I'm a Mac user helping out a friend, so I don't know much about Windows. They have a Windows Home Server that their PC backs up to. The docs for Windows 7 64 bit say that it needs to be a clean install, and that you have to restore user files after installing. Is the WHS backup (created by a 32-bit OS) sufficient to restore from? Or do I need to somehow manually copy their documents, programs, etc. to a backup drive before wiping?
