I've followed the instructions here GNU GRUB Terminal - Instead of Ubuntu login screen but it can't read any of the disks.
I'm getting 'Filesystem is unknown', 'filesystem is ext2' etc.
It's a server edition install. I stupidly selected LVM and was interrupted during the install. However, I can't now get back to bios to reset the boot order and reinstall.
Below is an image of the output from grub> ls I can't copy and paste, as the machine is well and truly stuck.
