Norton Ghost 11.5.1

I have a disk image (ghost) of the disk need to be restored, and believe the ghost.exe should run from bootable USB with DOS, but I can't seem to create it. My laptop does not have a a cd-rom or floppy drive.I managed to find a Ghost utility that I could load from a bootable USB drive. Unfortunately, when I plug in my NTFS external drive (USB), it is not detected.
