We have a modified ISO of Windows 7, used to deploy a customized Windows 7 Enterprise operating system. We have a number of Toughbooks that need the operating system installed. We can currently install it using a DVD. I'd like to install it using a switch we have, using one of the laptops we have to automate the install process to the other laptops. I've tried Serva, but because of the modified structure of the ISO, it will not work. I've tried using WAIK and MDT to assist, but I've yet to find a way to due it. Another way I've seen is using the current install of the OS on an updated toughbook to create a VHD, and use WinPE to make the VHD bootable once its been copied to the other computers. Would this way be quicker and more efficient?
