Computer First Aid Using Knoppix

Windows just crashed. The computer won't boot back up. Those "System Recovery Disks" that came with your computer will erase all of your data. In most cases, when Windows breaks and will not start up again, none of your data has been lost, you just don't have a way to get to it. These instructions are a way of getting to your data when Windows won't work.
