Select the file with the image, the object in the image file, select the system disk as the destination as it is described in the Restore Data from an Image topic. Do not pay much attention to the image file, as it will be eventually discarded. The only important option at this stage is the image destination.
Is there a way to go directly to R-Drive's startup mode without having to specify what I'm trying to restore twice, and without resorting to using external media? I'm looking for a button I can press on the Action Selection screen or script I can run.
