HDD clone problem for my laptop

hi, all, I used Norton Ghost 15 to clone my old 320GB, which was originally installed in my EDGE15, to a new HDD (500GB). The clone process is fine, but the problem is after i installed the new HDD, and boot it into windows7 desktop, there is a line saying that "this is not a genuine copy of windows 7", and the desktop is blank (no icons and start-up menu) with blue background. so i wonder how to solve this thing, theres a win7 SN printed in the battery bay, but i dont know how to use it to verify the new HDD.

 

ps.  i tried open task Manager and start the explorer from there, and it did work somehow, meaning that a temporary win7 account is activated, but if i clicked "computer" in the start-up menu, a error message popped up "no such interface supported"; and if i right clicked "computer", nothing responsed, nothing show up.

 

cheers
