Alright, so I have a 200gb hard drive that is pre-installed in my laptop. Now I have a 1tb that I haven't put in yet due to a issue I think I will run into. If I take out that 200gb, I know I will lose all my games, pictures, music, but will I have to buy a new copy of windows 10? Or will it automatically activate on my new 1tb hard drive? And if It doesn't do it automatically what is the best way to put windows on that drive without buying a whole new key?
