What Is MBR And GPT?

MBR stands for Master Boot Record, whereas GPT stands for GUID Partition Table. They are two different disk types. You can convert MBR to GPT by using MBR2GPT Windows tool. This tool switches the BIOS with UEFI without deleting the data stored on the drive. And, also the current installation will not get modified.

Why Convert MBR To GPT?

Your drives wll switch from BIOS to UEFI firmware without deleting any stored data, while converting from the MBR to GPT. The GPT format is much faster than the old MBR format. That’s why, BIOS is becoming outdated and many new systems are switching to UEFI disk partitioning.

What Are Requirements Needed Before Converting MBR2GPT Tool?

The basic requirements for using MBR2GPT Tool are:

-Disk should be using MBR while converting.
-Disk partitions should be MBR types.
-The volume IDs have to be retrieved from each of the volume that has a drive letter assigned.
-Enough space to store primary and secondary GPTs in the partition.
-BCD store on the system partition has to contain a default OS entry point that points to an OS partition.
-3 partitions in the MBR partition table are allowed.
-Extended/logical partition of the disk is not allowed.
-One partition should be set as active and as the system partition.

The conversion will fail if these requirements are not met.
