GRUB error, possibly RAID-related, inability to boot
I'm trying to get a laptop up and running. I've already nuked everything from orbit and paved over with, nominally, a fully-encrypted Ubuntu install, and when I rebooted off of the Live CD to try to load Ubuntu, it gave me a grub rescue screen.
So of course, I try the obvious:
grub rescue> ls
Attempting to ls into each of those gives me "error: unknown filesystem".
Attempting to run the boot-repair utility or the rescatux/grub fixer programs doesn't work. The latter gives me a long, unending chain of disk I/O errors and the former complains of there being a RAID and doesn't supply a button with which to even start the repair.
... halp? I have no idea what I'm doing at this point, having completely exhausted my own knowledge.
I can boot up from a LiveCD just fine, it's booting from the HDD's install that fails.
If there's any additional information I should supply, please let me know.
