MBR and GPT Partition
A partition is a virtual division of a hard disk drive (HDD) or solid state drive (SSD). Each
partition can vary in size and typically serves a different function. Before a drive can be
divided into individual partitions, it needs to be configured to use a specific partition scheme
or table.A partition table tells the operating system how the partitions and data on the drive
are organized.
There are two main types of partition tables: MBR and GPT.
MBR stands for Master Boot Record, and is a bit of reserved space at the beginning of the
drive that contains the information about how the partitions are organized. The MBR also
contains code to launch the operating system, and it's sometimes called the Boot Loader.
GPT is an abbreviation of GUID Partition Table, and is a newer standard that's slowly
replacing MBR.Unlike an MBR partition table, GPT stores the data about how all the
partitions are organized and how to boot the OS throughout the drive. That way if one
partition is erased or corrupted, it's still possible to boot and recover some of the data.
Differences between MBR and GPT Partition
Characteristics
MBR GPT
Definition
MBR (Master Boot Record) is a
type of partition used to set up a
hard disc.
GPT is crucial to comprehend
whether to construct a new
division or convert an old one.
Compatibility
MBR is the most common format
and is compatible with BIOS
systems.
GPT is a newer type that works
with UEFI systems.
Limitation
MBR may accommodate up to
four primary or three primary
partitions plus one extended
partition.
GPT can accommodate an
infinite number of partitions.
System types If the system is BIOS, we can use
Master Board Record.
If the system is UEFI, we can
use either MBR or GPT.
Complexity
MBR is less complex than GPT GPT is also more complex than
MBR and works with all
operating systems.
