Line 3: The '''BIOS boot partition''' is a [[partition (computing)\|partition]] on a [[data storage device]] that [[GNU GRUB]] uses on legacy [[BIOS]]-based [[personal computer]]s in order to [[Booting\|boot]] an [[operating system]], when the actual [[boot device]] contains a [[GUID Partition Table]] (GPT). Such a layout is sometimes referred to as BIOS-GPT boot. A BIOS boot partition is needed because GPT uses the [[disk sector]]s immediately following the [[Master Boot Record]] (MBR) to hold the actual partition table, whereas the traditional MBR-based partitioning scheme does not designate them for any special purpose. As a result, there is not enough unused space available for storing second stages of [[boot loader]]s on GPT disks; boot loaders are usually implemented so 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 ~~complicated~~sophisticated second stage, which is, for example, capable of reading and loading an [[operating system kernel]] from a [[file system]]. == Overview ==
