Windows introduced a new console tool called MBR2GPT, which lets you convert an MBR disk (Master Boot Record) to a GPT disk (GUID Partition Table) without data loss or modification.

MBR is an old method of partitioning disks that uses a special boot sector at the beginning of the partitioned storage to identify the location of the bootable operating system.

PCs with BIOS used to have MBR before the newer UEFI standard, which gave rise to GPT. It refers to the standard layout for partition tables using globally unique identifiers (GUIDs). But what’s the need for MBR2GPT? Let’s find out!

Earlier, users had to choose between MBR or GPT at the time offormatting the disk. That means changing the partition table style would erase data on the disk.

But with MBR2GPT released later, users can now convert an existing MBR disk to a GPT disk without deleting it. MBR2GPT.exe runs from a Windows Preinstallation Environment command prompt and a regular Windows 10 copy.

For those wondering where MBR2GPT is stored, its executable file can be found in theSystem32folder. If the file is not there,repair the corrupt system filesorperform an in-place upgrade.
