so, my c: crashed, it had xp pro on it. i thought "great time to upgrade". grabbed a dell oem disc w7-32 and loaded it on a new drive (no previous os). questions, will i have a problem registering the "upgrade to w7 pro"? can i use my xp pro key with an "upgrade key? or will i have to buy a full version of w7?
The copy of win7 that I got from the University i go to was an upgrade disk that could run on its own. (It was very weird as you had to install win7 with the disk, then upgrade win7 with the disk to make it legit)
However I have done some trouble shooting for people before and have found that an upgrade will only work from inside windows. So you have to run windows then pop the disk in and the upgrade will take over from there but you cannot boot to the disk and then do an "upgrade".
If you have an upgrade disk my advice would be to install xp pro on the empty drive first, then from your fresh copy of win XP do the win 7 upgrade. Not the quickest process I know but that is how the upgrade version of win7 was designed to work so it should be less fussy doing it that way.
