A while ago, I got a Knoppix disc so I could use Linux apps on my Windows computer. I liked it so much, I decided to install is on my Mandrake Linux computer. However, whenever I try to boot it, it scans my drives and tells me that it can't find the Knoppx filesystem. I would attribute this to cd error, but the same disc works fine on my Windows computer.

Why would Knoppix not be able to find its own filesystem?
