ghost 15 - drive won't boot

I bought ghost 15 expecting to be able to get an image of my laptop hard drive and store it on a 500GB USB hard drive - which it looks like it worked ok. I had ghost loaded on my desktop and used an ide usb adapter to connect to the drive when saving to the 500GB drive(creating a restore point). After an adware/spyware debacle I had to try to reload the image. It goes past the BIOS messages and then just have a blank screen. Any suggestions? Should it work the way I did it? Is there any recovering if not?
