Error: AdjustCiOptions failed: 0xC0000002

[Jack3De]

I'm using version 1.3. I am getting an error:
Disable DSE...
CI!g_CiOptions at 0xFFFFF8011D829418.
Failure: NtSetSystemEnvironmentValueEx error 0xC0000002
The EfiGuard DXE driver is either not loaded in SETVARIABLE_HOOK mode, or it is malfunctioning.
AdjustCiOptions failed: 0xC0000002

I renamed the file on the flash drive, deleted the config, the flash drive was formatted in FAT, the file launch from the flash drive into the BIOS and Windows is successful.

Hi, there's really no need to email me to tell me to take a look at your issue less than an hour after creating it, GitHub already does this for you.

Code 0xC0000002 is STATUS_NOT_IMPLEMENTED. The HAL returns this when there are no EFI runtime services available for whatever reason. What this reason is, I can't say, but most likely this is somehow being caused by your system firmware (Dell BIOS).

Questions:

• Can you give the output of bcdedit /enum all? (attach as a text file since the output will probably be very long).
• Same question for bcfg boot dump -v (UEFI shell) or efibootmgr -v (Linux). One is enough, these show the same information.
• Can you try EfiGuard on another system (preferably not Dell), and if so, does this work?
• Is Secure Boot enabled in the BIOS?

Note that I doubt that I can fix this (assuming I'm right about the cause being the system firmware), but I may be able to identify what the cause is more precisely. As of right now I don't really have any ideas about what this could be.

1. bcdedit.txt

2. Of the three different computers, on one I managed to do this. Lenovo ThinkBook. On another laptop, HP, I got a different error, 0x000000E

3. Secure Boot disabled

[Jack3De]

Any ideas how to resolve this issue?

[Mattiwatti]

Nope, sorry. This does seem to be some hardware (or rather, firmware) specific issue, so there's not much I can do since I haven't got this specific laptop model to reproduce this.

I'll leave the issue open in case anyone has suggestions.

@horsicq: you are getting the same error, but for a different reason: your Windows is installed in BIOS mode (so on an MBR disk). EfiGuard will not work on this system as is but it will (well, should) work if you reinstall or convert Windows in UEFI mode (so on a GPT disk).

For converting your existing installation, see MS MBR2GPT: https://learn.microsoft.com/en-us/windows/deployment/mbr-to-gpt.

Ку, разобрался с проблемой? Если что я планирую переписать данный обход для EAC, он на данный момент работает только на Battleye, мой дискорд - css.os.4124.

@Jack3De Могу подсказать другой обход, не использующий EFI , но там бывают BSOD))

@cheboxarov This is a different error status than the one in the OP. The error message already tells you what the issue is.

@3d8kAbdul Please limit your posts to English only, so that others who don't speak Russian (including myself...) can also read them.
