I had a similar problem about a year ago. First trying out linux, using a red hat boxed set, 9.0 as well. Halfway through the installation it gave up. It turns out there was a bug in the install program or something, so I contacted red hat and they sent me new disks at no charge in about 2 days. Worked like a charm. If you bought a set too, try asking for new disks, or try d/l them and burning them. Or, check your media, disk space, and hardware as the install suggests, if you haven't already. Hope this helps.
