The easiest method would be to chroot into your installation. From there, you can format the EFI partition, then mount it. If you don't have mkfs.vfat in your chroot, I think the package that has it is dosfstools. So basically: 1. chroot into your install (makes sure /boot is mounted before chroot'ing in) 2. format the EFI partition, install dosfstools if required 3. mount the EFI partition to /boot/efi 4. grub2-install --target=x86_64-efi The grub.cfg you showed before looked correct to me, the Gentoo GNU/Linux entry was trying to boot off of root='hd0,gpt2' which is correct.
