Hey, I have a computer that a small custom gaming PC company built. I have a CD that says Windows 8.1 or whatever and a little label on the back of my PC with the product key. I have a 3TB HDD with 230GB of files and OS on it, and I want to move my OS and some of my main apps (but not all my files) to a new 850 EVO 250GB SSD. I have a spare 1TB HDD that I can use as well. What are the steps and process to do this? Thanks. P.S the SSD will be my boot drive.
