PBS restore not restoring efi disk

[UpAndRun]

I am running into restore problem. I have a Windows server 2025, the config has two zfs, one is restored as vm-101-disk-0, the EFI should restore a disk called vm-101-disk-1, but it never did.

The result is when I start the VM, it gives me error: TASK ERROR: timeout: no zvol device link for 'vm-101-disk-1' found after 300 sec.

Anything I did wrong? What do I need to do to fix this?

Here is the hardware list for the VM:

I'm running into the same issue.

I think I found the issue. If the VM is not using UEFI, when restoring from PBS the EFI disk will not be created on the target storage.

Hi,
thank you for the report! A patch to improve the restore behavior was proposed on the mailing list: https://lore.proxmox.com/pve-devel/20250304104413.38638-9-f.ebner@proxmox.com/T/#u

Yes, that is the reason. The disk is not attached to the VM and not included in the backup if the VM is not using OVMF BIOS.
