Hello,
This would not be caused by SP1. At all. If he can not load from the disc by booting then there is something else wrong. A check disk should be done. Cause if he is trying to load right from the DVD to install fresh then the previous install would not affect it at all. Which means that there is something far worse wrong with the machine. Not just having SP1 installed.
Run Memtest86 and do a check disk.
Cheers,
Mak
