Receive No valid source drive when trying to image a Toshiba M400 tablet

I have 40 Toshiba tablets to try and create an image for to facilitate a launch of a new third party software which will require a full drive reimage. When I run Ghost Boot disk against the Toshiba M400 tablet to create the image I receive an Error " There is no valid Source Drive to choose (11032)."  Is there a solution out there.
