Linux - GRUB Changing Boot order

Recommended Posts

The methods for modifying your default system start have changed quite a bit over the last few years. I will add more details to this thread as I experiment, and this will be my main source, for it is written up very well and loaded with info!

- Actually, I just edited the "set default="0"" parameter to define the default option. Zero index, so count the menuentry item you want 1st, then subtract one from it and change the param.


Spoiler edition / TL;DR

    [*]open your grub.cfg, but do not edit that file
    (command) gksu leafpad /boot/grub/grub.cfg [*]search for menuentry in this listing. Find the OS choices you want. [*]open 40_custom and add the menuentry items in the sequence you wish to have your boot order
    (command) gksu leafpad /etc/grub.d/40_custom [*]After pasting in the proper and desired 'menuentry' items, save the file. [*]Backup grub.cfg to a sub-folder and remove it from /boot/grub/ folder. [*]Also backup into a sub-folder 30_os-prober & 10_linux (then remove from main folder) which can be found in: /etc/grub.d/ [*](command) update-grub [*]Reboot and see if it worked

gksu may be redundant as root, but it is a good practice to be in, for other distros as a regular user level account.


The guide also covers custom splash screens and stuff. Fun, but I have some other things to finish up on first :)
