Sysprep is killing me

So… I’m, now for the fourth time, trying to make an image of a laptop here. Every time so far, when I use sysprep then i create the image, after I restart the computer, I get an error that ways “The system is not fully installed. Please run setup again.” I have no idea what the problem is because I have used Sysprep many times, and this is the only computer that it seems to be happening on.

PLEASE HELP!!! (I really need to get the boss off my back…)
