VM boot problems with OVMF UEFI BIOS

[fabiolanza]

Hi,

I am new to Proxmox. I create a Windows vm with SeaBIOS, and then I learnt that I need the OVMF UEFI bios to be able to use PCIe passthrough. I changed the BIOS to OVMF UEFI but I am getting an error, Windows is no longer booting.

I found a tutorial in the internet suggestion to go to the BIOS of the VM and add a Bood Option (EFI Application). I did that, but nothing comes up in the BIOS File Explorer.

On my VM hardware settings, I did add an EFI disk.

Any thoughts on how to fix this?

Thanks a lot!









Thanks,

Fabio

Hi,

If you installed Windows on a legacy bios it does not boot on an EFI environment.
Here is the Microsoft Doku for this.

Hi fabiolanze,

I'm seeing the same issue, were you able to find the solution? Any way I can use the existing installation of windows without creating a new VM?

Help much appreciated.

Thanks!
