Q2: Can Images be deployed that I did not capture?
The short answer is No. You must capture the image from FOG to deploy it.
There is no central repository for OS images. You must create your own, based on your own requirements from DVD. In my company’s case we use MDT to build our golden image then capture and deploy with FOG. A hardware agnostic design is surely possible. We have a single image that we deploy to 15 different models in our fleet of computers. The key/trick is to use a FOG post install script to copy the correct drivers to a defined location on the target computer just after deployment, but before the first OS boot. Once the drivers are at the precise location then windows will detect them and load them. Sometimes we find that we need to use dism in the the setupcomplete.cmd to finish injecting the drivers after oobe but before first login. It does take time to setup your environment but once done you can regenerate your golden image at any time with the latest windows updates if you use MDT.
