I must reinstall the OS. My problems are getting way out of hand. I have two optical drives, a NEC and a Lite-On. My install media checks out fine. When I set the bios to boot from the NEC, it boots the install disk and I can start the installation. The installation hangs, however, so I'd like to try to install from the Lite-On. When I set the bios to install from the Lite-On, it acts as if the disk is not an install medium and tries to boot from the hard drive. This happens with the FC5 install disk, with a known-good Kubuntu install disk, and with a known-good Slax: so the problem is not in the medium. What can I check to see why the Lite-On does not recognise bootable disks? Thanks in advance. Dotan Cohen ¬ http://what-is-what.com ¬
