Ok, so I want to buy an m.2 memory card. I have seen multiple videos instructing me on how to clone my current windows to the new m.3. My question is how to I delete Windows and ONLY Windows from the old hard drive after I have cloned the OS. I plan on keeping that hard drive in my pc to hold my games and such and do not want to format it bc it has a lot of important stuff. So is it possible to ONLY delete the windows stuff from the old hard drive?
