Your trick displays them boot menu but only for 0 seconds (so you don't see it). In my opinion it's better to display it for 10 seconds. My trick displays the menu only when more options are in menu (multi boot)

Code:
 
bcdedit/deletevalue {bootmgr} displaybootmenu (so no setting at all [only show if multiple selections are in list])
