Normally, I would agree but the 7 PC is headless/keyboardless part of a larger system that is controlled by pilots who don't always wait and weight is an issue. Basically, I'm capturing video/pictures on an aircraft and need to keep things as simple as possible and, more importantly, save the data. Right now, I have AutoHotkey run on start-up and gets everything going. I'm writing another script right now to shut the system down using a keyboard command but would like to find a way to do this as a "in case" condition.
Does booting from an on board ISO image allow writing to an attached drive(non-os)? If so, I may go that route.
This system is definitely not the best solution in this case but some requirements drove me too it.
