VM won't boot after I lost some cached files "Minimal BASH like line editing is supported GRUB"

Featured Replies

Hello, this morning I could no longer log into my debian VM via ssh; vnc was fine. I don't know why as the recent changes only included installing pihole on UNRAID and a nextcloud, maridb, phpmyadmin docker services into the VM.

 

While looking into the problem I found out that my cache had 230Gb used since multiple days (only .2 Gb added removed) even tho the mover is supposed to run every 6h and i ran it manually. So i had the brillant idea to go on my unraid terminal and type a 'rm -r /mnt/cache/*' out of frustration thinking i should not have such important stuff cached and that i needed to start working a fresh environment.

 

Well now my VM won't boot at all, and when connecting through VNC I got this message from GRUB:

Fix Minimal BASH like line editing is supported GRUB

 

I have some backups fortunately; but i have not enough free space on my array ATM to create another VM and restore things. And i don't want to fully erase that one until i fix things. So I'm desperately looking into ways to fix this VM. I found multiple source all sugggesting to use a live USB but I guess I cannot go with that as it's a VM but I'm not sure of anything and would prefer some wise advices before i dig more of this grave I started with the dumb rm.

 

EDIT: I want to try the steps described here but i'm scared to not choose correct partition. Can someone give some insight here ?
