disclaimer: I don't actually have one of these systems to experiment with, so this information is just gleaned from the linked articles.

E2B v1.B0A update released

You may encounter an issue in v1.B0 where it reports an error or pauses for you to press ENTER before the Main Menu is loaded.

v1.B0A fixes this issue - please update from v1.B0.

Apart from this bugfix, you may also notice that the E2B drive icon in Explorer has changed (depending on if your system has cached thumbnails or not).

Note: Version 1.B0A still reports itself as v1.B0 in the menu heading.

Windows 10 May 2019 Update fails with "This PC can't be upgraded to Windows 10" error

The latest Windows update problem from MS!

The solution apparently is to remove your USB drives and SD cards!

E2B v1.B0 and MPI Tool Pack v0.039 now released

Available from Alternate Download areas here.

New eBook on UEFI multi-booting using WinPE images here.

E2B v1.B0 changes:

New first draft eBook available - 'How to make a UEFI multi-boot Easy2Boot USB drive'

The first draft is available and I have also made available some large files which go with the eBook.

It details how you can set up your E2B drive for UEFI multi-booting.

Details of how to obtain the password-protected download files are within the eBook.

The first draft is available for $10 (but you can pay more if you like!) at Payhip.

If you would like to volunteer to work through most of this eBook and Exercises and send me feedback, please email me and I can provide you with a 100% discount voucher (i.e. it's free! - first 20 requests only).

Later revisions of the eBook will be downloadable using the same link that will be emailed to you, so you don't lose anything by buying the first version (but bear in mind it is a draft version!).

You must use the latest v1.B0 Beta version of E2B and the latest MPI Tool Pack v0.039 (from here).

Any comments welcome, it is a complicated subject and I had a lot of difficulty trying to make it clear and logical (and probably failed!).

Fast E2B USB 3.0 drives - which is best? (GTX v. SSD v. M.2)

When booting from an E2B USB drive, the speed will depend on the speed of the USB drive and also on the BIOS USB driver.

I decided to test out three of the fastest Fixed disk-type USB 3 drives I have using my Asus Z87-A PC. Any of these three USB drives will comfortable run WindowsToGo or full Linux:

E2B and MPI Tool Pack has been updated

The latest version of E2B is now v1.B0p and  MPI Tool Pack is v0.093v14. There has been a small bugfix to SWITCH_E2B too.

I have spent many weeks writing an eBook on UEFI payloads for E2B (complete with Exercises) and I am just tidying it up. It should be ready in a few weeks. If anyone wants to obtain an early copy then give me your email address, but you must agree to provide feedback on at least 50% of the eBook and work though at least some of the Exercises and test the E2B drive on at least three different PCs/Notebooks! I will limit this to the first 20 requests only (just in case I get 100's of requests!). Email me at steve  (at)  easy2boot (dot) com or use the Contact Me page.

I have removed the trial WinPE downloads now. They are no longer available.

I have built a WinPE download file that includes WinPE32 and WinPE64 .wim files and also includes a SWPEFAT32  partition image file which also includes these two WinPEs.

Details of how to obtain this download and how to make the E2B drive, will all be in the eBook.

This means if you make a FAT32 2nd partition on your E2B drive (replace the existing one) containing the files in the download, it should UEFI-boot on any system to WinPE.

Also, you can choose which extension to use for your .imgPTN files:

Ubuntu.imgptn23    - the FAT32 partition is kept

 --- OR ---

Ubuntu.imgptnX4SWPEFAT32 - the SWPEFAT32 partition image file is inserted as Ptn4

If you wanted to keep your 2nd partition as NTFS, you would have to use the X4 file extension.

The download also includes MemTest86 which you can run if you include rEFInd in your .imgPTN files and you can also MBR-boot to WinPE32\64 if you really want to.

If you do add a second FAT32 partition containing these files, there are some disadvantages however (such as some systems will not allow you to MBR-boot from the E2B USB drive!). These issues + workarounds are discussed in the eBook too.

UEFI-booting is easier if you add rEFInd when you make your .imgPTN image files, but this will 'break' Secure Boot, so adding rEFInd is a choice you will need to make.

E2B v1.B0m Beta available

Changes in latest E2B v1.B0m Beta are:
1. Update Portuguese language file (thanks to Jeider)
2. Fix bug if running a .imgptnX4 file and X4 filename is longer than 14 characters.
3. Fix bug if '3GB', '4GB', '32' or '64' found in X4 filename it could prevent file from being listed in menu.

UEFI-multiboot for E2B now supports UEFI 32-bit and 64-bit

I have made a dual WinPE partition image for use with Easy2Boot X4 files.
This allows you to select and boot from a variety of UEFI payloads on an E2B USB drive without the need to Legacy\CSM-boot or find another Windows system to run SWITCH_E2B.exe.

Here is how to do it...

Latest versions update

Latest versions are here.

• Easy2Boot v1.B0l
• MPI Tool Kit 093v11
• SWITCHPE_russian_mini_v4
• SWITCH_E2B v1.1.20 

SWITCH_E2B and Easy2Boot will now first look for any second auxiliary image file in the \_ISO file on the second E2B partition. This gets around the problem of having to re-order the two files.


e.g. So both these arrangement of files will now work...

Ptn1: \_ISO\LINUX\Ubuntu64.imgptn  (this image is set as Ptn1 when switched in)
Ptn1: \_ISO\LINUX\Ubuntu64         (this image is set as Ptn3 when switched in - file must follow the first one on the disk or it will not UEFI-boot on some systems)

New:
Ptn1: \_ISO\LINUX\Ubuntu64.imgptn  (this image is set as Ptn1 when switched in)
Ptn2: \_ISO\Ubuntu64               (this image is set as Ptn3 when switched in)

In the second case, the second file will always follow the first one because it is on the second partition.

Latest news and updates for E2B + rEFInd

I have been testing various combinations of partition types on different systems and also had some feedback from users.

The latest version of E2B and SWITCH_E2B.exe has a few changes and bug fixes.

The X4 file can now also be placed on the 2nd partition of your E2B USB drive. This solves the problem of having to re-order the two files if they are not in the correct order for UEFI-booting.

e.g.
Ptn1: \_ISO\MAINMENU\Ubuntux64.imgptnX4SwitchPE   (FAT32 .imgPTN file with rEFInd)
Ptn2: \_ISO\SwitchPE                              (partition image containing WinPE)

The latest versions at the time of writing are:

Add Notfall 13 2019 ISO to E2B

Here is how to add the German Notfall 13 2019 ISO to E2B.

You can simply add the ISO to one of the E2B menu folders.

If you want to change the menu system configuration files or want a 'flat file' installation so it can store updates (?), etc. and UEFI-boot you may want to create a .imgPTN file for it.

These instructions stems from a thread on reboot.pro here.

Note that to test it under VirtualBox, you need to pick one of the Safe Mode (old PC) options or else it will crash!

Create 'flat file' .imgPTN image

MPI Tool Kit v0.093 Beta with rEFInd (UEFI-multibooting of different .imgptn files is now possible)

New Betas for UEFI-multiboot support without needing to MBR-boot!

E2B v1.B0i Beta and MPI Tool Pack v0.093v7 Beta will allow you to select any UEFI-bootable .imgPTN file without needing to CSM boot or needing to run SWITCH_E2B on a different Windows system.

Each .imgPTN file must include rEFInd so that when it UEFI-boots, the rEFInd manager is loaded.

You can then choose to boot to the UEFI payload (linux, KonBoot, Windows Installer, etc.) OR boot to WinPE and run SWITCH_E2B.exe where you can choose to load a different .imgPTN file.

The new MakePartImage only fully supports adding a 64-bit WinPE UEFI, but you can add both 32-bit and 64-bit WinPEs using the X4 method or the second partition method (see below). Since pure 32-bit UEFI systems are quite rare, I have not catered for them in MakePartImage.

Outline of new changes:

E2B v1.B0h available

This version v1.B0h has a few very small tweaks to the Make_E2B.exe GUI but I also have removed nircmd.exe from the SDI_CHOCO folder because this was causing some AV software problems when downloading or extracting E2B.

nircmd.exe is still used by SDI_CHOCO and it still speaks to you as the installation proceeds, because it extracts the file during the Specialize pass.

Add 'SuperinSecureUEFI-Boot' to your E2B USB drive

There are two projects on GitHub which are of interest to USB-booters.
This was mentioned on reboot.pro recently and also pointed out to me by Alex G.

The first project (by thias) is a multiboot menu system based on grub2 called 'glim'. It automatically detects .iso files and builds a menu each time it boots (does it sound familiar?). It supports UEFI and MBR booting.

The second project (by ValdikSS) includes 'glim' and is a UEFI+MBR multiboot project which allows you to UEFI Secure Boot, UEFI-boot or MBR-boot and then run secure or unsecure payloads from the grub2 menu system.

The downside is that for Secure Boot, you have to register the bespoke grub2 efi file using a certificate that is provided. This adds the certificate into the NVRAM of the system UEFI firmware and so it 'changes' the target system.

Set the timeout so it autoboots if you like!

Use the GRUB Live ISO Multiboot menu entry...

I only added one ISO...

Comparison between UEFIinSecureBoot and E2B grub2 menu system v10

• E2B grub2 allows Secure Boot without using MokManager and so does not change the target system.
• Both systems can Secure Boot (using MokManager for insecureBoot) and run both secure and insecure ISOs and other non-EFI payloads.
• UEFIinSecureBoot should Secure Boot and run non-secure EFI payloads ??? (not tested).
• UEFIinSecureBoot can Secure Boot and access files on an NTFS partition, when Secure booted however, E2B grub2 can only access a FAT partition.
• Both systems can be expanded by adding more menu files.
• UEFISecureBoot uses a graphical grub2 theme menu, this type of menu runs very slowly on some systems (E2B grub2 menu system does not use a theme for this reason).

If you want to try this you can download the ready-made .imgPTN23 file here.

Instructions

E2B v1.B0g Beta now available (Make_E2B.exe now automatically creates 2nd partition if large USB disk)

v1.B0g is now available.

If you make a new E2B USB drive and the USB drive is larger than 128GiB, then the cmd script will now use Windows Diskpart to create a second maximum-sized partition. Note that if you have a >128GiB USB Flash drive (removable-type) then Windows 10 Build 1703 or later is required, otherwise you will just get the usual small 31K 2nd partition.

The filesystem choice is left up to Diskpart to decide - if the second partition is less than 32GB, it will be formatted as FAT32, if larger then it will be formatted as NTFS.

You can still make a single large first partition if you wish, if you run the .cmd file instead of the clicking the big red button in Make_E2B.exe.

Changes from the current v1.A0 released version are:

E2B 1.B0f available

The latest version is v1.B0f Beta version which has a few small bug fixes.
Check the Version History for details.

At least two pupils in the same school class will have the same birthday - probably! (the 'Birthday Paradox')

Our old Maths teacher always used to do this trick with every new class intake each year...

First, he would ask the question 'What are the chances that at least two pupils in this class have the same Birthday'?

After asking for our guesses, he would ask anyone in the class to raise their hand if they had a Birthday in January. Then he would ask each of the pupils who had raised a hand to shout out the day they were born on, e.g.Tom shouts '21st', Victor shouts '12th', etc. and then he would go on to February, etc. until someone else shouted out 'YES' if they had the same Birthday.

Theoretically, with a class size of 30 pupils, there is a 70% chance that two or more pupils in the same class will share the same Birthday (and probably the same birth-year as well). Our Maths teacher would tell us that he would explain this when we came to study probabilities, but he also said something else which peaked our curiosity...

He said that he had been doing this test for many years now and with many classes, and that he has found that the probability was actually much better than the theoretical 70% figure!

He would then ask if anyone could think of why this should be?

E2B v1.B0b Beta available (install windows 7 on modern USB 3 systems)

Download latest E2B v1.B0 Beta

• Bugfix in countfiles.g4b for windows ISOs with .iso324GB suffixes not being counted properly (the Windows folder had to have at least one .iso or .imgPTN file to be shown in menu - now it will work even if only one .iso32 or .iso4GB etc. file is present).
• ALT_ISO variable support added and \_ISO\docs\Sample mnu files\Windows\Install Windows 7 with USB 3 (WinNTSetup).mnu for installing Win7 on modern systems.

• Some new file extension suffixes are now recognised:
     NCQ (non-contiguous+quiet)
     QUIETP (redir+redirp)
     QUIET   (redir)
• .isoboot file extension now supported - will boot a non-contiguous linux iso using isoboot only

E2B v1.A9 is now released!

v1.A9 2019-02-19 Includes a new file extension override feature, a new WinNTSetup feature and a new filename sort prefix feature.

E2B v1.A9k Beta available (with new sort override prefix feature)

This version also has a new 'sort prefix override' feature,

As you know, E2B will alphabetically sort the menu entries.

This means that Mint.iso will always be listed before Ubuntu.iso unless you rename the Mint.iso file to zMint.iso.

However, the E2B menu will then list the file as zMint.iso, so then you need to make a .txt file (zMint.txt) so that the menu entry looks nice.

The new feature in E2B 1.A9k allows you to avoid having to make a .txt file - you just rename the payload file using a sort prefix override.

The new sort prefix override

E2B v1.A9h and v1.A9i

Note: Version 1.A9i has now been added.

1.A9h has the following changes from v1.A8:

1. New feature: can use extension override xxxxxx_.(override).iso in filename - e.g. hirens_.isowinvh.iso - override must start with _. and works for any extension. The extra _.fileext.xxx text is removed from the menu entry if EXTOFF=1 is set.
2. New feature: xxxxx_.WinNTSetup.iso now causes any Windows install ISO (except XP) to run WinNTSetup automatically and supports dual x86+x64 ISOs - you can also use your own batch file to automate WinNTSetup by using the STARTUP variable in a .mnu file (blog here).
3. Improvement: Make_E2B.exe now has graphical buttons.
4. Improvement: E2B_Editor.exe revised to add 4 extra options for centering menu text, etc.
5. Improvement: minor changes to \_ISO\e2b\grub\menu.lst for small speed improvements.
6. Improvement: remove countiso.g4b to speed up enumeration of Windows ISOs.
7. Improvement: .imgPTN code in QRUN.g4b now checks for grub4dos backup sector at LBA1.
8. Improvement: QRUN.g4b now detects HAIKU ISOs and suggests using the .HAIKU file extension.
9. Improvement: Windows Install ISO 'Repair only' prompt now changed to 'Repair\Setup' because pressing ENTER will now boot using WIMBOOT and so the ISO will be loaded as a virtual DVD and Setup will run without using an XML file.
10. Improvement: Util_Man.exe hack now launches control panel automatically.
11. Extra: added netrunner+persistence sample mnu file.
12. Bugfix: in QRUN.g4b for redir not suppressing all output if NOSUG is set.
13. Bugfix: fix QEMU_MENU_TEST bug when 9 or more drives in system.
14. Bugfix: TimeAccess.g4b sometimes miscalculated.
15. Bugfix: QAUTO.g4b and AUTOMN.g4b now does not use reserved memory at (md)0x230.

v1.A9i

1. Improvement: extension override now works for '32', '64', '3GB' and '4GB' suffixes so the menu entry is not listed in the E2B menu - e.g. Win10x64_.isodef64.iso - the menu entry is only listed on 64-bit systems.
2. Improvement: use --mem --top instead of --mem where the payload may be very large, e.g. Win10.vhdmem.

Microsoft have now blocked the Windows UtilMan.exe password hack... but you can still use it - if you know how!

Since about September 2018, Microsoft's malware detection software will attempt to detect if the UtilMan.exe file has been changed and will delete the 'bad' UtilMan.exe file.

This should mean that replacing the UtilMan.exe file with the cmd.exe file as a means of gaining access to a Windows OS without knowing any user password should no longer be possible and the E2B UtilMan Hack will no longer work.

However, if you boot to Windows in Safe Mode, it delays the removal of a 'bad' UtilMan.exe file by approx. 30 seconds and this is long enough for us to use it to run a cmd batch file and create a new ADMIN user account.

I have updated the UtilMan hack instructions now and revised the .cmd files in E2B v1.A8f Beta to work around the new protection.

E2B v1.A9e Beta available

I have improved the WinNTSetup and WIMBOOT support in E2B.

Download v1.A9e here.

Changes are:

E2B v1.9Ad Beta available

The v1.9Ad Beta version supports the automatic launching of WinNTSetup from a Windows ISO.

You can now cause a Windows NT6-based install ISO (Vista to Server 2019) to boot and run WinNTSetup and automatically load the same Windows install ISO as the WinNTSetup source file.

E2B v1.A9b Beta has new extension override feature

By special request, you can now make an ISO run as if it had a different file extension under E2B by changing it's filename...

v1.A9c allows any extension to be used (not just ending in .iso) and does not display the ._xxxxx part in the menu either (so Ubuntu 64-bit_.imgptn23auto.imgptn appears in the menu as Ubuntu 64-bit).

ubuntu64_.isodef.iso will run without prompting the user.

Force a different file extension (E2B v1.A9+)

Filename format:                filename_.forceextension.iso

Note: _. is mandatory, forceextension can be any extension recognised by E2B.

Examples:       msdart6_.isoPE01.iso                    (runs as if .isoPE01)
                       Windows8_x64_.isodef.iso            (does not prompt user with suggestions)

For example, if you have an ISO file but you want it to run as if it had a .isofira01 file extension, you can add _.isofira01 as a file override to the end of the filename but before the file extension of .iso.

A file  'myxp.iso' can be run as if it had the .isofira01 file extension if you give it a name myxp_.isofira01.iso.

This means that the file will keep the .ISO extension which may be more convenient if you are using a Zalman\IODD device as your E2B drive or if you want to keep the file extension unchanged for other reasons such as loading it into ImDisk or an ISO editor or mounting it with Windows Explorer.

E2B grub2 menu system Beta10 is now available

You can download the new grub2 menu system files from the Alternate Download Areas or click here.

The web page http://www.easy2boot.com/uefi-grub2-ptn2/ has been updated with the new changes.

Secure Boot

Cheap SSDs for your E2B USB drive from Amazon

The TC Sunbow SSD 120GB $21 ($29 for 240GB) plus a $10 enclosure is a cost-effective alternative to a Corsair GTX 128GB $73 or Sandisk Extreme Pro $39.50.

You can buy an Inatek USB SATA disk enclosure for just $10.

And when you don't need it anymore or if you want to buy a bigger drive, you can use it to upgrade your old laptop.

We all need plenty of flash memory...

The rover's Mars mission was almost a failure on 21st January 2004 due to software, a DOS-based filesystem and not enough flash memory - here's what happened...

Boot Windows Install ISOs from the E2B grub2 menu system

If you want to, you can add all your Windows Install ISOs to the E2B grub2 menu system which uses wimboot to load the boot.wim from inside the ISO and then uses ImDisk to load the ISO as a virtual DVD under WinPE. You do not need to modify the Microsoft Windows Install ISO in any way.

BUT you can only MBR-boot from them, UEFI-booting from ISO files is not supported.

I have added instructions at the bottom of Tutorial 145 on the RMPrepUSB site for the E2B grub2 menu system.

E2B v1.A9a Beta available

v1.A9a Beta

• New version of Make_E2B.exe with graphical buttons (because many non-English speaking users seem to ignore the big red button and click on the small Make_E2B_USB_Drive.cmd button and then they don't understand all the English questions!). 
• Changes to \_ISO\e2b\grub\menu.lst for small speed improvements.
• Improve speed on Windows ISo counting and remove countiso.g4b batch file.
• Bugfix in .imgPTN code in QRUN.g4b now checks for grub4dos backup sector at LBA1 to prevent unnecessary LBA30 error message. 
• Add netrunner+persistence sample mnu file.
• Bugfix QRUN.g4b - redir not suppressing all output if NOSUG set.
• Bugfix in TimeAccess.g4b - sometimes miscalculated.
• Bugfix in QAUTO.g4b and AUTOMN.g4b (used reserved memory at (md)0x230).

How to switch back to the E2B partition from a linux OS when using .imgPTN files and UEFI-booting

When you UEFI-boot from a FAT32 .imgPTN file (after you have 'switched' it in), then there is no front-end boot manager. Whatever payload you have used is directly booted to. In this way E2B can secure-UEFI-boot to many different types of payloads without any issues or complications caused by other bootloaders/bootmanagers getting in the way.

The problem is that if you only have access to systems which will ONLY UEFI-boot, then it is difficult to change the payload to something else!
