Yeah, the problem is that always adding the Boot Menu to the top of BootOrder 
causes confusion to the users who manipulate the Boot Order under OS. Also, we 
can't find any reason why the Boot Menu needs to be always added to the top of 
the Boot Order even if we check the change history and emails.

Subject: [PATCH v2] MdeModulePkg/UefiBootManagerLib: Put BootMenu at the end of 
BootOrder

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=3135

When Boot Menu does not exist in the BootOrder, BmRegisterBootManagerMenu will 
create one into list. However, it should be put at the "end" of BootOrder 
instead of "start" of BootOrder. Replace 0 by -1 to adjust order of load 
options.
