How to Convert MBR to GPT Without Data Loss

While MBR has been a standard partition style for a long time, GPT is becoming increasingly popular among users and professionals. Therefore, more and more users want to learn how to convert MBR to GPT without losing data.

How to convert MBR to GPT

Fortunately, there are multiple ways to convert to GPT without data loss. In our guide, we aim to cover the difference between MBR and GPT, their pros and cons, how to determine which system you are using, and how to change MBR to GPT without losing data.

Why Should You Convert Disk to GPT Without Losing Data?

Before using the disk, it must be partitioned. MBR and GPT are two different ways of storing information about disk partitions.

A master boot record (MBR) is a special type of boot sector at the very beginning of partitioned computer mass storage devices like fixed disks or removable drives intended for use with IBM PC-compatible systems and beyond.

GUID Partition Table (GPT) is a standard for the layout of the partition table on a physical storage device used in a desktop or server PC, such as a hard disk drive or solid-state drive, using globally unique identifiers (GUID).

MBR has certain limitations that can be felt by the users of drives with large capacity. Namely, MBR supports only 4 primary partitions, each with a limit of up to 2 TB. GPT has increased these limits drastically, supporting up to 128 primary partitions, each with a capacity of up to 9.4 ZB (or 9.4 billion TB).

While MBR to GPT conversion is obviously beneficial, there are certain risks related to the process. If done wrong or interrupted, it can cause data loss and memory damage. You might restore the information using a formatted partition recovery tool, but hardware issues cannot be solved that easily. So, you need to know how to convert from MBR to GPT without losing data.

First, let’s look at two ways to check which partition table your disk uses.

Using the Disk Management tool

Step 1. Right-click on the Start menu or use the keyboard shortcut “Windows + X” on the keyboard and scroll down the menu.

Step 2. Click on “Disk Management”.

Step 3. Find the disk that you want to check. Right-click on it and select “Properties”.

Step 4. Click the “Volumes” tab. In the “Partition Style” line, you will see either “Master Boot Record (MBR)” or “GUID Partition Table (GPT)”.

Using Diskpart

Use the “diskpart” command in the Command Prompt window. Run the command prompt as administrator by clicking the Start button with the right mouse button or by pressing Windows + X shortcut and selecting “Command Prompt (Administrator)”.

You will see a table with a list of connected disks. If the disc uses GPT, the “*” symbol will appear in the column “GPT”. If the MBR standard is selected, the GPT column will be empty.

Now you can create partitions using the disk management window and transfer your data to new partitions.

How to convert MBR to GPT without losing data?

How to convert to GPT without losing data in Windows 10? There are several methods for converting MBR to GPT.

How to convert MBR to GPT without losing data in Windows 10

Method 1. Command prompt

You can convert MBR to GPT without data loss using a command prompt, namely the Diskpart command. Here’s how to convert MBR to GPT without losing data using cmd:

1. Press the Win + R shortcut on your keyboard to open a command prompt and start it as an administrator. Type in “diskpart” and press Enter. Then the command prompt window will appear. If the disk does not contain partitions or volumes, go to step 5.

2. Enter “list disk” and press “Enter”. Record the number of the disc that you want to convert.

3. Enter “select drive” and press “Enter”.

4. Type “clean” and press Enter to delete all partitions or volumes on the disk.

5. Click “convert gpt” and click “Enter”.

6. Type “exit” and press Enter to exit cmd.

You can switch from MBR to GPT using the Diskpart command

Method 2. Disk Management

Disk Management is a built-in tool for Windows 10. It allows you to manage partitions of the hard disk without rebooting the system, convert them to MBR or GPT.

1. Click “This Computer” → “Management” → “Disk Management”.

2. Right-click on the disk that you want to convert. You will see the inactive function “Convert to GPT disk”.

Note: If your MBR hard drive has a partition or volume that you can convert, right-click any volume on the disk, and then click “Delete Partition” or “Delete Volume”.

Disk Management allows you to manage partitions of the hard disk without rebooting the system

Method 3. Convert MBR to GPT without losing data using Gptgen

Gptgen is a nondestructive command-prompt utility that can convert partitions of a hard disk, meaning that this is another way to convert MBR to GPT without data loss using cmd. To convert MBR to GPT without data loss using Gptgen take these steps:

1. Press Win + R to open the command prompt and start it as an administrator.

2. In the command prompt window, type the Gptgen command:

gptgen.exe \\. \\ physicaldrive1

You can convert MBR to GPT without losing data using Gptgen

Then you will see two files: primary.img and secondary.img. They contain data that will be written to disk.

3. To change the partition, just type the following in the command line:

gptgen.exe -w \\. \\physicaldrive1

You can use command prompt to change the partition

Now you know how to use Gptgen and can successfully convert MBR to GPT.

Method 4: Change MBR to GPT without losing data using MBR2GPT

MBR2GPT is another command-prompt tool available in Windows 10. It can simply be launched from the Advanced Recovery Command Prompt through the Windows Preinstallation Environment (WinPE). The method is rather complicated, so you can get more detailed information on Microsoft’s website.

Changing MBR to GPT using MBR2GPT

With the above methods, you can easily convert MBR to GPT in Windows 10 without losing data.

As you can see, all methods of conversion are applicable in Windows 10. These methods successfully convert MBR to GPT without any data loss.

Recovering information after unsuccessful MBR-GPT-MBR conversion

If you’ve managed to successfully convert MBR to GPT cmd without data loss, congratulations! However, there are dozens of other ways your files might get lost, corrupted, or destroyed. This is where data recovery software from East Imperial Soft might help you.

If you’ve encountered some issues while trying to convert a disk to GPT without losing data, use the Magic Partition Recovery software to restore your partitions to a fully working state. Use the data recovery pack for any other data you need to restore.
