But GRUB supports only 256 color JPG/JPEG image formats only. You can use JPG/JPEG format images as well. To change the GRUB background image, you need to copy your preferred image to /boot/grub/ location. If you set it as " 1", the second OS will boot, and so on. If you set the value as " 0", the first operating system in the GRUB boot menu entry will boot. We can select the default OS to boot using this option. $ sudo nano /etc/default/grubįind the line " GRUB_DEFAULT".

Sample output: # If you change this file, run 'update-grub' afterwards to update The contents of typical grub file will look like below. $ sudo cp /etc/default/grub /etc/default/grub.bak Any changes you made in in /etc/default/grub file will be reflected to the GRUB2.įirst, backup the /etc/default/grub file before making any changes. The /boot/grub/grub.cfg file is automatically generated by grub-mkconfig using templates from /etc/grub.d and settings from /etc/default/grub. Any misconfiguration in this file may lead you to end up with broken Ubuntu system. This is the main file to boot into the Linux OS. You shouldn't edit or modify this file, unless you are much familiar with GRUB2. Warning: The default configuration file for GRUB2 is /boot/grub/grub.cfg. Like I already said we can configure boot loader settings from command line or GUI.
