While working on a project I was suddenly informed by windows 8 that it ABSOLUTELY just HAD to reset to install updates, and I had 15 minutes to comply. So I save my stuff and click "update and restart". My computer starts installing updates, gets to 30%, then shuts down. I hear 2 quick beeps from the motherboard speaker and it starts up again showing "repairing disk errors", along with a message informing me that this could take an hour. This has now been about 4 hours ago. The disk activity lights have long since stopped blinking and it's sitting there keeping my files hostage. What should I do to repair this? The computer is less then a year old with a hard disk with about 1.8TB space. The motherboard is an Asus Sabertooth Z77. I haven't touched anything on my PC and it's currently still on showing the same image.
Restarting the system brought me to auto repair, it failed and brought me to a repair menu. Can't boot in safe mode or use any restore option. Command prompt shows the entire C: drive to be renamed to the D: drive and I'm currently running chkdsk /r/f on it.
