Add Power Off and Reboot to grub menu

To add Power Off and Reboot options to grub menu, you need to update a file in your grub configuration directory.

cd /etc/grub.d



Open 40_custom in your favorite editor

For me its micro :

micro 40_custom



Add following line at the end of the file


 menuentry "Reboot" 
      reboot


menuentry "Power Off" 
      halt


Do not change the exec tail line in the file



Update your grub.cfg file

  • For Debian based distros
update-grub
  • For Arch based and Other distros
grub-mkconfig -o /boot/grub/grub.cfg
