Norton Ghost 15 sp 1 and Windows 7 - Clone Disk

Hi guys, new to the forum but i need to ask this question as it is really making me scratch my head!!

I hate to drag up an old chestnut, and from trawling the internet for hours to solve this i have resorted to asking here - yeah i have checked here and still no closer to help!

Ok, so i have cloned my laptop's hard drive which is running Windows 7 onto a new hard drive and windows is telling me that it is not genuine, giving me a blue desktop.  Using task manager i can run programs, however i can't re arm windows nor can i enter product codes.

I have cloned the SRP first setting it active and copying the MBR.  I then copy the Windows 7 Partition again copying the MBR, i originally couldn't get Windows to boot ut now can't get it to realise that it is genuine!!!

Any help would be brilliant, sadly i can't use a CD to restore or fix Windows as the machine has no CD-Drive

Cheers
