2 Ways to Convert MBR to GPT

In this blog, we will discuss what is MBR and GPT and how to convert MBR to GPT.

What is MBR (Master Boot Record)?

Master Boot Record is a special record in hard disk via help Operating System boot-up. If you purchase a new Computer or Laptop then MBR record all the information about which location Operating System will be boot-up.

Master Boot Record (MBR) was Developed by IBM with Dos 2.0 in 1983. Master Boot Record is a special boot sector located at beginning of the Hard Disk and also the First Sector of the drive.

Master Boot contains a Bootloader for installed Operating Systems. The bootloader also provides information about logical Drives like C, D, E, etc. Each and Every Drive have separate boot loader information.

All the information about the Operating System Boot Loader is available in the Boot Loader Sections of MBR. Master Boot Record become the Industry Standard used for partitioning and booting from Disks.

What is GPT (GUID Partition Table)?

GPT (GUID Partition Table) is the latest technique to partition of Hard drive with UEFI (Unified Extensible Firmware Interface) firmware. UEFI is the replacement of BIOS (Basic Input Output Systems).

GPT provides a Globally Unique Identifier (GUID) address to the hard drive.GPT is a new standard for the partition of Hard drives that are gradually replaced with MBR because MBR supports a maximum of Partitions of up to 2TB whereas GPT supports a maximum of up to 18 Exabytes.

You need Windows Vista 64 bits or the latest version of the Operating system and an UEFI-based Computer that can be booted from GPT Partition. If you want to read GPT partitions you need the minimum required Windows XP 64 bits Operating System.

Why Should We Convert MBR to GPT?

GPT is the latest Partition type of Hard Disk that replaces MBR associated with UEFI. GPT will provide the largest size of Hard drive partitions that depend on its operating system and File Systems.

In GPT Partition you do not need to create extended partitions because GPT allows 128 partitions on a GPT drive.

The main advantage to convert MBR to GPT because rarely chances of data loss because GPT stores multiple copies of data across the Disk. If any time data is corrupted can be easily recovered.

Note- Before converting your Drive MBR to GPT you should take a backup of the Hard Drive because erase all the data from Drive.
