Okay. My little brother was on my dad's computer. He was playing a flash game and listening to music on WMP. Suddenly, WMP came up with an error saying the media was corrupt, and the blue screen of death came up. I didn't see what the blue screen's error was, but when the computer reset, it came up with "Boot Device Not Found".
We reset the computer manually, letting it sit for a minute unplugged. It booted up slower than normal, but otherwise properly. We then ran chkdsk, it said that the Master File Table's BITMAP was incorrect. We then ran chkdsk /scan as it told us to, and it said there were no errors in the filesystem.
Are the errors gone? If not, what should I do to fix them?
