Recommended way to switch which kernel is booted with grub

When I installed EOS Plasma I checked the box to also install the LTS kernel, so in grub that is the one that is booted. I’d like to make the normal kernel be the default with the LTS kernel be for backup if there is an issue with booting.

I also have grub-btrfs installed so EOS Snapshots are also a boot choice.

I’d like to make this change without messing something up that will get overwritten when grub is updated.

Ideas?

I followed this before to set the latest kernel as default and LTS as second option in Grub menu.

GRUB_TOP_LEVEL="/boot/vmlinuz-linux"

What about Arch Linux Kernel Manager?

That works fine. I didn’t change anything else in /etc/default/grub; I just added that one line.

That one line is enough. I am glad that it worked for you.
