If you can, try booting from the Drive Image CD and you should be able to do a Restore to copy the image file from F:\ back to C:\ that way.
Or you can boot with a floppy and then navigate to whatever drive letter is your CD and then use these commands:
Y (your drive letter):\CD\English\Execute (enter)
Y:\English\Execute\PQDI (enter)
and Drive Image should then load from the CD into DOS so you can run a Restore.
Note: I haven't used this method in quite a while so it may be Y:\English\Execute (enter) and then Y:\ PQDI (enter)
Just boot from a floppy, navigate to the CD drive letter and then do a DIR and if you can see the contents of the Drive Image CD those commands should work for you.
