Hello Stephane:
I followed your advice, entering each of the commands into the terminal, one at a time. I have pasted the proceedings below. But then I rebooted Manjaro and there had been no change. Still the same grub menu and still running kernel 5.9.
Is there anything further I should try?
[martin@Martin-Manjaro-Desktop ~]$ pacman -Qs grub
local/grub-customizer 5.1.0-2
A graphical grub2 settings manager
local/grub-theme-manjaro 20.2-12
Manjaro Linux grub theme
local/grub-vanilla 2.04-5
GNU GRand Unified Bootloader (2)
local/python-markdown 3.3.4-1
