Yes, I made Windows 7 VM working with OVMF, but the question is, GPU driver post error code 12.
To successfully install Windows 7 iso, must be make the Fastboot Pro provided "bootmgfw.efi" into the installer iso's "install.wim", and install it use Windows 10 PE system.
My hardware:
CPU: Ryzen 3 4300G
Motherboard: Asrock B550 Phantom Gaming ITX
Grahpic card: Asrock RX 5500 XT Phantom Gaming
Sorry my bad english, I‘m not sure if there are any errors in my grammar.
bootmgfw.flashboot.efi
