ShinyCuber395,

Welcome to Gentoo. On my Raspberry Pi 5, which is arm or arm64, I get.

$ emerge grub -pv

These are the packages that would be merged, in order:

You cannot choose (-plaform) settings, they are forced off.

That really leaves a choice of efi-32 or efi-64 depending on your EFI fimware.

Code: Select all

GRUB_PLATFORMS="efi-64"
