I just got a Dell pc that was supposed to come with WIndows 7 Pro 64-bit OS but came with Windows 7 Pro 32-bit instead. Otherwise the machine is 64 bit ready. Dell sent me a Win 7 64-bit install disk. I have questions: 1. Do i merely boot up off the 64-bit dvd? 2. Will the setup automatically wipe out old version of Win 7 so it can do a clean install? 3. Will the Win 7 32 bit Easy Transfer be able to bring docs and setttings over to the 64 bit Win 7? Thanks.
