I had a C drive(30G) and a D drive(7G). The computer froze and I had to shut it. I could not reboot. Invalid system disc. I have Norton ghost and tried to recover using the backup discs but it would only show the D drive. I checked the bios and it shows the 30G drive as not installed and I only have the 7G drive. Anyone know how I can recover my original C drive or any of its files?
