    Apparently I found a missing import in ntoskrnl.exe in watchdog.sys from Build 7963, so I'll use the ntoskrnl_emu to fix that.
    I'll make new thread with the files and stuff.

    Hi for people who wanna know which version of win 8 beta boots on a uefi class 3 physical machine is windows 8 consumer preview I tried every single beta build and came out that consumer preview can be installed without any issues just like normal . I tested it in a physical laptop release on 2022 .

    My last idea is that using windows 8 consumer preview boot files on windows 8 dev preview. Why dev preview ? Because it looks like windows 7 once you disable all beta features. Also the dev preview is the version before win 8 consumer preview so I think we can use win 8 consumer boot files to boot win 8 dev preveiw

    AFAIK Windows 8 Developer Preview already support uefi class 3, so, no need to replace boot files

    Flashboot Pro DOES NOT WORK! Hang on "Windows is loading files", you literally cannot even load into the PE.

    Still no one that has bothered to test what I suggested?

    (I don't have any UEFI only machine)

    You Can Simulate The Situation By :
    1 - Disabling CSM
    2 - Enabling Secure Boot
    (Note 1: You Must Use Windows 7 With Integrated update KB5017361 To Enable Secure Boot)
    (Note 2 : Yes, I know that Update Supports Secure Boot For UEFI Class 1 & Class 2 Machines)
    So If You Disabled CSM Completely And Enabled Secure Boot, You Have Simulated UEFI Only PC.

    They Released Update v3.3P , Don't Forget To Disable Windows Security Before Launching App
    (Note : The App Is Completely Safe, But The Newer Exe May Needs A Newer Digital Signature)

    Thanks but the point is that is not my problem, I'll likely avoid any class 3 machine until the end of time.

    Perhaps I have an uncommon situation with my UEFI capable machine booting via Clover, the other are BIOS only, so it's a scenario that wouldnt lead to definitive answers.
