I don't think it'll quite work that way. You can't run Ghost to rewrite the drive you're on. So you don't need to put another OS on the new drive. What you need to do is boot up with a special Ghost floppy. I assume you backed it up to, another PC? or DVD? I think in Ghost you can map a drive to where your image is & restore it. I have it & have done drive to drive "restores" with floppy boot, so it really depends on where you put your "image".
