Hello. I need some help. After a failed disk of my proxmox installation, I managed to clone the disk to a new one, but unfortunately I can't boot. I am stuck at the grub rescue. I tried the proxmox grub rescue guide but when I try to mount the boot directory, In order to chroot the installation and repair the grub, I get error of unknown filesystem type and it doesn't mount it, so I can't chroot. Now what? Am I totally lost? I really don't want to set everything from scratch. Don't ask about any backup. Completely my fault.
