First off, thanks in advance for any response to this post. I want to format a hard drive from my old computer and install in my new build. The old hdd has Windows 7 ultimate on it and the new computer has Windows 7 on it(not sure of the version). When I install my old drive which version of Windows will boot. I don't want any data from the old drive. Will I have an option during the boot sequence. Also will need help setting up the drive, but will post that question when I get to that step. Thanks
