For an inexperienced person, this would be completely unusable. I have a pretty good idea of what I’m doing and the first thing that comes up when selecting “reinstall Windows” is another window asking for the ISO and defaults to Documents. If this ISO is actually on the HD then this should at least default to where that image is. Secondly, I’d like to point out that you do actually have to have an installation image for this to work which the description hints that you don’t.
