I have both Windows 2000 pro and knoppix3.7 lloaded on different partitions of the first HDD ( Hda1 & Hda2). I put Lilo into the MBR, and get a choice of operating systems when the Debian LILO screen comes up. Now I'm thinking about taking Knoppix off and Installing Mandrake to try it out, but I'm concerned about what may happen to my MBR. Is there a way to Uninstall Knoppix in such a way that Lilo will be safely removed from the MBR ?
