Problems Ghosting server 2003!

I am having problems ghosting a 2003 server.  I have created the image and it seems to be fine.  I then load the image onto a new hard drive and test the hard drive to make sure the image is working and it will start to load then go to a gray server 2003 screen and it seems to just pause for 20 seconds to a min. then the computer restarts.  Any ideas?
