Win 2k Pro Cloned Hardrive Boot Errors

Okay, this question is a little complicated, hopefully someone will make sense of it and have some advice. I recently got my own computer, and i didn't want to start over again with the hardrive, because of all my programs and settings. So I decided to clone the new drive from the old one, and used norton ghost 2002 to do so. I slaved the new drive in the old machine, and proceeded to succesfully clone the drive, leaving me with what should have been two identical drives. I took the new drive out, and put it back into it's host machine, and proceeded to boot. After getting all the way to the graphical windows 2k boot screen(2nd one), i get a blue screen with a long explanation saying that this drive is unbootable, with a long list of instructions afterwards. Suggestions it gives are restart to see if error dissapears, run scandisk, or chkdsk to look for drive problems or remove any new hardrive hardware recently installed. Tried the first two, don't see any reason to do the last one, since this is my bootable drive. Am going to re clone the drive as a last resort soon, but hoping to find a solution to save that hassle. Does anyone have an idea why i get this boot error, when the drive it was cloned from works perfectly?? Any help would be greatly appreciated!!!!
Thanks.

 

What you did sometimes works and sometimes doesn't. The recommended way of doing it is rather complicated - see MS Knowledge Base Article ID: Q249694. Try a repair install.
