1. Master Boot Record

Technology & Computing · Computer Abbreviations

First sector of a disk partitioned in the legacy PC style, holding boot-loader code and a table of up to four primary partitions. It limits disks to 2 TiB and has largely given way to GPT.

Example: Windows won't install to this disk because it uses MBR and the PC boots in UEFI mode.

MBR partitioning dates to PC DOS 2.0 in 1983. Extended partitions work around the four-partition limit by nesting logical drives. Because the MBR is a single 512-byte sector, boot-sector viruses targeted it in the DOS era. Windows includes the mbr2gpt tool to convert a system disk to GPT without losing data.
