I received a blue screen once and when I restarted, I saw that the system file was corrupt or missing in the windows directory. I followed the instructions to replace it using the windows disk. Then, NTFS.sys was corrupt or missing. This time, the recovery console froze after I selected the system drive I wanted to work on, and did this every time. I booted up using an old drive with Windows XP. It can detect the drive I wanted to work on as a different letter and can even access it and read the initial C:/ directory structure. Then, for some reason, windows started locking up and I couldn't go any farther.
Any suggestions? Is there a way to diagnose/check the drive integrity?
