My laptop was freezing occasionally so I tried to shutdown and restart normally, and it wouldn't boot. Windows couldn't fix the error, so I went with reset keeping files. That failed. Now every time I restart the laptop it goes Preparing automatic repair > black screen where I can move my mouse > Diagnosing > Repairing disk errors. It is stuck here and left for over 6 hours. I have since hard reset multiple times to the same thing.
