How to Convert GPT Disk to MBR Disk without format

Solution 1: Convert GPT disk to MBR disk with EaseUS Partition Master

EaseUS Partition Master can directly convert GPT disk to MBR disk without any data loss (hard disk with system installed is not supported). You can also use EaseUS free partition software to solve other partitions cases such as to move gpt partitionpartition gpt disk. Compared to Disk management and command prompt, it won't require to deleted disk volumes. Therefore, it is the safest and the most reliable way.
Note: If you want to convert MBR system disk to GPT, you will need EaseUS Partition Master Professional.
1. Launch EaseUS Partition Master.
2. Select the GPT disk that you want to convert to MBR disk. And then click "Convert GPT to MBR".

3. Choose "Apply", you will see that the GPT disk has been converted to MBR disk.
All data is safe with EaseUS partition manager software.

Solution 2: Convert GPT disk to MBR disk with Windows Disk Management

1. Right click "My Computer" and choose "Manage" -> "Storage" -> "Disk Management".
2. Right-click the GPT hard disk which you want to convert to MBR disk and choose "Delete volume".
This action would cause data loss if there are important data in your disk volume. And it's highly recommended for you to backup important data in GPT before deleting volumes on it.
Delete all volumes
3. Right click on the GPT disk (which becomes new volume after deleting all volumes on it) and choose "Convert to MBR Disk".
After you convert GPT disk to MBR disk, you can create partitions on the now MBR disk if you like.

Tips to convert gpt to mbr with Disk Management and Command Prompt:
1. You must have administrator privilege to do this in Windows.
2. Before you convert a disk, be sure to backup anything on the GPT disk that you want to convert to MBR disk. Converting the disk requires that all partitions and volumes are deleted on the disk first.

Solution 3: Convert GPT disk to MBR disk via diskpart command

In the following case, I would like to introduce you detail steps about how to convert GPT to MBR with diskpart command. Let's take how to conbert disk 1 to MBR for example.
1. Input "DiskPart" at the search bar. Type list disk and press enter.
diskpart command: list disk
2. Type select disk 1 and press enter. Type detail disk and press enter.
This will give you a list of all the volumes on the selected disk. If you do not have any volumes listed, then you can go to step 4.
diskpart command: detail disk
3. Type select volume 5 and press enter. Type delete volume and press enter.
Repeat steps 3 for each volume listed in step 2 until you have deleted all the volumes.
4. Type select disk 1 and press enter. Type convert mbr and press enter.
diskpart command: convert GPT disk to MBR disk
5. Type exit and press enter.
Now you’ve successfully converted gpt to mbr. If you do not waste time backuping up data, EaseUS Partition Master can be your best choice. You can also read the tutorial of converting MBR disk to GPT disk.
