why are you trying to install an old version like that?
RedHat is up to version 9 now (we won't go into details of current affairs with versions)
Have you tried Knoppix? If you're new it maybe a better option until you're more comfortable.
(
www.knoppix.org I believe)
So you put the CD in to boot to the CD but it doesn't boot?
How old is this laptop? OLDer machines did not have the ability to boot to CD
OR its not set correctly in your BIOS to boot first to CD
OR its a corrupted cd.
