Another thing you could consider, is to let the repair shop fix what is wrong with the computer (I'm assuming it is something physical). Then put the sytsem image, which you made of it earlier, on it. You may find everything is good. If the computer problem was physical, then your image won't break anything (unless in the unlikely event you have a really nasty virus that actually attacks the computer physically. Which the repair shop should catch). But even if the image doesn't work out, you can simply delete the partition and start over, following suggestions already made in this thread (calling Microsoft, using alternative activation methods, etc.).
