Hi, I will be building a PC here soon for the first time by myself without help. I currently have a 1 TB M.2 as a hard drive that has windows 10 from my old motherboard that failed on me. My question is when I go to reinstall a new windows, ( assuming I'm going to have to buy another copy for a new motherboard), Will it give me an option to reformat it? Or how does that work? Also, I would like to buy another hard drive to put the OS on, and keep the M.2 for all my games. Is it recommended to get another hard drive with the same speed as my current? And, how exactly does this work? I'm kinda lost.
