I can't figure out why the command sudo update-grub does not update my menu. The system is UEFI. The menu is never changed. This used to work fine until I booted into Ubuntu (sd5). I am thinking it did something and changed the menu to its own grub but can't fix it to use my own from Kubuntu on sd6.

Here is the command output:

~$ sudo update-grub

    You have two menu systems, UEFI & grub. The sudo update-grub only updates grub menu, but not UEFI settings. And all Ubuntu, official flavors of Ubuntu and some non-official flavors use "ubuntu" entry in UEFI. Then grub menu has the other installs. So what menu do you want to update? It looks like grub has multiple installs? – oldfred Dec 10 '20 at 3:32
  • The Ubuntu UEFI as in the grub menu image above, What are the steps? Can't I use Grub Config? -Thanks – user603749 Dec 10 '20 at 22:20

    You show multiple Linux installs. So are you updating one install, but default boot is really a different install? You have multiple grub installs, one per system, but only one is controlling boot. The grub that controls boot should be the system you use as your primary system. – oldfred Dec 11 '20 at 4:36
