Ok I know this question has been beat to death many times over. Ok I'm building a new computer in a few weeks and want to get a few things cleared up. I already have a computer with everything installed on my WD blue 1tb hard drive. Im buying an ssd for fresh install of OS. Can I still just plug in my hard drive and access my programs after installing OS on ssd with hard drive unplugged of course. I have windows 7 on hard drive but will have windows 8.1 on SSD. Im not transferring anything over to the ssd it will just be windows 8.1 on there. What do I need to do to make this work step-by-step?
