"Imagine a scenario where the 14_menu_show_once script does not properly revert to normal behavior after being triggered. What troubleshooting steps would you take to diagnose and resolve issues related to the persistent visibility of the boot menu?"
I'll firstly check the scripting issues whether the menu_show_once_timeout variable is set or not and also setting the timeout value, ensuring the menu is visible for a certain timeperiod.
If the issue, still persists we can check the script on a different system, if it works there, a hardware problem could also be there.
Though the script "14_menu_show_once" has its own functionalities which enables debugging in exceptional boot scenarios like this.
