Hi,

I am reformatting my desktop and had a question on installing the OS.

Originally, this system had XP and I used a Win7 Ultimate upgrade disc. I can only find the upgrade disc and not XP at the moment...

What I do have is a copy of a Win7 Professional OEM System Builder which is installed on a different computer.

Can I somehow get back to my original setup on the first desktop? (Win 7 Ultimate)

TIA
