→Creation: GRUB doesn't CREATE partitions it just utilizes them for the purpose of bootloading. Adding cfdisk and fdisk as utilities that can create BIOS boot partitions.

GPTOn MBR-partitioned disks;, boot loaders are usually implemented so the portion of their code stored within the MBR, which cannot hold more than 512 bytes, operates as a first stage that serves primarily to load a more sophisticated second stage, which is, for example, capable of reading and loading an [[operating system kernel]] from a [[file system]].
