You should be able to install now. I have always done that and never had a failure.
Yea thats good, the only problem that was messing me up though, was that the vista wasnt bootable. It was supposed to be, but just wouldnt. So I had to do it from my other windows. But yea, what you suggest would of worked perfect.
