2 Ways to Clone MBR to GPT in Windows 11/10/8/7

Emmanuel | Apr 24,2022 9 min read

The GPT was presented as a part of the Unified Extensible Firmware Interface (UEFI). GPT gives a more significant number of options than the conventional MBR partitioning method typical in Windows 11/10/8/7 PCs.

If you have a big-sized Hard Drive, you may be considering converting MBR to GPT. This is because MBR disks support just four partitions. Assuming you need more partitions, one requirement is to create an optional structure known as an extended partition.

Also, Windows has enacted stringent requirements to be met before installing Windows 11. So, to get the improved security features of UEFI, Windows 11 will do without the older Master Boot Record (MBR) partition and, in its place, utilize the modern GUID partition Table (GPT) scheme. If your PC is still using MBR, you need to convert it to GPT before updating to Windows 11.

This guide will examine two effective ways to clone MBR to GPT in Windows 11, 10, 8, and 7.

What are MBR and GPT?

What is MBR?

MBR is an acronym for Master Boot Record and was the original partition table format before hard drives became larger than 2 TB. MBR controls how partitions are designed and organized on the hard disk drive. The MBR is older than the GPT, making it more compatible with some older versions of the Windows system.

The total hard drive size of MBR is 2 TB, and it uses BIOS firmware and codes in the drive's first sector. So if you have a hard drive of 3 TB and your system is using MBR, only 2 TB of the 3 TB hard drive partitions will be accessible. If you have a hard drive with 2 TB or lower, MBR should be selected when initializing the hard drive for the first time.

What is GPT?

GPT is the short form for a GUID Partition Table. Like MBT, it manages the creation and arrangements of partitions on the hard disk drive. Unlike the MBR, GPT utilizes the UEFI firmware and keeps disk information, such as partitions, sizes, and other vital data.

GBT uses two sectors, and one sector is kept for MBR and BIOS compatibility. The GPT has a maximum hard drive size of 9,400,000,000 TB with sector sizes of 512 (standard size for modern hard drives).

You can boost your system using GPT if you have a hard drive larger than 2 TB. However, you need a supporting operating system and UEFI system software.

The Preparations You Need to Do Before Cloning

Before cloning MBR to GPT, there are some basic requirements to ensure smooth conversion without data loss. The preparations needed include:

  • Get a new hard drive with larger disk space.
  • Back up all critical data on your hard drive to prevent data loss.
  • Make sure the hard drive is in GPT format.
  • If it's a new drive, connect to your PC and open Disk Management to initialize it with the GPT partition style and add volumes to the hard drive.

  • For a hard drive previously initialized with MBR, open Disk Management and delete all the volumes in the hard drive. This prepares the disk partition for easy conversion to GPT.
