I have a bought Knoppix 4.0 DVD that won't boot. Thr computer is a stock 1.0 g NetVista IBM, and the Bios is set for 'CD' first and hard drive last. Nonetheless, it skips over the 4.0 DVD and starts on the system on the hard drive (KnoppMyth) The computer has a CD player as #1, and a DVD burner as #2. A 'live CD system (Mepis) will boot from either one, obviously, the DVD has to be in the DVD burner, but every config I've tried for the drives, skips to boot the HD. I can read the DVD, running from another system, but I can't figure how to make it boot.
