The most common partitioning scheme for x86 and x86-64 computers is MBR(Master Boot Record). This method stores its data in the first sector of the disk, called the Master Boot Record. Assuming 512-byte sectors, MBR partitions can’t support disks larger than 2 TB.

MBR supports three types of partitions:The lady in white colin campbell.

• primary – the simplest type of partition. A disk can have zero to four primary partitions, one of which may be an extended partition.
• extended – a special type of primary partition that serves as a placeholder for logical partitions. A disk may have at most one extended partition.
• logical – partitions that reside within an extended partition.

Primary partitions are numbered from 1–4, whereas logical partitions are numbered 5 and up.
