The disk partition is a disk's logical division so that an operating system can manage data. In general, there are two partition schemes:
- Master Boot Record (MBR): This is an old partition scheme known today as a legacy boot option. It operates on a 512-byte disk sector with a maximum of four primary partitions, or three primary partitions and one extended partition. An extended partition can have up to 26 logical partitions. The MBR uses logical block addressing (LBA) to support disks up to 2 TB. The MBR, in the past and currently, has proven to be a very useful partition scheme for multiboot platforms.
- GUID Partition Table (GPT): This coexists with the MBR and is a new partition scheme that overcomes ...
