I've had that experience if I had nothing specified as
boot source.
However, when I specify the wrong name, then I end up
in Rommon.
I'm speaking from the top of my head, but that's what
I think happens every single time.
I have not systematically validated it though. Might
be an interesting exercise - just so it never comes up
again in any way ambiguous.
However, I'm pretty sure my results are the same every
time.
