How to fix "error: unknown filesystem. grub rescue>
My Ubuntu 10.10 system suddenly froze/crashed for no reason and I had to hard reboot my computer. Surprisingly it doesn't load anymore and stay stuck on a grub rescue prompt after an "unknown filesystem" message. That was enough clues to start googling for solutions.
grub rescue > ls show me all partitions on hard drives :
(hd0) (hd0,5) (hd0,1) (hd1) (hd1,1) (hd1,2) (fd0)
According to all answers that I've already found, next logical step is to ls again the specific partition that contains the kernel, which is (hd0,1) in my case :
grub rescue > ls (hd0,1) unknown filesystem
So here's the problem : I can do a normal ls, but not ls a partition (I tried all of them, just to be sure)
Other (unrelated?) issue, I can't repair anything since all Linux Live CD i try stay stuck in an infinite loading splash screen. The one with small dots below ubuntu logo.
