GPT and MBR

MBR (Master Boot Record) and GPT (GUID Partition Table) are two different partitioning schemes used for organizing data on storage devices such as hard drives. Heres a brief overview of each:

MBR (Master Boot Record)

  • MBR is an older partitioning standard that has been in use for a long time.
  • It uses a standard BIOS partition table and is associated with Legacy BIOS systems.
  • MBR has limitations such as supporting a maximum of four primary partitions or three primary partitions plus one extended partition.
  • It was the default partition table format before hard drives exceeded 2 terabytes in size.

GPT (GUID Partition Table)

  • GPT is a newer standard that is gradually replacing MBR.
  • It uses the Unified Extensible Firmware Interface (UEFI) and is associated with modern UEFI systems.
  • GPT allows for more partitions per drive and supports larger drives. It can accommodate an infinite number of partitions, making it more versatile than MBR.
  • GPT provides better data protection and recovery options compared to MBR.

In summary, MBR and GPT are different partitioning schemes with their own advantages and limitations. The choice between MBR and GPT depends on the specific requirements of the system and the hardware being used.
