I had this trouble once before and for the life of me, cannot remember the solution. The problem with old age is, I can remember everything 40 years ago - anyone want some help with the Commodore Pet?
I had some malware so reloaded Ubuntu 13.04 and within a couple of seconds of turning the computer on, I get the following error message
error: unknown filesystem.
Alas, the only way I can get to my data is to load up the live disk, and you all know how long that takes. I am slowly dying here of caffeine poisoning during the daytime and alcohol poising during the evening.
Any clues? I downloaded the boot repair disk, but that doesn't boot.
