3 Methods to Fix The Selected Disk Is of The GPT Partition Style

In this article, we have discussed the critical questions that people are fed up with, such as- what are the Cause of 'The Selected Disk Is of The GPT Partition Style,' the Differences Between GPT and MBR?

If you want to change the disk partition from GPT to MBR and the selected disk is of the gpt partition style, you can go through this article, we have talked some of the tested and finely working tutorials that will surely help you out.

Cause of 'The Selected Disk Is of The GPT Partition Style'

In your computer, if the prompt is saying, ". The selected disk is of the GPT partition style", it is because your computer is booted in UEFI mode, and the hard drive is not compatible and configured for UEFI mode.


What's the Differences Between GPT and MBR?

MBR table scheme is available on computers with UEFI / EFI installed (not BIOS), and GPT or GUID Partition Table is the updated version of it.

If the computer is installed with BIOS and not with UEFI / EFI, GPT may also be used.

The following are advantages of these disks:

  • On an MBR disk, there could be a partition of - 128 partitions vs. four partitions.
  • On an MBR disk, the maximum allowed space on a single partition can have up to 256Tera Byte vs. 2Tera Byte

The following versions of Windows can read GPT disks:

  • Windows 8
  • Windows Vista
  • Windows 7
  • Windows Server 2003 and Server 2008
  • Windows XP 64-bit

From Windows, these disks can also be booted. The versions that are listed below can be booted from GPT.

  • 64-bit Windows versions will boot from GPT:
  • Windows 8,
  • Windows 8.1,
  • Windows 7,
  • Windows Vista and Windows Server editions.

** Note that if your computer has UEFI / EFI installed, then only you can boot the windows from GPT.

The removable USB drives cannot be converted to GPT as these removable disks are set as an MBR.


Fix 'the selected disk is of the GPT partition style'

Method 1: Change Device Boot Mode to Native UEFI

The solution that is given below is universally applicable because all the computers do not have the compatibility firmware with both UEFI and BIOS. If you are also receiving a message like "The selected disk is of the GPT partition style", what that means is your computer is currently booted in "legacy BIOS".

Firstly, you have to confirm if the firmware supports UEFI in BIOS or not, and if the mode is available, you want to boot to UEFI. Down below there is a step by step process that you need to follow if you're going to 'Fix the selected disk is of the gpt partition style.'

  • Now, you need to type "diskpart" followed by pressing the Enter key. This will open the "diskpart" program.

Once you are done with the above process, you can use the syntax to convert the disk to MBR. There is an example down below depicting how you can convert disk 1 to MBR disk.

Step 1 - To check if there is any volume left on the GPT disk, you need to type "list volume" in the Diskpart command line prompt. Once you do this, you can see the list of all the volumes.

Step 2 - Now you need to type "list disk" followed by pressing "Enter." By doing this, you will get the list of all the disks on your computer. You have to remember which drive you want to convert.

Step 3 - Now that you have done all the above processes, you need to type "select disk 1" and press "Enter" so that you can select the disk.
