I have a distribution called Easy Peasy on my netbook, it's Ubuntu-based.
Today when I started it up it told me 'grub corrupt'. On subsequent start-ups it displays 'unknown filesystem.' I'm given a prompt labelled 'grub-rescue>' but I can't get any commands to work (even just 'help').
I've tried booting off a Live CD of Easy Peasy. That works fine, but I can't get to my files. I've tried using a program called photorec and it can recover files from the drive but it dumps out gigs upon gigs of unlabelled files, many of which are things like system files or web browser cache -- I only have a few dozen text files I actually need, so this is pretty unworkable.
I'm trying to reinstall grub, which I understand to be part of the booting process, but I've had no luck; any set of instructions I've followed has inevitably run into some error or a step I don't understand.
How can I get at my files in an easy to recognise way (such that I can navigate the original directories and get what I want)?
How can I easily reinstall grub such that I can just use the system like before without having to reinstall everything and lose my files?
I think my drive is sda or sda0. In grub's device.map it's called hd0.
I have almost no linux knowledge. Simple steps would be much appreciated.
