    So would it be possible to replace the vga.sys in the 7878 build with the omne in win7, or raname basicdisplay.sys to vga and use that instead?

    Lol I and @ExtremeGrief tried to install Windows 8 7880 on UEFI class 3, but without success, but also @ExtremeGrief tried to install Windows 8 7899 on UEFI class 3 with success, so, try to use basicdisplay.sys from Windows 8 7899 instead

    How did you get to to boot? It just crashes and gives an error message, this computer has encountered an error and needs to restart.

    BSOD? If it is BSOD (mostly common 0x000000A5 aka ACPI_BIOS_ERROR), then it is common in the late 78xx - early 83xx range

    But I am also wondering if FlashBoot Pro patched bootmgfw.efi can work with Windows Vista/2008, because I am mostly interesting in Windows Vista/2008 than in Windows XP/2003, 7/2008 R2, etc, and I am wondering if FlashBoot Pro patched bootmgfw.efi can work with it, but we have another problem... Haswell+ clock drift bug and Ryzen bluescreening

    We should first try to get 7 flawlessly working on UEFI, then try Vista or earlier..

    I'll try to post a picture soon. It
    Yes I think that was it. I'll try to get a screenshot at some point. So what are our options then if that is the case?

    Yup it's that error. I'm trying to run it on my Surface Pro 3. Is there any recourse?

    You probably need to patch acpi.sys, but we don't know how to patch Windows 8 beta acpi.sys

    BTW, someone on MSFN was got Windows Vista working on UEFI class 3, but however, he was used UefiSeven to boot Vista, and also he installed it on Sandy Bridge (or Ivy Bridge, but we don't know exactly)

    I think Windows 7 ACPI patch works but he could try to just copy Windows 8 ACPI

    I guess I'm lucky to be able to run any Vista+ OS on latest BIOS on my B450 motherboard :)

    But anyway, it is so weird that Windows 7/2008 R2 can work on most modern hardware, but not 8/2012 beta (late 78xx-early 83xx)

    Maybe because you have a PC from 2010-2012
