grub2 - Can I set Grub to not boot a default OS?



I'd like the computer to wait at the Grub screen for me to make a choice, rather than picking one option and running with it. Is there a way to have no default operating system in Grub?



You can set GRUB_TIMEOUT to a very big value or to -1 (infinite). This is by default set at 10 seconds. To change it, edit /etc/default/grub file using the following command in terminal:




gksu gedit /etc/default/grub


After you finished to edit that file, save it and don't forget to update your Grub using the following command:



sudo update-grub
