I had this problem last night when installing 8.1 It may be fixed in cooker, but just in case....
When installing Mandrake on a mixed system, SCSI and IDE drives, and the system is set to boot off the SCSI drives, LILO writes the boot device as /dev/hdc. It should be /dev/sda. The bios is set to boot off the SCSI and the system was booting off the SCSI until I installed Mandrake. I fixed the "boot=" in lilo.conf and it works fine now.... Steve
