I got a problem here with my laptop. I was using it today and it was lagging so I restarted it. When it was restarting, it got to the login screen and then suddenly went to a blue screen saying "STOP: c000021a Unknown Hard Error". After trying to restart the computer in safe mode with and without DOS, I still got the same message.


Then I tried starting it up again normally, and I got a "Unmountable_Boot_Volume" message. Can anyone tell me what's wrong with it? And could the files on the hard drive be saved?


Thx for your time in advance,
