the standard way was to make partition #4 of type 'logical' which is a container where you can add several more partitions, like separate linux /home (recommended) and linux swap. also, if necessary, grub could even boot a logical partition too.
i dunno about efi but for sure grub can boot a lot of things in different ways. it also has an efi emulation module.

guess that should have been 'GRUB-pc' here
