Just like MBR, it also manages the creation and organization of partitions on the HDD. Next, the MBR activates the boot sector of the drive to launch the OS.

The PC’s/motherboard’s basic input/output system (BIOS) looks for the device with an MBR, and then it executes the volume boot code from the partition that has it. This identifier ensures that the correct drive and partition reads and writes data when using several disks, and it ensures proper PC functionality and security protocol for all read/write data transactions.

Disk signature: Every drive needs a unique identifier, which gets created in the form of a signature.

Master boot code: Sometimes abbreviated as MBC, the code executes the launch of the operating system and manages the configuration for the bootup process (to confirm any changes), such as detecting drives, calculating RAM (external), detecting displays, and other essential device and configuration information.

The MPT provides all that essential information. For the OS and the PC to function correctly, they need a record of HDD partitions and sizes and a way to identify the bootable, active partitions.

Master partition table: Abbreviated as MPT, the table stores all partition information found on each HDD, including their format type, capacity, and other necessary details.

The MBR data stored in LBA 1 of the HDD includes the following: The data includes information related to how and where Windows resides to manage the boot process in the PC’s primary storage and internal random access memory (RAM), not external memory such as DDR2 and DDR3 memory cards/sticks. MBR uses Bios firmware and stores code in the disk’s first sector with a logical block address (LBA) of 1. MBR manages how partitions are created and organized on the hard disk drive (HDD).

Another reason to use partitions is to install multiple operating systems on the same HDD (Linux, Windows10, Windows 7, etc.) What is MBR? Windows displays them as drives in File Explorer, even though they are on the same hard disk drive (HDD).įor instance, many laptops have a “system” partition where everything in the Windows Operating System (OS) goes (often the C: drive), plus a hidden “recovery” partition that can get used to restore the system in case of an accident. Partitions are separate sections on a hard drive that the operating system uses to boot and function. To understand both MBR and GPT, you should understand what a partition is. This article explains what they are, what they require, and how they differ.
