Good assumption Lonnie; you were correct. I tried those shortcuts and  
they did work. This does appear to be the way that FC is handling  
things.

Excellent suggestion. I had not thought of that. I just made the  
change. This will solve all of the booting issues.

It never actually booted from the external; just tried to. There is  
nothing on the external that it could use to boot.

The frustrating thing is that the/an external drive is not listed as  
an option in the BIO boot order. And, even if it was, the option to  
disable items does not exist; you can only change their priority.  
Very frustrating.
