How to Change GPT Partition Style to MBR Without Losing Data?

We will talk about how to convert a GPT (GUID Partition Table) disc to an MBR, or Master Boot Record, disc without losing any data in this article.

GPT to MBR conversion can be a little complicated because it requires dividing the disc, which could result in data loss if done incorrectly.

But, it is possible to complete the conversion without losing any of your crucial files if you use the appropriate tools and methods.

This article will walk you through the process of converting a GPT disc to MBR and offer advice on how to reduce the likelihood of data loss while doing so.

Prerequisites

Backup of crucial data:

It's crucial to make a backup of every file on the disc that is crucial before starting the GPT to MBR conversion procedure. In the event that something goes wrong during the conversion process, this will guarantee that you can restore your files.

You can back up your data in a number of methods, like by utilising an external hard drive or a cloud storage platform. Before starting the conversion, it's a good idea to check the backup's integrity.

Tools required for conversion:

There are a few tools required to convert GPT to MBR. The Disk Management tool that comes with Windows is among the most used tools for this operation.

Using third-party partition manager software, such AOMEI Partition Assistant or EaseUS Partition Master, is an additional choice. These apps offer a user-friendly interface and more sophisticated partition management functionality.

Verify the disc space and current partition layout:

Check the disk's present partition arrangement and confirm that there is adequate free space before changing from GPT to MBR.

This will enable you to ascertain whether any data loss will result from the converting process. With the Disk Management tool or a different partition manager programme, you can examine the partition layout and available disc space.

Instructions for changing GPT to MBR in detail:

  1. On the GPT drive, make a backup of all crucial data.
  2. Third-party partition management programmes, like AOMEI Partition Assistant or EaseUS Partition Master, to be downloaded and installed.
  3. Choose the GPT disc you wish to convert in the partition manager programme by starting it up.
  4. Choose "Convert GPT to MBR" from the menu.
  5. Make sure you comprehend the procedure and the adjustments that will be performed.
  6. To start the conversion process, click "Apply".
  7. When the procedure is finished, verify the new partition layout to make sure it is accurate.

Recommendations for reducing data loss during the procedure:

  • Before beginning the conversion procedure, make sure that the GPT drive has a backup of all of your crucial data.
  • Employ trustworthy partition manager software to prevent mistakes and data loss.
  • Before beginning the conversion procedure, check the disc space and current partition layout.
  • Before starting the conversion process, go over the changes that will be done.
  • Wait for the procedure to finish before examining the new partition layout.

Common problems and their solutions:

  • If the conversion process fails, try using a different partition manager programme or look for any error messages that can explain the issue.
  • If the new partition layout is incorrect, try reverting to the original one using the partition manager software's "Undo" feature.
  • After the conversion, if the bootloader isn't operating properly, try updating it with a bootloader repair tool.

Verifying for mistakes:

After the conversion process is complete, it is crucial to verify for any mistakes or problems that may have happened.

Incorrect partition layout, bootloader problems, and data loss are a few prevalent errors. You can use a third-party partition management program or the built-in Disk Management tool to check for issues.

It is advised to seek professional help or consult the software's troubleshooting manual if any difficulties are discovered.

Update bootloader:

On occasion, the conversion procedure may result in bootloader problems. It might be necessary to upgrade the bootloader if the computer still cannot boot correctly after the conversion.

Typically, a bootloader repair programme like Boot-Repair or EasyBCD can be used for this. Before doing any additional procedures, it is crucial to make sure the bootloader is operating properly.

Verifying the new partition layout:

It's crucial to check the new partition layout after the conversion process is over and any faults have been fixed.

Use a third-party partition management programme or the built-in Disk Management tool to accomplish this. This will enable you to verify that the new partitions were appropriately created and that there is enough available free space.

Conclusion:

This article has covered how to convert a GPT disk's partitioning scheme to MBR without erasing any data.

Before starting the conversion process, it is crucial to make a backup of any crucial data, and we've outlined how to do so step-by-step using a third-party partition manager programme.
