'Ventoy for Easy2Boot' v1.0.79c released (bugfix)

Another problem was found with 'Ventoy for Easy2Boot 1.0.79' - Windows zip file injection was not working.

The issue has now been fixed in 1.0.79c.

Problem seems to be to do with the FAT code needing to specify ".xz " as file extension rather than ".xz" for FAT32 filesystems (three character extensions worked but not two character extensions) and also a bug in LongPanda's code created a file on X: even if the source file did not exist.

The new version is 1.0.79c (press F7 in Ventoy Menu to show version number).

Please run \e2b\Update agFM\Update_to_latest_Ventoy_version.cmd on Ptn2 to update to the latest version.

Check that the \ventoy\vtoyjump32.exe and vtoyjump64.exe has a date of 2022-09-09.

I have given details of the code changes here.

Major bank security loophole exposed - don't be a victim - use this simple fix!

Did you know that there is a major security flaw with most banks?

Did you know that if someone steals your bank card and your phone then they can easily clean out ALL your bank accounts in just a few minutes!

That's right - if a thief has stolen both your bank debit card and your phone - he/she can find out your bank card PIN number very quickly and can then use your bank card + PIN to steal all your money. They can even transfer all your money from your bank's savings accounts into your bank's current account too so that they clean you out completely!

Here is how it works...

E2B v2.16f Beta

I have added the Ctrl+F7 and Alt+F7 hotkeys to the new Beta version of the E2B menu system.
Some people have been experiencing blank screens when booting to the E2B menu system in legacy mode on systems with certain display adapters+monitors. So pressing Alt+F7 or Ctrl+F7 will instantly switch to a different graphic mode and screen resolution which may allow them to see the menu in the new mode.

Current changes in 2.16f are:
  • Add .wimboot file extension support. Use xxxxx_.wimboot.wim to make E2B boot using iPXE wimboot method instead of NTBOOT and bootmgr\BCD.
  • Add Ctrl+F7 hotkey to switch display to text mode. Use Ctrl+F8 to reload menu in default mode.
  • Add Alt+F7 hotkey to switch display to 1024×768 mode. Use Ctrl+F8 to reload menu in default mode.
  • New SWITCH_E2B.exe to fix not switching if partition 4 has start/size parameters but is Type 0
  • New \_ISO\WINDOWS\SVR2022 folder added for Server 2022 with XML and KEY files.
  • F1 ENGlish help text file updated.
Please Contact Me if you have any issues or suggestions.

'Ventoy for Easy2Boot' v1.0.79 bugfix for Windows Install ISOs and WinPE ISOs

I found a problem with 'Ventoy for Easy2Boot' v1.0.79 - it does not load a Windows/WINPE ISO as a virtual drive as it seems LongPanda has added an additional check into the code. This means Windows Installs and some WinPEs did not work correctly.

Please update 'Ventoy for Easy2Boot' using the instructions here.

The new version is still called v1.0.79 - so please update even if the cmd file says that you already have v1.0.79 installed.

The \ventoy\vtoyjump64.exe file on Partition 2 should be dated 2022-08-28 after updating to v1.0.79b.

Is YouTube getting worse or is it just broken?

I have some YT videos on my YT channel  and I have made comments on some other peoples YT videos, as I am sure many of you have.

For several years, I have noticed that sometimes, I can look through the comments under other peoples YT videos and I will be surprised to see a comment with my name on it but that I did not write. Here is an example:

Microsoft just made Secure Boot multibooting more difficult!

After the recent Windows update KB5012170 (August 9, 2022) was released, it seems Ventoy can no longer boot on some systems when Secure boot is enabled. This Windows update may also affect the Kaspersky EFI boot file used by agFM in E2B too.

Summary

This security update makes improvements to Secure Boot DBX for the supported Windows versions listed in the "Applies to" section. Key changes include the following:

Windows devices that has Unified Extensible Firmware Interface (UEFI) based firmware can run with Secure Boot enabled. The Secure Boot Forbidden Signature Database (DBX) prevents UEFI modules from loading. This update adds modules to the DBX.

A security feature bypass vulnerability exists in secure boot. An attacker who successfully exploited the vulnerability might bypass secure boot and load untrusted software.

This security update addresses the vulnerability by adding the signatures of the known vulnerable UEFI modules to the DBX.

KB5012170


Introduction

Ventoy (and the 'official Ventoy' .img files used by agFM) use an .EFI file which allows you to add any file or key onto the BIOS DB 'whitelist' by using MokManager. This basically allow you to secure boot to ANY unsigned .efi file and is therefore a very obvious security risk.

agFM uses a signed Kaspersky EFI boot file which has a security flaw because it allows you to load unsigned grub2 modules. The unsigned grub2 module can then disable the secure boot checks and then allow you to load unsigned .efi bot files.

Microsoft have released various Windows Updates which (if you have UEFI-booted to Windows) will add blacklist entries into the DBx non-volatile RAM of your BIOS so that it will now refuse to Secure Boot from the naughty EFIs that Microsoft should never have signed in the first place!

So this leaves us with a problem (that has been seen coming for several years) - how do we load a multiboot loader/manager such as Ventoy or agFM (which use unsigned grub2). Microsoft will not sign any generic grub2 version because they allow you to load other modules or run dd, etc. and thus potentially hack the secure boot mechanism.

E2B v2.16b Beta available

I have added support for the CTRL+F7 hotkey into the E2B menu system.

This hotkey sets the menu system to graphicsmode 3 and text mode.

If you have display issues on some systems and the E2B graphics mode menu system cannot be displayed properly on a particular graphics adaptor or monitor, you may see a 'fuzzy' or 'garbled' or 'corrupt' screen. In this case, hitting Ctrl+F7 may fix the display issue.

Please let me know if this causes you any issues and if you think it is worth keeping this feature in for the next full release.
