Maybe I'm just romanticizing the past, but the biggest problem with EFI Boot, whether Grub2, elilo, or rEFInd IMHO is understanding what each bootloader can see and what graphics options are possible for us to see. It has definitely irked me plenty when either of those bootloaders fails to find a kernel or ignores or ruins a graphics option. LILO was just simpler and more direct and well documented as to what resolutions were possible.

All I expect from a bootloader is to boot and display the text of the process in a resolution that suits my graphics systems and my eyes. Grub2 is like a mini (and rather arcane) OpSys.

What's interesting about this post is when I originally made it the problem only existed with my Nvidia GTX 970. I had to add the "GRUB_PRELOAD_MODULES=all_video" to the grub default to get a high resolution console. Once I was able to finally buy my RTX 3060ti I no longer had add the preload modules for it to work. And none of my other machines with AMD and intel cards required it either

I have an RTX 2070 which did require it, go figure.
