I purchased the upgrade DVD for Windows 7 Home Premium in order to upgrade my Windows XP machine. I really want to do a clean install as my machine has been running XP for a long time and there is a lot of cruft that I don't want to carry along. When I attempt to boot from the DVD I get an "error code 5". I also have a Windows Vista SP1 DVD which boots just fine so I assume that there are no problems with my DVD drive (Sony DVD-RW drive) or my BIOS (VIA K8M800 running AMI BIOS 3.7 which is the latest). I have tried all different booting options to attempt to get the DVD to start the install.
I gave up on the DVD and tried to do the upgrade via a USB thumb drive by following the steps at http://www.winsupersite.com/win7/upgrade_03.asp. Every time I boot with USB drive in place I get a message stating that there is no boot record. The USB drive is a 8GB Sandisk Cruiser with the U3 stuff uninstalled.
If anyone can help with either the DVD or USB install it would be much appreciated. Thanks!
