I've disconnected everything except the main HD and the video card. No other
cards or drives are in the box. I get the same result. I'll try killing USB next.

Did it with -f and it was clean.

The error is along the lines of some of the devices have failed to mount. I'm
assuming that when the rescue disc boots, it reads the fstab on the drive it's
trying to mount and use them. The only one which looks like it's failed to
mount is /dev/hda1 which is where the /boot directory is.
