GPT (GUID partition table) is a replacement of MBR (Master boot record). There are many advantages to using GPT since it allows you to create more than four primary partition and it supports disk larger than 2TB. In this blog, I will elaborate the process that convert MBR to GPT in command prompt.
GPT is more flexible than MBR and uses Unified Extensible Firmware Interface (UEFI). Windows 10, 8.1, 8, 7, Vista, XP x64 and Windows Server 2003 SP1 ( and above versions) can use GPT disks for data but GPT disk supports booting only from 64-bit versions of Windows on UEFI system.
MBR to GPT conversion requires no volume or partition on a disk so users had better backup their data in order to avert data loss. Easy steps that will convert MBR to GPT in command prompt are listed below:
Step 1. Open command prompt in administrative mode.
Step 2. Type diskpart command as shown below, diskpart.exe will convert MBR to GPT
Step 3. In diskpart command prompt, type list disk as shown in below figure. This command will display all disks with their information like size, free space etc.
Step 4. In this step, type select disk <disknumber>, this command will select a disk from available disks and convert it from MBR to GPT partition.
Step 5. After selecting a disk, type clean, the command will delete all volumes and partitions from a disk.
Step 6. Now type convert gpt command as shown in below image, this command will convert empty MBR disk to GPT disk.
Type exit and press enter. This process will successfully convert MBR to GPT in command prompt.
