Hi, Johan,
Thank you for the suggestion. I didn't consider that, but I should
have.
But this time I ran grub2-mkconfig, whereas I think the first time I ran
grub-mkconfig. I could not find grub-mkconfig this time, so I must have
been incorrect.
Anyway, I edited /etc/default/grub and removed the font line and added
the GFXMODE line.
I ran the command grub2-mkconfig -o grub.cfg and got the following
errors:
It returned several errors:

I'm about to reboot and see what happens. I did save a backup of the
grub.cfg just incase.
