I have a lap top that a friend of mine would like me to fix. It is giving a blue screen on boot up. When I looked up the error message it indicates that I should run a check disk.
Is this dangerous? Should I try to off load stuff from the hard drive first?
I ask because I had a hard drive of my own that when I ran check disk it wiped a bunch of "bad sectors" and I lost most of the info on it (but it had been going bad).
