vista install over xp

Hi there,
I have a Vista capable PC but I don't have a DVD-ROM drive readily available. I want to upgrade a test PC that currently has XP Pro to Vista beta 2. I have the Vista ISO and the DVD available on a different PC, so I should be able to map to it and install over XP (I think!) I don't care about keeping the XP data--it can be all wiped out. It's a test PC.
I did this before and Vista setup created an "OldWin" folder that had everything from XP in it. It's huge and I want to delete that folder, but when I tried this last time, it hosed the bootup process. When I restarted the PC I got a "Insert Boot disk" error... Shouldn't I be able to remove that OldWin folder?

I think the time and effort you have already spent to on this seems much more time consuming than buying a $20 DVD-Rom. If you try to make things harder than they have to be then you will have problems in the long run.
