Found out that it was installing the Intel graphics drivers while the system came with the nVidia Quadro card (system can come with either of them). I had already manually set the nvidia in HII so I set the Intel detection to the nVidia Quadro driver also. System imaged successfully.
I found this by just watching the HII step and seeing if any drivers failed. Sure enough the intel graphics driver was failing which the device has the nVideo graphics card.
Thanks for your help Kevin!
