A couple of days ago I could not get my system to boot. The fault was leading me to think that my hard drive (C:) had failed. I could, however, access DOS, and by doing so, I was surprised, when searching on C, and D, drives (I have 2 x 500Gig hard drives) to find that the drive letters had changed and that my C: drive, with windows, was now showing as D:, and vice versa.
I managed to fix my problem by going into BIOS and pointing the system to Windows on the, now, D: drive. The machine booted up and all was well.
Now, though, the system is showing Windows on the C: drive again and the order of my drives now appears back to normal.
Any thoughts on what happened to cause the initial problem? Has the system defaulted the system drive back to C: because windows is on it?
Just trying to understand what went wrong.
