I'd try running the cloned drive on the desktop it works on and sysprep it. Sysprep on XP was a bit hit and miss with the way it handled pre-installed drivers, so you may get lucky, or you may not. You may want to try uninstalling most of them on the desktop, before the sysprep. When it's shut itself down, plonk it into the laptop and turn it on. It'll then start up like it's booting for the first time, so you may get lucky and that fixes it.

 

Obviously you'll then need to put all of the correct drivers onto it, and activate it with a key.

Yes. Boot UBCD4Win and run FixHDC - this replaces the hard disk controller drivers on the old copy of Windows with ones that work with the current hardware. It's never failed for me.

Of course you'll have to make a UBCD4Win (or you could use another BartPE disk) first, but you'll never regret that. It's the most useful system fixing disk ever.
