The steps to tie a bow tie are the same as those used to ties one's shoelaces-assuming that the wearer does not tie his shoes with a granny knot.
I agree that guides are not very helpful. I would suggest that the frustrated novitiate go to a reputable men's store and ask a salesman to show you how. Stay until you get it right. In my years as a "counter-hopper" in a fine old men's store, I gave many lessons in how to tie a bow tie.
