Normally you'd just hit and hold the SHIFT key at boot time (immediately after the BIOS POST screen) to display the GRUB menu, but if you want it displayed at EVERY boot without user intervention ..
OK, to display the GRUB menu at every boot .. run:
sudo gedit /etc/default/grub
Find the line that reads:-
GRUB_HIDDEN_TIMEOUT=0and comment it out .. so it now reads:-
# GRUB_HIDDEN_TI MEOUT=0SAVE the file, and run:
The above edit to /etc/default/grub will have made the GRUB menu display at each boot .. BUT .. the countdown timer to booting the default OS will still be governed by the line:-
GRUB_TIMEOUT=10If you want to stop the countdown timer completely .. change that lines value to "-1" .. so it now reads:-
GRUB_TIMEOUT=-1SAVE the file, and run:
--
