Master Boot Record (MBR) disks use the standard BIOS partition table. GUID partition table (GPT) disks use the Unified Extensible Firmware Interface (UEFI). MBR disks don't support more than four partitions on each disk. The MBR partition method isn't recommended for disks larger than 2 terabytes (TB).
To complete the disk conversion from the command line with the diskpart disk partition process, follow these steps.
Back up or move the data on the GPT disk prior to conversion.
Open an elevated command prompt: select and hold (or right-click) Command Prompt, and select Run as Administrator.
At the prompt, enter diskpart to initiate the disk partition process.
Prepare the GPT disk for conversion by cleaning (deleting) any partitions or volumes.
Note
If the GPT disk doesn't have any partitions or volumes, skip to the last step to apply the conversion.
At the DISKPART prompt, enter list disk. Make a note of the GPT disk number that you want to convert to MBR format.
At the DISKPART prompt, enter select disk <disk-number>, where <disk-number> is the GPT disk number to convert.
At the DISKPART prompt, enter clean to delete all partitions and volumes on the disk.
At the DISKPART prompt, enter convert mbr to convert the GPT disk to the MBR partition format. |
