Don't worry if Windows Setup reports "Windows cannot be installed to this disk. The selected disk is of the GPT partition style" error. Here are three quick fixes that you can apply to get rid of this error from your PC:

1. Convert to MBR via Partition Manager Software - No Data Loss 
2. Convert to MBR Using DiskPart - Request Wiping Disk
3. Reformatting Disk to MBR Using Windows Setup - Request Deleting Partitions

Error: 'Windows cannot be installed to this disk. The selected disk is of the GPT partition style.'

This error is also known as "Windows cannot be installed to this disk GPT" which often occurs during Windows installation on Windows 10/8/7. So what caused the "Windows Cannot Be Installed to This Disk - GPT Partition Style" error on your PC? Let's see.

Windows Cannot be installed on this disk. The selected disk is of the GPT partition style.

Cause of 'The selected disk is of the GPT partition style' Error

During Windows setup, you must choose to install Windows using the MBR or GPT partition style. Also, your hard drive partition style must be set up to support either UEFI mode or Legacy mode:

  • UEFI → GPT
  • Legacy BIOS → MBR (Read further: UEFI vs. BIOS)

When you receive "Windows Cannot be installed to this disk. The selected disk is of the GPT partition style", it suggests that your computer is currently booted in Legacy BIOS mode but your hard drive is not configured for Legacy mode. So the best way out is to convert the GPT partition style disk to MBR to fit the PC's Legacy boot mode.

Fix 'Windows Cannot Be Installed to This Disk' with GPT Partition Style Error - 3 Solutions

As mentioned, the error message indicates that Windows is booted in UEFI mode that requires the system disk to be GPT partition style. The direct solution to "The selected disk is of the GPT partition style" is to change the MBR disk to GPT. After figuring out the reasons, the troubleshooting becomes much easier now. Here, you may follow one of the next three solutions to fix this error on your own.

Method 1. Convert to MBR via Partition Manager Software - No Data Loss 

For the easiest GPT to MBR conversion solution, we strongly advise you choose a non-data-destroying method. Here, a third-party powerful partition tool - EaseUS Partition Master with its disk conversion feature can help. It allows you to convert GPT to MBR without losing data.

You have two options to convert the disk: 1. Convert the disk to GPT on a new computer; 2. Convert the disk to GPT via a WinPE bootable disk. Both data and partitions are safely protected. Let's see the details:

#1. Convert Disk to GPT on a New Computer

Take off your target disk and connect it to a new computer. Install and run EaseUS Partition Master on the new PC to start the disk conversation with the following steps.


Step 1: Install and open EaseUS Partition Master on your Windows computer. 

open EaseUS Partition Master

Step 2: Right-click the GPT disk that you want to convert and select "Convert to MBR". Then, you will add a pending operation.

Step 3: Click the "Execute Operation" button at the top-left corner. Next, click "Apply" and begin to convert GPT disk to MBR. All data is safe with EaseUS partition manager software.

#2. Convert Disk to GPT on Current PC from WinPE Bootable Disk

If you don't have a second computer, you can run the EaseUS partition manager to create a WinPE Bootable disk on a USB flash drive. Then complete the disk conversion process as shown below:

Step 1. Reboot the PC from the USB bootable disk to enter a WinPE environment.

Step 2. On EaseUS Partition Master, right-click the system disk and select "Convert to MBR". Click "OK".

Step 3. Click the "Execute Operation 1" button, click "Apply" to save the changes.

After this, you can continue with the process of installing Windows OS on your target computer again.

Method 2. Convert GPT to MBR Using Diskpart - Request Wiping Disk

The other way that you can try is to run Diskpart and convert the disk to GPT by booting up the PC via a Windows installation DVD or USB. This method needs you to manually wipe a drive and convert it to GPT. 

Note: If the data matters, go back to Method 1 and convert to MBR using EaseUS Partition Master, preserving your data.

Let's see how to convert GPT to MBR with the following steps:

Step 1. Turn off the PC and plug in the Windows installation DVD or USB.

Step 2. Boot the PC from the DVD or USB.

Step 3. In Windows Setup, press "Shift + F10" to start Command Prompt.

Step 4.Type the following command in order and hit Enter each time:

  • diskpart
  • list disk
  • select disk
  • clean
  • convert mbr

Step 5. Type exit to close Diskpart Command Prompt.

Step 6. Continue the Windows installation.

After the conversion, the drive will appear as a single area of unallocated space. Choose the unallocated space and click Next. Windows will begin the installation without sending the same error.

Method 3. Reformatting Disk to MBR Using Windows Setup - Request Deleting Partitions

The last way that you can try is to turn to Windows Setup that allows you to delete partitions and reformat the disk to MBR while installing Windows OS. Here are the steps:

Step 1.Boot PC from Windows installation USB or disk.

Step 2.Click "Custom" while prompt choosing an installation type.

Step 3. Select each partition on the target drive and click "Delete" on the Where do you want to install Windows screen.

Step 4. Once you delete all partitions, select the unallocated space and click "Next". 

Windows will detect the target disk and reformat to use it as an MBR partition style, and then begin the installation. All you need is to wait patiently to complete the installation process.

The selected disk is of MBR partition style.

To fix this issue, you can only convert MBR to GPT since legacy BIOS is not supported by the computer.

Fix Windows Cannot Be Installed to This Disk GPT Is Possible Now

On this page, we explained that when installing Windows, using the MBR or GPT highly depends on your computer firmware UEFI-GPT or BIOS-MBR.

If you get a BIOS-based computer, you can only install Windows on an MBR disk. If you get a UEFI-based PC, choose GPT instead. Therefore, it's the disk partition style issue when you get "Windows Cannot be installed to this disk. The selected disk is of the GPT partition style." error message during the Windows installation process.

On this page, we provided 3 ways to help you fix this issue. For the easiest and most secure way out, EaseUS Partition Master deserves your trust. No data or partition loss will happen.

Extended Reading: What Is GPT Partition Style

According to some Windows users who have "Windows cannot be installed to this disk. The selected disk is of the GPT partition style" error, they also have related concerns about the GPT partition style. Continue reading to learn more about it. 

What Is GPT Partition Style? 

GPT is part of the UEFI standard, which means a UEFI-based system should be installed on a GPT disk. GPT partition style allows you to create theoretically unlimited partitions on the disk and enables you to fully use disks that are larger than 2TB. Besides, compare GPT and MBR, GPT is safer and has better compatibility with modern hardware.

How do I get rid of GPT partition style?

You cannot get rid of a GPT partition style. A partition style is necessary for Windows to access the data on the device. But you can change the GPT partition style to MBR by conversion with provided methods as shown above. 

How do I create a GPT partition?

The partition style of the disk is decided when you first initialize it. When you initialize a disk, you need to choose GPT so as to create a GPT partition. If you have set the disk as MBR, you can convert the MBR disk to GPT so as to create GPT partitions.
