Windows 11 VM BIOS change anyone?

[chudak]

Hello

I have a Windows 11 VM that is using OVMF(UEFI) BIOS
Is it possible to change this VM to be able to use SeaBIOS BIOS?

TIA

yes in hardware option,
but Windows require boot loader adjustments, not really a Proxmox VE side.
edit2: GPT to MBR disk layout conversion required too.

edit: Windows 11 officially require UEFI but works in SeaBIOS (+ clean install / inplace upgrade from win10 require bypass)

Yes I saw that

I am interested in how to make it work for a VM that was setup with UEFI

Can you elaborate if you know the details?

I forget the mandatory disk layout conversion from GPT to MBR.
I can't help you on this topic on my free time, but you will find examples on the web.
It's same as Windows 10, switch from UEFI to Legacy/CSM.
Don't forget to backup VM before attemps.
