Summary:
Here you can find reasons and full solutions to fix "Windows cannot be installed on this disk. The selected disk is of the GPT partition style". Try these methods when you failing to install Windows 10/8/7 or other versions due to this error.

When you try to install Windows 10/8/7 on your computer, and the Windows Set up might reposts "Windows cannot be installed to this disk. The selected disk is of the GPT partition style." This is one of the common errors occur during Windows installation
Recently, it seems to become severe in Windows 10. Because there are more and more users are looking for an effective way to install Windows 10 on GPT partition. Here we will analyze the reasons and offers two efficient ways to fix the issue.

Reasons for "The Selected Disk is of the GPT Partition Style" error

MBR and GPT are two formats of the hard disk. MBR stands for Master Boot Record and GPT stands for GUID Partition Table. It is the traditional partition structure to manage disk partitions, and it is widely used by a majority of users due to its compatibility with most systems. GPT partition style is a newer standard for disk partitioning, which defines partition structure by GUID. It is part of UEFI standard, which means the UEFI-based system should be installed on GPT disk. 

And in order to boot Windows from GPT, you should do two things. First, make sure your PC is booted in UEFI mode. Second, make sure that the motherboard of the device supports UEFI. If not, it is better to use MBR to boot from. So, when you get "The Selected Disk is of the GPT Partition Style" error in Windows 10/8/7 or other previous Windows versions, please first check if your PC is booted in UEFI mode. If no, please do it.

Steps to boot into UEFI mode

  1. 1. Reboot PC and enter BIOS.
  2. 2. Enable UEFI boot > Save settings and exit BIOS.
  3. 3. Continue to install Windows.

And if yes, it might suggest that your hard drive is not configured for UEFI mode. Here you have two choices to fix the issue.

  5. 5. Press Enter.
  6. 6. Press F10, and select Yes to save the change and exit the BIOS.

Option 2. Convert GPT to MBR

If the first method doesn't help too much, converting GPT to MBR disk can do you a great favor. It is an easier way to fix "The Selected Disk is the GPT Partition Style" error. And you can do it by using Diskpart or EaseUS free partition software. The latter one is a better choice because it allows you to manage this job without deleting partitions or losing data.
