I have installed Windows 7 from my PC to my Mac using Parallels 7 and it works fine. I have been using the PC for another operating system. I am having problems with the Mac that Tech support cannot resolve and they want me to take it to the Genius bar so they can wipe the drive and reinstall Lion. My question is, is there a way to reinstall Windows 7 back to my PC using Parallels or another program? I would hate to lose all my work.
