On a formatted hard drive I loaded DOS 6.22 (3disks) I removed the last desk as per instructions and when it rebooted it said the following……
ERROR 1 LOADING OS. This may be due to a virus.
1. Shutdown
2. Boot from floppy
3. Run ONTRACK Disk Manager
4. Select “Upgrade” option from Main Menu

486 with win 3.11
Processor 486-WB-66-7MHz

Please can anyone help (if I have not supplied info let me know)
Thank you
David
