Open a terminal window, then back up the existing grub config file:

sudo cp /etc/default/grub /etc/default/grub-backup

Now (using sudo or gksudo depending on your editor of choice) edit /etc/default/grub and change the number in this line of the file


to your desired waiting time in seconds.

Exit, saving the file, and then run

sudo update-grub

On your next boot you should have the wait time you specified.

  • Creating a backup of grub file is a very good idea to recover from a messed up situation. Btw, I required root privileges to edit the grub file else it was giving access denied error as mentioned here – RBT Dec 6 '17 at 0:02
