Vista 64 Ult Hanging on install "Completing install" stage. Please Help

I have Vista ULT. I've tried to install about 5 times and every time it crashes at the 'completing installation' phase.
I'm doing a clean install. I have even deleted the HDD partition and re-made it into 2 partition, and then tried installed it but with no joy.

I'm am just trying a full format instead of a quick to see if that makes any difference?

Have tried setting all BIOS settings to default and removed all USB cables apart from Mouse and Key board.

I am not sure why i am having this problem as it installed fine the first time i installed it? :angst:

Cheers

Did you load any custom IDE/SATA drivers?

Have you run a chkdsk?

LOL! don't believe it.... was going to try it at the start but thought it wouldn't be the coursing the problem tbh.... But it was!

Solution = Full format not Quick.

Cheers guys for the quick replies !
