Is this using a DVD drive by chance? I've had the same problems (albeit with
8.x) while using my DVD drive. The solution was for me to restart
installation on my secondary (cdrw) drive.
I'm not sure if that will help or not, but it might.
Another thing to do:
make SURE your cd rom is supported (it should be, most basic cdroms are)
