I have a similar problem. The Multiboot will not work for me. I am dealing with hundres of machines but imaging has taken it's toll. The company wants to have fresh loads for each machine now. So, I've made an automated build all the way to the end. the problem is, we are trying to avoid floppies and burning a CD/DVD for each machine is out of the question. What are my other options? Can the winnt.sif be located on a USB key drive?
