How to convert a MBR partition in GPT through using command prompt

This article is all about how to convert your MBR partition into GPT through using command prompt in Windows. After reading this article you will be able to convert your hard disk partition from MBR to GPT. When you are initializing a new hard drive in Windows built-in-disk Manager, a window pops up and asks you to choose between MBR (Master Boot Record) and GPT (GUID Partition Table) disk. There are two different ways of storing the partitioning information on a drive that is MBR and GPT. The default setting of windows would initialize the disk to MBR partition style. The MBR is an old and commonly used disk layout but it has some limitations. So, we convert our MBR partition into GPT through using command prompt.

First of all we learn some basic knowledge about MBR and GPT partition so let’s start here

1. MBR Disk Layout

MBR (Master Boot Record) is an old commonly-used disk layout which is used as default in windows. Firstly MBR is introduced with IBM PC DOS 2.0 in approx 1983. MBR works with disks up to 2 TB in size, But it can not handle disks with more then 2 TB of space. With MBR disk layout you can only create four primary partitions. If you want to create more than four partitions then first of all you convert a primary partition into Extended partition then create logical partitions inside it. This is the drawback of MBR so we introduce a new disk layout named as GPT.

2. GPT Disk Layout

GPT (GUID Partition Table) is a new standard that’s gradually replace MBR. It is associated with UEFI. It does not have limitations like MBR. GPT allows you to create unlimited partitions on your system without creating a extended partition. In windows you can allows up to 128 partitions on a GPT drive. On an MBR disk Partitioning and boot data is stored in one place and in a GPT disk multiple copies of this data stored across the disk. It is much more durable and also can recover if the data is corrupted. So, we use GPT in computers instead of MBR.

Now we learn that how to convert a MBR partition into GPT through using command prompt. So let’s start here.

Note: – This process erase all of your data from hard disk so always create a backup of your data before proceed this process.

Step 1: – First of all we open command prompt using Windows key+X and the choose command prompt (Admin) option to open command prompt as admin.

Step 2: – After that your command prompt will be open now type diskpart command in it and press enter to proceed.

Step 3: – After that type list disk command in command prompt and then press enter to proceed.

Step 4: – After that type select disk 0 command in command prompt and then press enter to proceed. This command helps you in select the disk which you want to convert into GPT.

Step 5: – After that type clean command in command prompt and then press enter to proceed . This command format your disk and your all data will be cleaned from that disk because without erase all data from your disk you can not be able o convert your disk into GPT.

Step 6: – After that type Convert GPT command in your command prompt and then press enter. This command helps you in convert your disk from MBR to GPT. But it erase all the data from your hard disk including your boot files and windows files. Now put a bootable pendrive or a bootable CD in your system and then again install an operating system on your computer then your disk will be converted into GPT from MBR.

If you want to convert your disk partition at the time of window installation simply open command prompt at the time of partition creation and then press shift+f10 to open command prompt on your screen and then follow above given steps from 1 to 6.
