Installing Upgrade on new Build Tags: New Build Clean Install Windows XP Windows 7 Last response: January 29, 2011 2:07 PM in Windows 7 Share rlu929s January 29, 2011 1:14:32 PM I just finished a new build using the following link. http://www.tomshardware.com/forum/forum2.php?config=tom... System runs awesome! However, I can't get Win 7 installed. I have a retail 7 Upgrade disc. I have a couple copies of XP that should allow me to Upgrade. I tried doing a clean install and it never asked for the disc. It wouldn't take my key though and I read it's because you must have XP already installed (dumb). Some I'm trying to install XP on my machine and get a BSOD once it loads all the drivers and starts win setup. It says PCI.sys Address F748E08F base at F7487000 So, What do I do at this point. I wish you could just stick the disc in and do a clean install. The 7 Upgrade did work fine, but wouldn't take the key even though I knew it was right.

The first time, do not use the license key. During the 2nd install, you should be able to input that license key. | Report abuse WR2 Windows 7 Authority January 29, 2011 2:07:32 PM Here is a link to more details and explanations.
