Proxmox 7.2-11 - Windows VM with OVMF (UEFI) cannot load Virtio Drivers

[Mecanik]

Hi, as the title says I cannot load any virtio drivers during installation when using UEFI mode. I am using the latest drivers (stable) available.



VM Config:

bios: ovmf
boot: order=scsi0;ide2;net0;ide0
cores: 2
efidisk0: local:104/vm-104-disk-0.qcow2,efitype=4m,pre-enrolled-keys=1,size=528K

I have tested Win 8, 8.1, 10 etc... none of them working.

Am I missing something? Please advise.

Thanks

I would like to better clarify with an update:

• Windows 8 x64/x86 - unable to load drivers
• Windows 8.1 x64/x86 - unable to load drivers
• Windows 10 x64/x86 - does not boot at all
• Windows 11 x64 - Install OK (surprisingly, drivers were loaded OK)

Regarding the Windows 10 not boot problem:

OVMF (UEFI) not supporting x32: https://forum.proxmox.com/threads/uefi-windows-10-32-bits-iso.107591/post-462596

Unable to load driver problem: https://forum.proxmox.com/threads/can-not-install-windows-2019.75479/post-336268 BUT use the virtio-win-0.1.185 drivers and problem solved. Latest ones are not working.

Wish I hadn't waste a full day on this.
