Make GRUB (GRUB2) Remember Last Choice on Linux

Having multiple boot options managed by a boot manager like GRUB is a common thing on Linux or a Windows dual-boot machine, but to select the os/kernel in a 5 seconds window is a pain in the ass. So how about making GRUB remember your last boot choice?

Backup GRUB

First, backup your current GRUB configuration /etc/default/grub to /etc/default/grub.backup, in case anything goes wrong:

$ sudo cp /etc/default/grub /etc/default/grub.backup


Open the GRUB configuration /etc/default/grub with the text editor of your choice:

  • vim (command-line editor for advanced user)

    $ sudo vim /etc/default/grub
  • nano (easy to use command-line editor)

    $ sudo nano /etc/default/grub
  • gedit (editor with graphical interface, default text editor of Ubuntu and distros with GNOME)

    $ sudo gedit /etc/default/grub


    $ gedit admin:/etc/default/grub
    /etc/default/grub opened with gedit

Add or edit the parameters GRUB_DEFAULT and GRUB_SAVEDEFAULT:

Plain text

Make GRUB Configuration

Generate GRUB configuration:

  • Debian/Ubuntu-based Linux

    $ sudo update-grub
  • Arch Linux/Manjaro

    $ sudo grub-mkconfig -o /boot/grub/grub.cfg
  • RHEL/CentOS/Fedora

    $ sudo grub2-mkconfig -o /boot/grub2/grub.cfg

Now, the selected boot option will be remembered for the next boot up.
