So I ordered new pc parts for my new build and I was wondering if I can reuse my old hard drive from my previous dell computer. It is a seagate 500 GB Hard drive. I also ordered a new copy of windows 7 since I heard you can't boot up the hard drive with a previous oem operating system. So will it work with my old hard drive with my new copy of windows 7?
