Should I Use MBR or GPT

As Windows partition styles, both MBR (Master Boot Record) and GPT (GUID Partition Table) are widely used in storage devices like your computer hard drives. But nowadays, more and more users are changing their disks from MBR to GPT. Why?

MBR vs. GPT

Here is a comparison table of MBR vs. GPT, from which you will learn which partition style you should use for your disk:

Which Is Better? Advantages of GPT Disk over MBR Disk

According to the comparison table, it's clear that the advantages of GPT disk exceed MBR disk, which is especially obvious in the following aspects:

• Faster Boot Speed: GPT UEFI can load the operating system faster than traditional MBR BIOS boot mode.
• Better Operating System Compatibility: GPT has better OS compatibility than MBR as it supports most operating systems, including Windows Server and macOS.
• Advanced Data Protection: GPT contains the backup of the primary GPT header and partition entries that protects data on the disk better.

When Do You Need to Convert MBR to GPT

Based on the above information about GPT disk, you may have learned the GPT exceeds MBR in many aspects. However, some users are not quite clear about when they need to convert MBR disk to GPT disk.

Method 2. Change MBR to GPT via Disk Management

Both Disk Management and DiskPart commands require you to delete all partitions on your disk. Thus, if there are useful files on the disk, back them up in advance. If there are lots of files on your disk, you can use the free backup software - EaseUS Todo Backup to make a backup of your files, which is much faster and effective than manually copying and pasting. To change an MBR disk to GPT in Disk Management:

Step 1. Righ-click on 'This PC (in Windows 10)' and choose 'Manage'.

Step 2. Select 'Disk Management', right-click each partition on the disk you want to convert and choose 'Delete Volume'.

Step 3. After deleting all the volumes on your disk, right-click your MBR hard drive and choose 'Convert to GPT Disk'.

Close Disk Management when the conversion process accomplishes. You may use your new disk to create as many partitions as you want or install a new OS on the disk now.

Note: If you didn't delete all the partitions on the MBR disk, the 'Convert to GPT Disk' option will be greyed out in Disk Management. You will see it choosable after removing the existing partitions.

Method 3. Convert MBR to GPT using DiskPart

Back up your disk and then follow the steps below to convert your MBR disk to GPT.

Step 1. Click the 'Start' button and type cmd.

Step 2. Right-click 'Command Prompt' and choose 'Run as administrator'.

Step 3. Type diskpart and hit Enter.

Tip: If you forgot to back up files and want to undo the clean command, you can use EaseUS partition recovery software to retrieve your partitions and files.

Bonus Tip: How to Convert MBR to GPT without Operating System

Besides converting data disk or system disk to GPT, some people may also want to know how to convert MBR disk to GPT without operating system or during Windows installation.

To convert MBR to GPT without OS is more complicated than the above case. For a manual resolution, you will need to boot the computer from the Windows installation CD, DVD or media and then apply CMD command to convert disk.

However, it's too complex for most ordinary people. To save your energy and offer you a reliable & efficient solution, we would like to recommend you try EaseUS Partition Master via a USB bootable disk.

As there is no operating system, you need to install this software to another healthy computer to create a bootable disk on a USB drive and then convert MBR to GPT without operating system or during Windows installation on your own with the following steps:

Step 1. Prepare a disc or drive.To create a bootable disk of EaseUS Partition Master, you should prepare a storage media, like a USB drive, flash drive, or a CD/DVD disc. Correctly connect the drive to another bootable computer. Then, launch EaseUS Partition Master, go to the 'WinPE Creator' feature on the top. Click on it.

Read on and check the answer to your question here now:

1. Is GPT or MBR better?

Generally, GPT is better if your hard disk is larger than 2TB. As you can only use 2TB of space from a hard drive which is of MBR style.

Also, if you intend to create more than 4 partitions, GPT is better. GPT disk supports a maximum of 128 partitions and the MBR only supports up to 4 partitions.

If you need to install the latest operating system on your disk with a fast boot speed, GPT is better. GPT supports UEFI boot mode which loads the operating system faster than the traditional BIOS mode on MBR disk.

2. Should I use MBR or GPT for SSD?

According to the MBR vs. GPT comparison table at the beginning of this page, we have reasons to believe that GPT is more suitable for an SSD disk.

GPT supports more than four primary partitions on SSD. It supports more than 2TB storage (compare to MBR). Also, it is more compatible with the newer UEFI-based systems.

3. Will Converting to GPT delete data?

Windows Disk Management can change MBR to GPT disk for free, but it only supports to convert a non-partitioned hard disk. That is to say, you must delete all your partitions on the disk before the converting process, which will result in data loss.

Fortunately, you have a second choice that you can apply EaseUS Partition Master to convert MBR to GPT without data loss. You may revert back to Method 1 on this page for a detailed guide.
