BleepingComputer.com: Vista64 Ultimate Installation Issues

I just put together a new system and XP installed without issues. I did created a partition for Vista during the XP installation. When I reboot the system with the Vista disk in, I see the loading bar stating "Windows is loading file" and that completes without any issues. Instead of continuing the Vista installation, the pc reboots back to XP. If I hit a key to boot from CD when I get the chance, it starts the loading bar again.

This is my first attempt at installation Vista. I have seen a lot of threads where the loading bar freezes or takes forever to complete, but this isn't my issue. It runs through the loading bar in about a minute, it just doesn't get past this point.

According to the site where I bought the memory and the Corsair site, the memory should be 1.9V, but the memory label states 1.8V. I thought this might be an issue at first, but XP didn't have any issues at all.

GIGABYTE GA-EP45-UD3P
Intel Q9550 2.83Hz
2x2GB Corsair DDR2 800 1.9V 5-5-5-18
EVGA nVidia
GTX 260 896MB 55nm Core 216 Superclocked Edition
CORSAIR CMPSU-1000HX 1000W PSU
WD 500GB 32MB Cache

Turned out to be the installation disk. Borrowed a disk from a buddy and it installed just fine with no issues.
