"Best Partition Manager out there" by hockemoto
have used this program to resize, create, delete, format and even once, rebuild the MBR. This was across 4 large drives of different makes on 11 different partitions. All this was done rather quickly, without any data loss.

Change MBR to GPT without data loss on windows server

The hard disk 1 (3TB) in my Windows Server 2003 computer is divided into 4 parts, and there are heaps of data stored in those partitions. I want to make best use of space in the disk. But obviously, it is hard for this MBR partitioned disk. Therefore, I want to perform disk conversion. Is there any way to change MBR to GPT without data loss on Windows Server?
 

How to Realize Disk Conversion

The disk conversion refers to the process to convert a MBR (Master Boot Record) disk to a GPT (GUID – Globally Unique Identifier) disk, which can be realized by Disk Management tool or Diskpart exe. All Windows can boot from a MBR disk, while users can only boot from a GPT disk if the motherboard has an enabled UEFI BIOS. Compared with MBR, GPT is preferred most of times, and one of the possible reasons is that MBR disks support up to 2TB per single partition, while GPT disks support up to 256TB per single partition.
 
Affected by the irreversible fashion of GPT, many computer users whose motherboard is UEFI have converted their MBR disks to GPT disks. In terms of adopted means, different users have different preferences. Here, we would like to take the typical method as an example – using diskpart exe.
 
By making use of “delete volume” and “convert gpt” commands, users can fulfill specified MBR disk to GPT disk conversion, and the detailed operations steps are demonstrated as follows:
1. Click under Start > Run, and then enter “cmd” to open Command Prompt Tool.

2. Here, type “diskpart” and press Enter.

3. In this console, type “list disk” to let the toolkit list out recognized disks and then make a note of target disk number.
4. Choosing the disk to be converted, users need to type “select disk n” (n represents the target disk number) and then “detail disk”.
5. Perform deletion operations for all displayed volumes with “select volume” and “delete volume” commands, and then type “select disk n” to continue.
6. After all volumes are deleted, users can realize disk conversion with “convert gpt” command. Note: Make a full backup of data in the chosen disk, for volume deletion will inevitably bring data loss.
 
As the demonstration shows, using diskpart to convert Windows Server MBR disk is complicated to operate for inexperienced computer users. Once misoperations are done, unexpected troubles will be brought. Here, a better way is recommended for users – adopting third party server partitioning software and professional MiniTool Partition Wizard Server Edition is of high recommendation. Let’s see the magic of the software.
 

MiniTool Greatly Simplifies Disk Conversion

Follow the demonstrated guide below, users can easily get a MBR disk converted.
Step 1. Download and install the powerful server partition manager. Then, launch the software to open its main interface:

Step 3. Here, users can see that the chosen MBR disk has been changed to GPT disk and several pending operations in “Operations Pending” area. Since it is only preview effect, users need to click “Apply” button to make final confirmation.
 
It is quite easy to convert MBR to GPT under Windows Server 2003 with the recommended powerful MiniTool Partition Wizard. For more detailed information, please reference the quick link here.
