It worked fine on Arch. I finally found a flash drive and filesystem combination that the windows installer would both see and install when I put the manufacturer’s Windows 11 64 bit ahci drivers on. It was a scandisk usb 3.0 mini thumb drive and ntfs in case anyone was wondering. I have 7 other usb flash drives at my disposal, most of them I could see but not install the drivers and I tried ntfs, exfat and fat32 before giving up on each flash drive.

Try doing it on a b650 motherboard that’s so new the windows installer doesn’t even have the correct ahci drivers
