Knoppix is intended to run from the Live CD. Installing it is not always wise and certainly not something that needed to be or should have been done for a data recovery opeation. Just the opposite, installing Knoppix is a very bad idea when you are dealing with disk problems and trying to recover as much as you can from the hard disk.
