I did notice a difference between the grub process in ubuntu & fedora.. in ubuntu I remember getting a " booting in insecure mode" message BEFORE the grub menu came up. With fedora grub, that message disappeared. other differences might be so obvious..

THEN I installed a new fedora kernel, and I started the thread trying to get the new fedora kernel into the grub menu.. but first I had to either redo the ubuntu grub.cfg OR change grub to the fedora grub config.. After a few messages I got the efibootmgr -o to change the booting sequence to fedora default, that only took 2 days.. then trying to figure out the how & why of all this EFI/ubuntu/fedora/grub.cfg nonsense... > > >> > every time you boot into a specific distro, update the system, and >> > install a new kernel, well, then grub needs to be updated.
