Ctrl + Alt doesn't work?

[rhuhman]

I have been getting a few laptops that no matter when you press the Ctrl + Alt key's to get into ZENworks Imaging the laptop fails to notice the key prompts. It passes the prompt like the keys aren't pressed. I can place a new hard drive in the laptop or clean the drive and it will then work correctly. Does anyone know how I can get this to work again? I updated a new Image for the laptops we have and would like to upload that image but the laptop will not boot into ZENimage.

Thanks
