How to show always the Grub menu

If we want to see the Grub menu every time our machine boots, edit its configuration file.

$ nano /etc/default/grub

and set:

so that Grub shows a countdown to the automatic boot. Press Shift during the countdown to make the menu appear.


(nothing after the equal sign) to always display the menu.


(number of seconds before the automatic boot) The value -1 means that there will be no automatic boot.

Note that spaces are not allowed on either side of the equal sign.

You need to upgrade grub for the settings to take effect:

$ sudo update-grub
