Hello, yesterday I made a mistake in which I changed some of the directory files for a game on my computer, the next day I try and turn my PC on but all I get is a Black Screen with no cursor or Bios or anything, I literally am unable to do anything. So I installed windows onto a usb, removed my original boot drive and used the usb to boot. After installing windows on a new drive I tried putting the original drive back in, but again, I have a black screen. Is there anyway for me to save the hard drive and what's on it?
