I have tried Windows XP AND Fedora Core 2 to see if my cd-rom was bootable but all it does is gives me an error message that it can't read it. I can install any OS just fine on that cd-rom as long as I have a boot disk. My husband's computer will boot both of those CDs so I don't think there is anything wrong with the CDs. I have two CD-roms...one is CD-RW and another is just plain CD-rom. They both are using the same cable connecting to the computer. Do you think that could interfer the cd-rom booting? Sometime I wonder. I will try the Smart boot manager first and if that doesn't work, I will try other suggestions. Thanks for the Advices!
