[Problem] BlInitializeLibrary failed 0xc0000001 when trying to install Windows 7 on UEFI x570

Operating Systems Windows 7/Vista/Server 2008

Hello. I use a Gigabyte X570 Aorus Master on the latest BIOS. Windows 7 works fine on CSM but i have to use UEFI now since i got a 980 PRO 2TB and i need GPT. I made my installation media on a USB stick with Rufus selecting GPT and UEFI only. I tried renaming the bootmgfw.efi to bootx64.efi on \efi\BOOT. Tried using UefiSeven. I played with UefiSeven settings to get verbose boot. But it always ends
on the “BlInitializeLibrary failed 0xc0000001” message

Is there any way to clean install Windows 7 on UEFI and GPT x570 systems?. Maybe some BIOS settings i need to change?

Maybe >this< Microsoft Community statement will help you to solve the problem.
By the way - your chosen thread title has a typo and may be misleading. It is the B1InitializeLibrary, which failed.

Oh, i checked but it seems its actually an L instead of 1.

I followed the steps in that page but still nothing :frowning:

Now i tried downgrading the BIOS to version F30 and the error code changes to 0xc000009a, pretty weird
