I have Proxmox 8.1 running on a legacy HP Z400 workstation. It is booting to BIOS, not UEFI the box does not support HEFI. It has been working fine with no issues until I installed the upgrades last night. Now it boots to Grub Rescue.

Attempting to Boot From Hard Disk
Grub loading...
Welcome to Grub!

error: no such device
error: unknown filesystem


I have tried multiple ideas from the Proxmox site with no success. When I boot using the debug I can run a blkid command and I can see the disks. That is as far as I have gotten.

I think my issue is unique because all the troubleshooting tips are for UEFI-enabled boxes.

Any assistance would be appreciated.
