BACKGROUND

I have a friend with a 486. The HD is something like 800 MB, so he uses
OnTrack disk manager. While swapping out cards, installing drivers for new
peripherals, etc., at some point something was corrupted and the system quit
working. I forget exactly what the symptoms were, but hopefully that is not
essential to my question.

Eventually he decided to format drive C and start over. He typed format c: and
then installed Win95, which proceeded normally. However, when restarting the
computer for the first time, he got "DDO integrity error. Reboot from
diskette." When rebooting from the diskette it said something like "Win95 is
not designed to work with DOS 6.x" (That I can understand, since he was using
an old floppy. I told him try your Win95 startup floppy and see what it does.
He is going to try that.) He formatted again, installed Win95 again, and still
got the DDO integrity error.

QUESTION

Is this DDO integrity error message related in some way to OnTrack? If so, why
didn't reformatting get rid of it? What needs to be done to allow the computer
to start normally? My friend would prefer to not use OnTrack, by the way, even
if it means not accessing the full capacity of the HD.
