Morning Vic - can't see any way around the problem when loading the system.
I had a Google search and the Microsoft site seems to be the best way at finding a solution.
Once upon a time I would attempt to recreate a problem as I found it was the best way to learn how to get out of it. These days I wouldn't dare as the operating systems etc. have changed so much and the new terminology (even though it is just replacing terms we used to use) is confusing.
This is the address of the Microsoft site, that you may already have looked at :-
