Bootloader

As of Mint 19.2 the default bootloader is Grub2 or specifically grub-install (GRUB) 2.02-2ubuntu8.13

You may find that you want to change the order of the operating system options or set a default boot option.

technical point: GRUB 2 works like this: /etc/default/grub contains customization; /etc/grub.d/ scripts contain GRUB menu information and operating system boot scripts. When the update-grub command is run, it reads the contents of the grub file and the grub.d scripts and creates the grub.cfg file.

The problem is that mint is lazy using an os prober script that grub reads each time and it creates the boot order. It is a pain to deal with this because you would have to manually create a script for each os in /etc/grub.d since none exists other than it relying on os-prober, therefore it is easier to go the GUI route.
