I have a Friend I'm trying to introduce to Ubunutu but I'm having trouble installing on his system. New empty HDD, but the system fails to load the 8.04 Live CD, it drops to Busybox initramfs> prompt. However, it loads the 7.10 Live CD normally. I could install 7.10 and do a dist upgrade, but if there is some compatibility problem I'll be stack after the dist upgrade. How can I figure out whats wrong with the 8.04 install?

I should note that the system boots normally with a windows install, and I have burned the Hardy live CD 3 times, while the Gutsy Live CD work normally. I re-downloaded the Hardy Image and still no luck.
