I ran into a similar problem,the install would read from the cd and all of a sudden it couldn't read any more.
I tried a different cd rom and it went fine.
It seemed the other cd rom was going bad.

Everyone seems to be missing the point that some PCs do not have BIOS that boot from CD, and the CD is supported via an installed driver which is no longer recognized as you are trying to install a new O/S!
In trying to take an IBM 560X with Win98 and an aftermarket CD and upgrade it to Win2k for my daughter, the W2k installation CD would start to read and then get to a point where it would no longer find the CD to continue reading. Using a W2k install floppy set was no help either, as eventually it would look for the W2K CD and not find it. I finally gave up and left it at Win98. Neither IBM nor Microsoft could provide a solution for me!
