I have an old PC running on a 486, not sure about RAM or anything else. I recently dug it out of the attic and thought that i would wipe the hard drive (407 mB) and install Red Hat Linux 7.2. I formatted the C: drive, and it then gave me a message saying "Warning, possilbe virus detection, continue?" i said "yes" and it the asked me to name the drive, if i remember correctly. My computer then froze, and I had to reboot. When it was starting up, it gave me a "non-system disk error" because I had left a floppy in the drive. I took it out, but it still gave me the error. So i rebooted a couple of times but the same thing happened. At this point, I was annoyed, so i took the box apart, and removed the floppy. Then I changed the BIOS so that it didn't think there were any floppy drives, though there was still a CD drive now plugged in the cable that had been attached to the 3 1/2 floppy.....any suggestions as to a way i can fix this, because it's still giving me the error.
