Hi:
That happened to me once using recovery disks on a HP 8000 Elite business desktop PC.
I tried every trick in the book to no avail.
I ended up having to use a plain W7 installation disk and used the product key from the PC's case to activate the installation.
No problems whatsoever with anything with a clean install from a standard W7 DVD.
You can make your own if you don't have one.
If no one can come up with a better solution, and if you don't have a Windows 7 Home Premium 64 bit upgrade or OEM installation disk, let me know, and I will give you the links to the W7 ISO file downloads and the tool needed to make the ISO file bootable onto a DVD or 4 GB USB flash drive.
