Not 100% sure why it won't boot, but will the fact that one drive is PATA and the other is SATA make a difference?
Try using this CD:

If that doesn't work, there are some free cloning programs on the disk, try using them instead of Norton Ghost, see if that fixes this booting issue.
EDIT: Just read LoadWB's post. I don't really know much about HD cloning so I'd recommend following LoadWB's advice.
