Initial Goal: Reformat hard drive and reinstall Windows XP.
New Goal: Make Windows XP Setup go away. Install Windows 7.
The process ran smoothly until Setup asked for a product key. We entered what we thought was the product key (obtained from My Computer before reformatting), only to discover that the Product ID and Product Key are not the same thing. We couldn't find the product key, so we decided to do Windows 7 instead.
The problem is that we can't run Windows 7 Setup because Windows XP Setup keeps starting.
We told the BIOS to boot from CD. That didn't work.
We reset the NVRAM. That didn't work.
With the XP disc in the drive, we held down the Shift key to bypass everything. That worked, and allowed us to boot from CD, but then Setup failed when it found that PCI.SYS was corrupt.
All we want to do is kill the XP Setup so we can start the Win7 Setup. Any and all help will be appreciated.
