Can you boot the computer from a linux boot disc like Knoppix, SystemRescueCD,...?

If yes, can you mount and access the partition from there? Common cause of this error is missing SATA driver or missing filesystem support in the kernel. Since the message states (8,2) instead of (0,0), I'm guessing missing filesystem support or a damaged filesystem.
