How to convert MBR to GPT without Losing Data Windows Server
Converting MBR to GPT is one thing but knowing how to convert MBR to GPT without losing data windows server is another. GPT stands for GUID Partition Table and MBR is Master Boot Record. Conversion between the two is usually impossible without having to delete the existing partitions through diskpart.
However, the GPT is more reliable and possesses other advantages over the MBR. Microsoft even just officially announced that the Windows 11 OS requires only a UEFI/GPT partition style. That makes the GPT even more desirable. Other standout benefits of the GPT are:
- Higher Disk Capacity: the MBR can only support a maximum of 2TB compared to the 256TB capacity of the GPT.
- More Partition Slots: the maximum of 4 primary partitions of the MBR is lower than the 128 primary partition slots of GPT.
- Firmware Support: the GPT uses a UEFI interface over the BIOS type for the MBR.
Therefore, the process of how to convert MBR to GPT without losing data window server is essential and that’s what this guide explains. Keep reading!

Step 1. Use the Windows + R command and enter cmd in the resulting dialogue box. Press Enter to open the command prompt.
Step 2. On the command prompt, type diskpart and hit Enter to run the in-built DiskPart tool.
Note: Verify you have done a backup of all essential files and programs before proceeding to the next step.
Step 3. Delete all disk/volume partitions on the MBR drive. You can use the CLEAN ALL command to erase every stored data from the cmd menu.
Step 4. Input “list disk” and click Enter. All available disks will display. Navigate and choose the ones you wish to convert to GPT.
Step 5. Assuming “Disk 1” is the MBR disk to be converted, type “Select Disk 1” and press Enter. The DiskPart tool will notify you that Disk 1 has been selected.
Step 6. Type convert gpt and press Enter to submit. Wait for a few seconds and a display message will appear saying “DiskPart successfully converted the selected disk to GPT format”.
Step 1. Enter disk management by pressing Windows + R and typing diskmgmt.msc in the dialogue box. Press Enter and the disk management tool will open.
Step 2. From the Disk Management environment, scroll to the MBR disk you need to covert. Right-click on the different partitions and choose the Delete Partition/ Delete Volume option. Without that, the disk management tool will not display the Convert to GPT disk option.
Step 3. The disk should now be left with only unallocated space. Right-click on it and choose the Convert to GPT disk option.
Step 4. Proceed to create new volume/disk partitions on the GPT drive. You can also consider restoring from a backup device (provided you did backup before starting the conversion process).
