So I have am currently running Windows Vista 64-bit with a 500 GB hard drive. Recently got another hard drive that was in a different computer, and it have Windows 7 64-bit on it. That hard drive is barely used, about 35 GB. I was wondering if there is a way that I can get that Windows 7 on my original hard drive to replace Vista which is on it. When briefly looked up how to do this, there was a lot of mention about cloning. But the problem is that I have a lot of stuff on my hard drive that I don't want to move. And as I understood it, cloning the new hard drive and placing it on my old one would replace all the stuff on it. So does anyone know if there is a way to just get Windows 7 on my original hard drive? I am not opposed to having to re-install all the stuff on my original drive, I would just rather not. And if someone could describe cloning a little bit more in depth that would be great too. Thanks!
