Also, GHOST can be run from a floppy disk. You can create this disk from the program. So in the event that you have to reload your OS and programs, then just bootup your PC from floppy using your WINDOWS startup diskette. Switch to the GHOST floppy, run it and reload everything. Then in a few minutes, your system is back to normal.
There is a reason why GHOST is so popular among savvy computer users. I think there are other companies that might provide this free UTILITY program but I'm not sure. Just check at CNET website.
