Hi. Today I was trying to install a windows VM and I, as a total newbie passthrough the integrated and only gpu to it. After starting the virtual machine, proxmox froze for a moment (jellyfin usually breaks my proxmox machine too when I try to use hardware enconding) so I unplugged the machine from the power outlet as I've done before and after restarting it noticed that I couldn't access the web UI. I plugged in a monitor and this message appears
Code:
Welcome to GRUB!
error: unknown filesystem.
grub rescue>
I tried following the steps from this wiki: https://pve.proxmox.com/wiki/Recover_From_Grub_Failure
But it didn't work, I'm very new to linux so I actually don't know what is wrong. I couldn't understand all the other grub related errors on the forum either, but I also think they don't apply to mi problem. Is there a way to fix this error or to at least recover or extract a VM from this broken installation? There is data there that I would like to keep.
