Where do we report that the last update gave a config change with grub boot loader? It borked my Proxmox install. I used grub doctor on parted magic and it was reporting that the bootloader required a UEFI bios. I've been running proxmox on a 1st gen I series and it is bios only. I also have issues with clonezilla cloning the drove. It keeps do ing the drive over and over.
