The example above is BIOS boot with a GPT labelled root disk.
Now that you've reminded me, I do have one UEFI system, and it does
contain a few extra global lines. It's also GPT labelled, and still
contains the original Lenovo Win10 installation -- I shrunk the Win10
partition and added two new partitions (Linux root, Linux
swap). Below is the grub.cfg for that machine:
IIRC, it worked fine without any of the gfx/font/video stuff, but like
you I wanted a nice big font.
Note that on this machine I just tell grub to search for the
filesystem with the label "root" instead of specifying it manually --
though it is still specified manually for the kernel argument. I don't
remember why I did that...
