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.

E2B v1.B0a Beta now available

This version (E2B v1.B0a Beta) has a few new features:

• 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!

Fix issues with VirtualBox v6 and VMUB (fix --startvm error)

The new version 6 of Oracle VirtualBox has changed executables and so it has (deliberately!) broken backwards compatibility with all earlier scripts, shortcuts and applications which call VirtualBox.

This includes DavidB's VMUB application. To make VMUB work with the new VBox 6 version:

Add NetRunner ISO with persistence to E2B

You can add persistence to a NetRunner Live ISO using a .mnu file.

Here is one for 19.01. Just follow the instructions in the .mnu file. I used a 500MB persistence file.

The kernel parameters were discovered by looking at the live.cfg file from inside the ISO.

The name of the persistence file does not have to be netrun-rw. You can have multiple .mnu files and multiple persistence files if you wish.

If you want to move the persistence file to the same folder as the .ISO file, then specify $HOME$/netrun-rw for the PF variable value.

Prevent Windows 10 from blocking 'infected' downloads

If you have the default Windows 8\10 antivirus features  active, you may find that sometimes Windows will prevent you from downloading a file that it 'thinks' is infected with malware but that you know is clean.

If you have installed a 3rd-party AV solution, you are often given the choice to keep and use the file anyway, but not with the standard Windows 10 download manager.

The registry fragment below allows you to download the file and keep it (but you may still get a warning from Windows Defender if it thinks it contains malware).

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Attachments]
"ScanWithAntiVirus"=dword:00000002

Save these 3 lines to a file called DontBlockDownloadedFiles.reg and double-click on it to change your Registry setting.

Then reboot (or log off and on again) to make the setting active.

The default value is normally 3. A value of 1 prevents any warning from being given.

1 = always allow downloads

2 = warn if positive

3 = block if positive

Tip: After downloading the file, check it using virustotal.com (if you install the app, you can right-click on the file to check it).

E2B v1.A8 is now released!

The new v1.A8.exe download is released and can be downloaded here.

It can also be used to update the DPMS version of E2B.

The E2B website will be updated with this new version in a day or so.

Note: If you updated to RC1 previously, you may find two copies of Memtest86 (MBR+UEFI) in the \_ISO\UTILITIES_MEMTEST folder, delete the Memtest86 (MBR+UEFI).imgPTN file and keep the Passmark Memtest86 (MBR+UEFI).imgPTN file.

I have also updated the two E2B eBooks. You can use the link in your confirmation email to download the new version(s) if you wish. The changes are very minor and just add that you may no longer need a WinHelper flash drive if your E2B drive is of the fixed-disk type.

List of changes since v1.A7:

E2B v1.A8 Release Candidate 1 now available

v1.A8_RC1 is now available for testing.

E2B v1.A8 RC1

Press ENTER to Skip WIMBOOT if it causes a problem (e.g. <1GB RAM)

List of changes since v1.A7:

Has anyone ever seen this error when using E2B?

One user gets this error after selecting any .imgPTN file...

I have never seen it so I would like to know if anyone else is having problems with .imgPTN files before I release the new version of E2B.

You can email me at steve (at) easy2boot (dot) com.

E2B v1.A8j Beta available

v1.A8j Beta has a few more tweaks and a new default background.

Ctrl+F8 hotkey now reloads E2B (useful if the menu stops working properly due to a bad payload failing to boot).

Almost ready for release...

E2B eBook New Year sale ends Sunday 13th January 2019

The 'Getting started with E2B' eBook is currently available at a reduced price of only $5.

If you also purchase the 'How install Windows' eBook, you can get them both for $11.69 (inc. discount).

Click here for details.

I intend to update both eBooks soon to incorporate the new changes in E2B v1.A8. If you purchase them now, you can get up to 4 revised versions as they become available, by using the email link that will be sent to you at the time of purchase.

E2B v1.A8h Beta now available

v1.A8h - A few more tweaks. Ready for release soon, I think!

I am keen to fully release it because it means USB Hard Disks can now directly boot Windows Install ISOs without needing a WinHelper USB Removable flash drive - also testing them in a VM is now easy!

E2B v1.A8f/g Beta available

This Beta v1.A8f  has extra code so that typical All-In-One ISOs such as the Murphy Install ISOs will hopefully 'just work' when placed in either a standard menu folder or one of the \_ISO\WINDOWS\xxxxx folders. This means you can run a 'Murphy's 24-in-One Windows Install ISO' and his scripts will run correctly.

Note: v1.A8g has a couple of bug fixes: (1) XP install using WinPE now can use WIMBOOT, (2) repair option when user hits ENTER when selecting Windows 8/10 install ISO now works, (3) .iso01 file extension fixed.

I have been experimenting with the startup files in WinPE but found there is a lot of bad, inaccurate and misleading information about the WinPE startup process on the web! I could not find a complete and accurate description or flowchart anywhere, even the Microsoft documentation was inaccurate (no surprise there then)!

I think I have now worked out how WinPE actually starts up and how the various files are used.

I have done quite a bit of testing using Windows Install ISOs...

The 'correct' WinPE startup process is actually this...

E2B v1.A8e available

This version v1.A8e has a few more tweaks including a fix for Setup giving a 'We couldn't create a new partition or locate an existing one" error which prevents installing from a Windows ISO when booted from a standard folder.

E2B v1.A8d updated

Version v1.A8d was updated on 2019-01-05 for language strings + other tweaks. Please download it again and update your E2B drive.

Version v1.A8e has a few more tweaks including a fix for Setup with WIMBOOT giving a 'We couldn't create a new partition or locate an existing one" error which prevents installing from a Windows ISO when booted from a standard folder. It turns out this error message which you see when selecting a drive to install to at the beginning of Setup, is due to Windows Setup identifying the Removable USB flash drive as the 'boot' disk or 'system' disk - Windows needs to install the boot files to the 'boot disk' of the PC but it refuses if it thinks that a Removable drive is the boot disk. The usual fix is to remove all other Removable media, including SD cards and other USB drives, then switch off (not restart) and on again.This is also the reason why sometimes you can install Windows using a USB hard disk, but when you reboot, you find that the boot files have been installed onto the USB hard disk instead of the internal 'first' hard disk - and the system will only boot to Windows if you boot from the USB hard disk!

One main difference is that if set NOHELPER=1 in your \_ISO\MyE2B.cfg file, then WIMBOOT will not be used if there is not sufficient RAM in the system (Vista requires 800MB, Win8/10 requires approx 1.3GB).

NOHELPER is a variable which means that your USB drive is of the Removable type (hence E2B does not need to look for a WinHelper flash drive). It is usually set by the Make_E2B .exe or .cmd file when you make the E2B USB drive.

WIMBOOT will still be used if you place your Windows Install ISO in a normal E2B menu folder however.

E2B v1.A8c/d Betas now available

This version v1.A8c  now has support for the .isoPELD and isoPELD1 file extension.

Also version v1.A8d now includes support for dual-architecture 32\64-bit Windows Install ISOs with WIMBOOT. Note: v1.A8d was updated on 2019-01-05 for language strings + other tweaks.

Using the .isoPELD file extension causes an ISO containing a \sources\boot.wim file to boot as usual, but then uses WIMBOOT and ImDisk to load the ISO as a Virtual CD\DVD (usually as drive Y:) so that the files inside the ISO are automatically available to WinPE. .isoPELD runs image #2 in boot.wim while .isoPELD1 runs image #1 in boot.wim. I have not actually found a use for these yet however!

This new Beta version also fixes some typos in all the Sample Disk1 XML files for use with VMs. It seems that Setup is case-sensitive and I had accidentally used...

<Diskid>1</DiskID>

instead of

<DiskID>1</DiskID>

which causes Setup to complain about a bad XML file at line xx in C:\AutoUnattend.xml!

By using VirtualBox+VMUB and the Disk1 XML files, you can now test out an automated install (including an SDI_CHOCO install). Note that you need to allocate 1.5GB or more of RAM to the VM.

See also the previous blog for other changes.

Brief instructions for testing an SDI_CHOCO installation under VBox

E2B v1.A8b/c Beta now available

This version v1.A8c should now automatically boot Windows Install ISOs (Vista to Server 2019, but not dual 32\64-bit ISOs) from any of the E2B menu folders.

The E2B USB drive does not need to be of the Removable type.

For example, just copy your Windows 7, 8 or Windows 10 install ISO to the \_ISO\MAINMENU folder.

\_ISO\MAINMENU\Windows 10 1809 64-bit UK NCQ.iso

The ISO does not need to be (very) contiguous, so you can prevent E2B from complaining if it is not contiguous and prevent it from showing the usual E2B messages and prompts by ensuring the name ends in 'NCQ.iso'.  You can instead use .isodef as a file extension to suppress E2B suggestions but E2B will expect the file to be contiguous and may complain if it is not!

The file name can contain spaces if you wish or you can make a matching .txt file for it in the usual way.

Note that for Win8, 8.1 and early Win 10 ISOs, you will need to input a generic installation Product Key when prompted by Windows Setup. You cannot specify an XML file (you must place the ISO file in one of the \_ISO\WINDOWS\xxxx folders if you want to use an XML file and suppress the Product Key prompt).

Let me know if you find any issues...

E2B v1.A8a Beta available

Booting Windows install ISOs no longer requires an extra WinHelper USB flash drive!

If your E2B USB drive was a 'fixed disk' then previous versions of E2B required you to also connect a WinHelper USB Flash drive to the system because on all versions of Windows NT6 (Vista to Win10 1609) the \AutoUnattend.xml file had to be on a 'Removable' USB drive in order for Windows Setup to detect and use the XML file.

The alternative was to convert the ISO to a .imgPTN file.

This new version of E2B uses 'wimboot' which is part of the open source iPXE project here.

Add Manjaro Live UEFI-64 to E2B

If you convert a Manjaro ISO using MPI_FAT32 (MakePartImage) the resulting .imgPTN will not MBR or UEFI boot.

The grub2 EFI boot file included with Manjaro, only seems to support the CD iso9660 file system and does not understand FAT32 filesystems.

If you use Rufus, you must use the 'dd' raw copy option and not the UEFI FAT32 or GPT options.

To fix this, find a Ubuntu or Mint x64 Live CD ISO file, and...

1. Switch the Manjaro.imgPTN file on the E2B USB drive so that the \EFI\BOOT folder is visible in Explorer.

2. Use 7Zip or some other program to extract the two EFI\BOOT\*.EFI files from the Ubuntu ISO.

3. Copy the two files into the \EFI\BOOT folder on the E2B drive.

4. For CSM Legacy booting, add these 4 lines to the end of the \menu.lst file (see \boot\grub\tz and the \boot\grub\locales\keyboards file for your country codes - e.g. en_US New_York us).

Merry Christmas!

To those who celebrate Xmas, have a good day

E2B eBook - special Xmas offer!

Christmas day and it's 3 p.m. - so you've opened all your presents, uncle Fred is snoring his head off (and you are vaguely wondering how he had any room for Turkey after having consumed so much sherry, wine and port), auntie Doris is making the room virtually uninhabitable due to eating too many Brussels sprouts and Dad is tactfully blaming the dog for the awful smells!

Everyone else is watching 'Suits' on Netflix (though Meghan Markle maybe worth watching again for the tenth time this year).

You will have to wait hours for the batteries of your new Xmas present, a 'Gatwick special' drone, to charge up before you can try it out over nearby Heathrow airport... and you are feeling very bored.

Well now is a perfect time to get to know how to use E2B properly. Why not add some DOS games, add a bootable version of KODI (OpenElec) or play 100's of retro games using your old USB games controllers (LAKKA) or boot to a full Windows 10 installation (WinToGo).

So, just for this Christmas period only, I have reduced the price of the E2B eBook How to make a multiboot USB drive using Easy2Boot to just $5 (but you can give more if you want to ;-) ).

Merry Christmas!

E2B v1.A7 now released

This new version is available from the Alternate Download Areas now (download link for OneDrive here).

It will be uploaded to the E2B website in a day or two.

E2B v1.A7 (changes from v1.A6):

E2B v1.A7h Beta with Server 2019 support added

E2B v1.A7h Beta now has an extra folder added for Windows Server 2019 ISOs and .imgPTN files.

The Beta is available from the Alternate Download Areas as usual.

Please let me know if you find any issues. I hope to release v1.A7 before Christmas.

So if anything requires tweaking, now is the time to tell me!

Add COMSS Russian/English AV+Utilities Boot Disk to E2B

The COMSS boot disk comss_boot_usb_2018_07.iso  does not seem to be bootable as a .ISO file, so I converted it to a FAT32 .imgPTN file and used Syslinux v6.03 (603) when prompted by MakePartImage.

Once the .imgPTN was switched to, in order to get F-Secure to boot, I also needed to rename the
\boot\iso\rescue-cd-3.16-73600\boot\isolinux folder  to...
\boot\iso\rescue-cd-3.16-73600\boot\syslinux.

Once that was done, most of the menu items seemed to work as expected.

Endless OS - an easy-to-use Linux-based OS for schools, businesses and everyone!

I just came across Endless OS. It seems to be very easy to use and install apps onto - you would hardly know it was Linux-based!

I downloaded the Basic ISO (eos-eos3.5-amd64-amd64.181116-185419.base.iso 1.8GB) and it boots fine on E2B as a LiveCD.

Booting from a .ISO file + persistence does not seem to be available, so when booting from the ISO as a LiveCD you will not be able to install any large apps, etc. so you may want the 'full' version, however even the Basic version seems quite useful.

MPI Tool Kit v0.088 available

v0.088 2018-12-05

• Add syslinux v6.03 option
• Default to syslinux v4 instead of v3
• Now uses 7z.exe instead of the 7zg GUI for unpacking (doesn't stop if 'extra data found' warning and seems to be faster)
• Menu.lst updated and some small bugs fixed plus options to disable some menu entries
• User can now add their own menu.lst file if using a GFX menu file
• Forcibly auto-dismounts the .imgPTN file after a small delay
• Sample MyCSM files updated
• Bugfix in menu.lst for text mode MyCSM.cfg menu heading/footer to be displayed
• Try to fix timing issue as occasionally can get 'access denied' errors when running LREPLACE.cmd and ssed.exe.

This new versions has had quite a few changes but should be faster and more reliable.

Please let me know if you find any issues.

Is your laptop running slow ever since you bought a replacement AC power adapter for it?

Did you know that some AC power adapter connectors for laptops have a 'smart' pin?
If this pin does not carry the correct voltage or signal, your notebook will run very slowly.

About E2B v1.A7g and using the 2nd partition on the E2B drive for payload files

If you have a large (>128GiB) USB hard disk, I recommend that you use the first partition (up to 128GiB in size) for E2B and use the second partition for other purposes such as for storing utilities, hard disk backups, documents, etc. Note that only  recent versions of Windows 10 (1703+) can access the 2nd partition if it is on a Removable (flash) drive.

However, you can place most payloads such as linux .ISO files, Windows VHD files, etc. on the second partition and add the PTN2_MNU.mnu menu file to one of the menu folders (e.g. add it to \_ISO\MAINMENU). The PTN2_MNU.mnu will take you to a sub-menu where all the files in the folder on the second partition will be listed and you can then boot to any one of them.

Note: Windows VHD files will only boot from partition 2 on a Removable USB drive if the VHD contains Windows 10 1703 or later. However, there should be no restriction if the USB is a hard disk.

The 128GiB USB BIOS bug
Note that due to some BIOSes (e.g. Asus EeePC's) having a bug in their USB driver, they are not able to access files past 128GiB on the USB drive. This bug is quite common, especially on older USB 2.0 only systems. This means that grub4dos will not be able to access the file if it has a sector address higher than 128GiB on the disk. This is why I suggest you do not use a USB drive larger than 128GiB - or at least keep the E2B partition below 128GiB in size.

If the file is beyond 128GiB on the drive (e.g. in a 2nd partition on a >128GiB USB drive) then grub4dos may be unable to access it.

E2B will warn you if the BIOS has this 128GiB bug as soon as it starts to load.

Sometimes, you can fix the BIOS bug by loading the grub4dos USB 2.0 driver which replaces the buggy BIOS driver (hold down the SHIFT key just as E2B starts to boot to load the grub4dos USB driver). However, the grub4dos USB 2.0 driver only works on older USB 2.0 systems and not with newer chipsets or USB 3.0.

Tip: If your system has this BIOS bug but does not have any USB 2.0 ports and you have a USB 3.0 E2B drive, then connect the E2B drive to a USB 3.0 port using a USB 2.0 cable - this may allow the grub4dos USB 2.0 driver to work because it will use the USB 2.0 connections instead of the USB 3.0 set of contacts.

Windows ISOs
You may have noticed that I said that you can place most payloads on the second partition - well  Windows Install ISOs were an exception, but not now!

I have tweaked E2B v1.A7g so that you can, if you wish, add Windows Install ISOs onto the second partition (all types of Windows ISOs - except XP ISOs).

Here is how the 'cheat' works...

E2B v1.A7f Beta available (and a bug found in robocopy!)

E2B v1.A7f Beta is here. The change is just in the new Backup .cmd script.

I failed to notice that the Backup_E2B_drive_to_MASTER.cmd backup script actually made a hidden folder on the Desktop instead of a normal, visible folder!

This was because I have 'view Hidden files' ticked in my Explorer options and so I didn't spot that the Desktop E2B_MASTER folder was actually changed to be a hidden folder by robocopy!

It turns out that there is a long-standing bug in robocopy!

Build your own Windows 10 ISOs and include the latest updates

If you want to build your own Win10 ISO with the latest MS updates rolled-in, check out this article from ghacks.net.

The uupdownloader_1.0.0.exe can be downloaded from here.

Make sure that you disable your AV and that you have plenty of disk space, a fast internet connection and a lot of patience though! It also helps if you whittle down the number of Editions that you want to modify (e.g. just choose Professional if that is all you are likely to use, to save build time).

I managed to build an ISO successfully (it took over an hour!) but I haven't tested it yet.

When I ran it again to make the same ISO again however, it seemed to want to download the UUP files all over again...

Adding 32-bit UEFI boot options to Strelec WinPE

The English build of Sergei Strelec WinPE only contains entries to boot to Win10 64-bit in the UEFI BCD - no 32-bit UEFI boot options are present for Win10 or Win8. However the 32-bit EFI boot file \EFI\boot\bootia32.efi is already present, so to support booting from 32-bit UEFI systems we just need to edit the BCD...

E2B v1.A7e available

This version v1.A7e just has two Robocopy .cmd scripts added which you can use to quickly backup the files of your E2B partition to a folder (E2B_MASTER) on your Desktop and then you can restore it to the same USB E2B drive or a different E2B drive using the Restore script.

Files which are already present are not re-copied so only the changes are updated.

The contents of the target USB drive will be a duplicate of what is in the backup folder. This means that if you have extra files on your USB drive which are not in the backup folder, then the extra files will be deleted from your USB drive - i.e. it will be an exact duplicate.

Adding DBAN with UEFI 64-bit support to E2B

The standard Legacy-boot DBAN ISO is currently version 2.3.0 and can be simply added to your E2B drive. Version 2.3.0 should not erase USB drives (unless you select them!) even if you select an 'autonuke' option from the boot menu.

The current version does not support UEFI booting but if you have a 64-bit UEFI system which does not support MBR\Legacy\CSM booting, you can  use the Beta UEFI DBAN ISO here. It does not support 32-bit UEFI systems though.

Note: On some systems (e.g. Lenovo IdeaPad 300) DBAN v2.3.0 does not boot and gives a
"cat: can't open '/proc/cmdline': No such file or directory"
error. This new version however does seem to boot OK.

UEFI Beta 2017 version

Tip: Once DBAN starts to boot, remove the E2B USB drive in case of accidental erasure!

E2B v1.A7d Beta now available

E2B v1.A7d now supports the .isoDPMS file extension. If you have an XP WinPE-based ISO such as DaRT5 or ERD2005, it probably will not be able to see SATA hard disks once it has booted because it lacks the correct SATA drivers. By booting it using the DPMS feature, the correct SATA\RAID\SCSI 32-bit XP driver should be automatically added. This saves having to create a new .mnu file based on the ERD5_DPMS.mnu found in the Sample mnu files folder.

List of changes since v1.A6:

• .help files now don't display the first three UTF-8 bytes in a UTF-8 file
• Support for multiple .help files with different background images using a .mnu file
• Small bug fix to Update_E2B_Drive.cmd when an empty USB drive is selected
• Small fix to Add_Bootmgr_to_E2B_drives.cmd if empty floppy drive in system
• Small changes to Make_Ext.exe, Make_MyE2B.cfg.cmd, isoboot.g4b, QAUTO.g4b, QRUN.g4b (now does not warn if .help file is not contiguous)
• Fix bug in SDI_CHOCO - the %BIT% variable is now available in MyStartup.cmd and MySetupComplete.cmd
• Update WinContig.exe to latest version
• Minor bug fixes to some .cmd scripts in case your Windows TEMP path variable has spaces or other funny characters in it.
• .isoDPMS file extension supported for DaRT5\ERD ISO (will load 32-bit XP SATA\RAID\SCSI driver). You must have the DPMS version of E2B for this extension to work.

Download here or from the Alternate Download Areas as usual.

P.S. The Halloween 'surprise' code has been removed from this version.

Fix for occasional 'freezing' in Chrome browser when editing web pages (Windows 10 64-bit)

I use the WebNode online page editor to the edit pages of the Easy2Boot site.

For a long time now I have experienced a problem of 'freezing' for between 5 - 200 seconds after the first few edits which is very annoying. If I wait long enough, the cursor 'comes back' and I can continue using the mouse and keyboard - during the 'freeze' period I can use other Windows tasks such as other browser panes or other apps, I just cannot continue editing in the browser page I was using. If I save the page and then re-open it for editing, the freezing seems to stop for a few minutes before it starts again.

I noticed that the CPU fan was spinning faster when this freezing occurred and so I used Task Manager to find out what was using the CPU. I noticed that when the freezing occurred, the CTFLoader task was using over 50% of CPU resources, but when the freezing stopped, CTFLoader went down to about 2%. I also found that by using right-click - End Task in Task Manager on CTFLoader, the freezing could be stopped and I could resume typing in that browser tab.

So CTFLoader seemed to be causing the issue. SFC /scannow showed no problems however.

Then I read a post on reddit here which described how to solve it by stopping the 'Touch Keyboard and Handwriting Panel Service'. Since my PC did not have a touch panel and I do not use handwriting input services on the PC, I disabled and stopped the Service.

Win+R > services.msc >  'Touch Keyboard and Handwriting Panel Service' service > right click > properties > click STOP and change Startup type to Disabled. Then click OK. A reboot is only necessary if you find keyboard input no longer works in some apps (e.g. Edge).

Now all is good. I still get occasional freezing, but it only lasts a few seconds now instead of minutes!

P.S. I am not sure if this is relevant, but I do have Office 2007 installed on my PC but the freezing occurs before I use any Office 2007 applications.

[UPDATE] Well the 'freezing' has not completely disappeared whilst using the webnode web editor, however I have found a simple fix - when it freezes,  I just need to select a different Chrome Browser tab and then re-select the webnode browser tab.

XMLtoE2B v2.0.47 released

You can download XMLtoE2B v2.0.47 (updated) from here.

This includes a blank .diskcfg file - load this file to allow the user to select the install disk\partition instead of automatically wiping a disk.

I think this is near to release, so please let me know if you have any feedback or suggestions.

New XMLtoE2B v2 Beta

XMLtoE2B.exe is a Windows 32-bit utility that can modify an XML file for use with E2B Windows Setup.

Unfortunately, I accidentally deleted the source files of the current v1.0.39 version so it has not been possible to maintain it.

However, I have been spending many days working on XLMtoE2B version 2.

XMLtoE2B v2

The new version has a few extra options such as:
