How do I change my default kernel?

I’ve no idea how to mess with editing my GRUB or its config to change default + making the preferred priority as which one it’ll boot into by default.

You can set the GRUB_TOP_LEVEL variable in /etc/default/grub to achieve this, as described in this topic: New Grub option GRUB_TOP_LEVEL

@petsam

For example (as tested), you can add this line in /etc/default/grub, to set Linux main kernel at the top of the menu list:

GRUB_TOP_LEVEL="/boot/vmlinuz-linux"

Re-create grub configuration to apply the changes:

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