How to Convert MBR to GPT Without Data Loss

If you’re looking to convert your MBR to GPT without losing any data, you’ve come to the right place. In this blog post, we’ll show you how to do just that in a few simple steps.

How to Convert MBR to GPT Without Data Loss

What is MBR?

MBR is short for Master Boot Record and is a key part of how a computer starts up and boots. The MBR is typically located on the first sector of a hard drive and contains boot information and the location of the computer’s primary partition table. When a computer is turned on, the BIOS first loads and executes the bootstrap code from the MBR, which then loads the operating system from the primary partition.

GPT is short for GUID Partition Table and is a newer standard that is slowly replacing MBR. GPT uses a different partitioning scheme and is more flexible than MBR. It also supports larger partitions and uses a different boot mechanism.

converting from MBR to GPT is a fairly simple process and can be done without losing any data.

What is GPT?

GPT is a standard for partitioning disks that is becoming increasingly popular, especially among users of large disks. GPT is short for GUID Partition Table, and it is an extension of the traditional MBR (Master Boot Record) partitioning scheme.

GPT disks use a GUID (Globally Unique IDentifier) to identify each partition on the disk, rather than the older and now more limited MBR approach of using just a number to identify each partition. This GUID is stored in both the partition table and the boot sector of the disk, which helps to ensure that the data on the disk is correctly identified and located.

GPT disks also use a more robust and reliable form of CRC (Cyclic Redundancy Check) to verify the integrity of the data on the disk. This means that GPT disks are less likely to experience data corruption than MBR disks.

Finally, GPT disks allow for a much larger number of partitions than MBR disks. MBR disks are limited to a maximum of four primary partitions, or three primary partitions and one extended partition. GPT disks can have an unlimited number of partitions.

While GPT disks have many advantages over MBR disks, there are a few situations in which you might need to convert a GPT disk to MBR. For example, some older operating systems cannot boot from a GPT disk, and some BIOSes have problems recognizing GPT disks. In these cases, you can use a disk management tool to convert the GPT disk to MBR.

Keep in mind that converting a GPT disk to MBR will destroy any data on the disk. Be sure to back up any important data before you begin.

The Difference Between MBR and GPT

There are two main types of partition tables that are used on computers: MBR and GPT. MBR (Master Boot Record) is the traditional partition table type that has been used on PCs for many years. GPT (GUID Partition Table) is a newer standard that is slowly becoming more popular.

So, what’s the difference between MBR and GPT? The biggest difference is that MBR can only support a maximum of 4 primary partitions, while GPT can support up to 128. This can be important if you have a lot of data that you need to store on your computer.

GPT is also more resistant to data corruption than MBR, so it’s a good choice if you’re worried about that. However, it’s worth noting that both MBR and GPT are quite reliable, so you shouldn’t have too many worries about data loss either way.

Ultimately, it’s up to you to decide which partition table type you want to use. If you’re not sure, GPT is probably the best choice since it offers more flexibility and reliability.

How to Convert MBR to GPT Without Data Loss

To convert MBR to GPT without losing data, you need to use a third-party tool like AOMEI Partition Assistant Standard. This software is designed to safely convert MBR to GPT without destroying any data on the disk.

Here are the detailed steps:

Download, install and launch AOMEI Partition Assistant Standard. Right-click the MBR disk and select “Convert to GPT Disk”.

In the pop-up window, click “OK” to continue.

A warning message will pop up, telling you that all data on the disk will be destroyed. Click “OK” to continue.

Click “Apply” and “Proceed” to start the conversion.

After the conversion is complete, you can check that the disk has been changed to GPT in Disk Management.


There are a few key things to remember when converting from MBR to GPT:

1. You will need to backup your data before doing anything.

2. In most cases, you will need to delete all of the partitions on your drive before converting it to GPT.

3. The process of converting from MBR to GPT is not difficult, but it is important to follow the directions carefully in order to avoid any data loss.

4. After converting to GPT, you will be able to create new partitions and use them as you please.
