Run update-grub as root to apply the changesI was trying to work through my pacnew files to merge changes and I saw one on grub that made me pause because the pacnew version didn't make a lot of sense to me.By default, Ubuntu boot loader grub doesnt use any theme. Edit, add, or remove menuentries as desired, then save the file. Alternatively, you may keep other files in the /etc/grub.d folder if you make them unexecutable. Remove all but the following files from the /etc/grub.d folder: 00header, 05debiantheme, 40custom and README.

The file on the right below is the pacnew file for /etc/default/grub, which replaces distributor of 'Garuda' with 'Arch' and seems to remove the garuda theme. Theres an open-source project maintains 4.I am using pacdiff to see the differences and trying to determine whether to replace or merge the differences. We navigate to where the grub configuration file is and the grub themes are. It takes a theme folder (or just a single picture), creates a temporary bootable image using grub2-mkrescue and launches that image in a virtual machine using KVM/QEMU, all. Then edit /etc/default/grub file, add this line:grub2-theme-preview came into life when I was looking around for available GRUB 2.x themes and wanted a way to quickly see a theme in action without rebooting real hardware.

Choose the theme, save and reboot. Start grub-customizer and choose your theme. Copy/paste the original grub.
