|You might be able to do that. It has been done and is a MS supported way. Vista uses a PE 2.0 boot environment, then uses a special file system, sort of like a ghost image to copy over the install. By the time you played with it you would be already installed with the ISO's.|
You have to expand the vista images and either build it for your system(s) or leave all the data on and combine it to one image.
