Hello. I'm new at using knoppix. I'm trying to fix a friend's computer. When I turn on the computer, it simply says "No operating system detected." I figured I would try booting into knoppix so we could back up his files before I tried anything else, but I can't even seem to boot into knoppix. At the loading screen, it gets stuck on the second line: "Looking for CDROM in: /dev/hda"

Also interesting: at the top of same screen, it says "hda: INVALID GEOMETRY: 0 PHYSICAL HEADS?"

It almost seems as though whatever is up with the hard drive is affecting knoppix somehow? But I thought knoppix ran exclusive of the hard drive entirely?

Any suggestions?

Thanks in advance.
