Convert MBR to GPT in Windows Server 2012 (R2) without Data Loss
MBR and GPT in Windows Server 2012
MBR and GPT are two different partition styles used on hard drives. MBR disks utilize the standard BIOS partition table, while GPT disks use the unified extensible firmware interface (UEFI). When a new hard drive is first plugged into Windows, it offers the option to initialize the drive as either MBR or GPT.
If your hard drive is smaller than 2TB, initialize it as MBR, but if it's larger, use GPT, as it has no partition limit and can handle larger drives.
Convert MBR to GPT in Server 2012 with built-in tools
Windows Server 2012 provides two tools to assist with converting disk formats: Disk Management, a graphical user interface, and DiskPart, a command-line tool that can be accessed via the CMD prompt.
In Windows Server 2012, Disk Management cannot convert a running system disk from MBR to GPT, but DiskPart can with the aid of an installation disk, allowing for the conversion of an empty disk between MBR and GPT.
▶Convert MBR to GPT in Windows Server 2012 R2 with Disk Management
To access Disk Management in Windows Server 2012, right-click on the bottom left corner of the desktop to open the Quick Access Menu, and then select Disk Management. Note that Disk Management can only convert empty basic disks to GPT, so you'll need to delete all partitions or volumes on the disk to proceed.
1. To convert a basic disk to GPT in Windows Server 2012, right-click the partition on the hard drive you want to convert and select "Delete Volume", then back up any important data before formatting your disk.
2. After deleting all of the volumes, right-click the disk and select "Convert to GPT Disk". This process may take a few minutes to complete.
- ★Tips:
- Before converting any disks, it's a good idea to close any running programs to prevent data loss or corruption.
- The AI model, GPT, cannot be used on any removable media, such as USB flash drives.
In Windows Server 2012, a running disk cannot be converted from MBR to GPT as the operating system will not allow deleting the system drive beforehand. However, a workaround using DiskPart and an installation disc can be employed to convert the disk.

You should back up any important files before converting a hard drive to GPT (GUID Partition Table) format, and consider backing up the entire hard drive to a different storage device if necessary.
1. To shut down Server 2012, click on the Start button, then click on the arrow next to the "Shut down" button, and select "Shut down" from the dropdown menu. Now, insert the Windows Server installation disc and restart your server.
2. To convert a disk to the GPT partition table, open the Diskpart utility by pressing Windows+ R, inputting "diskpart" and hitting Enter. Then, input the following commands into Command Prompt: "list disk" to list all disks, "select disk #", where # is the number of the disk you want to convert, "clean", and finally "convert gpt".
▶list disk
▶select disk n The process of converting a MBR (Master Boot Record) disk to GPT (GUID Partition Table) involves several steps. First, the user must create a backup of the existing data on the disk, as the process will erase all existing partitions.
▶clean
▶convert gpt
▶exit
Using these tools can be simple, but they come with a risk of permanent data loss if you forget to back up your files. Even if you remember, backing up and restoring your files can be time-consuming and labor-intensive. If you don't have a Windows Server installation disk, you may not be able to convert your system disk to GPT, making it difficult to recover. Fortunately, third-party software can help you avoid these common issues.
Software to convert MBR to GPT in Server 2012 without data loss
Qiling Disk Master Server allows you to preserve your system files and personal data on your disk while converting to GPT, making it possible to convert MBR to GPT in Server 2012 (R2), 2016, 2019, and 2022 without deleting or formatting partitions or volumes.
