Hello all, I have a PC AMD and one day I fired it up and I was not able to reboot, it asked to reboot from DVD but I lost my ISO copy when I moved and don't have the product key either. I think it was win 7 but not sure if it was pro or ultimate. I have installed cs5 and files that I need. Can I install a new version of win 7 ultimate on top of the current one? I have a new win 7 ultimate but I'm not sure if I can repair the current one or just do a fresh install and if so, will that delete my cs5 and my files.
