Whenever I start Windows, a black screen comes up and I can't do anything other than shutting down my PC. I tried starting Safe Mode from the Boot option directly after the computer started but it looked really confusing and I didn't see anything with Safe Mode written on it. I selected the first one and the screen went black again. After shutting down, it said "disk read error occurred" or something liked that. It told to to restart pressing CTRL+ALT+DEL. The screen went black again and then after a long time, the screen for the automatic repair loading screen started loading. After that, nothing happened. What do I do? I just want to use my computer!
