I spent 3 hours on the phone last night trying to get an Nvidia graphics driver to run. It keeps saying that I'm not running Vista and the driver only works on Vista. But I am obviously.

Apparently when I did the Home Premium upgrade, it did not dispose of the old XP recovery console, and Vista now thinks its a seperate OS on my hard drive. My computer boots to Windows Boot Manager and asks which version of windows I would like to run, but I know that there is only 1 on it.

Is there anyway to do a fresh install with an Upgrade disc? or do I have to buy the full version?
