How do I Fix The Selected Disk is of the GPT Partition Style

When installing a new Windows operating system, encountering errors can be frustrating. One common error message that users may face is “Windows cannot be installed to this disk. The selected disk is of the GPT partition style.” This error indicates a conflict between the partition style of the disk and the installation process. In this article, we will delve into the differences between GPT (GUID Partition Table) and MBR (Master Boot Record) partition styles, understand their advantages and limitations, and explore the steps to resolve the error during the Windows installation process.

GPT and MBR Partition Styles: An Overview

The partition style of a disk is a crucial aspect of disk management that determines how the disk organizes data and enables the operating system to access it. Both GPT and MBR are widely used partitioning schemes, but they have distinct characteristics:

  • GPT (GUID Partition Table): GPT is a modern partitioning scheme that offers several advantages over MBR. It supports larger disk sizes (more than 2TB), allows for more partitions (up to 128 primary partitions), provides better data redundancy, and uses a globally unique identifier (GUID) for each partition.
  • MBR (Master Boot Record): MBR, on the other hand, is the traditional partitioning style used on older systems. While it has served well for many years, it has some limitations, such as support for disk sizes up to 2TB and a maximum of four primary partitions. However, MBR is compatible with a wider range of systems, including both older BIOS-based systems and newer UEFI-based systems.

Reasons for the Error:

When attempting to install Windows on a disk, it must be formatted with a partition style that the operating system recognizes. If you encounter the error message “Windows cannot be installed to this disk. The selected disk is of the GPT partition style,” it means that your system is trying to install Windows with the wrong partition style.


Let’s explore some solutions to resolve this issue:

GPT Partition error

Solution 1: Convert GPT to MBR:

One way to install Windows on a GPT partitioned disk is to convert it to MBR. However, keep in mind that converting the partition style will erase all data on the disk. If you have valuable data on the disk, back it up before proceeding. To convert the disk, follow these steps:

  1. Backup Your Data: Ensure all critical data on the disk is safely backed up to avoid data loss.
  2. Access Command Prompt: During the Windows installation process, press Shift + F10 to open Command Prompt.
  3. Diskpart Utility: Use the diskpart command to access the disk partitioning utility.
  4. List Disks: Type list disk to display a list of available disks. Note the disk number of the target disk.
  5. Select Disk: Type select disk X (replace X with the appropriate disk number).
  6. Clean Disk: Type clean to remove all partitions and data from the selected disk.
  7. Convert to MBR: Enter convert mbr to convert the disk to the MBR partition style.
  8. Exit Command Prompt: Type exit to close Command Prompt.
  9. Retry Installation: Exit the Command Prompt window and resume the Windows installation.

Solution 2: Use UEFI Boot Mode:

Modern systems often use the Unified Extensible Firmware Interface (UEFI) instead of the older BIOS firmware. UEFI supports GPT partitioning and offers enhanced security and features. To use UEFI boot mode, follow these steps:

  1. Access BIOS/UEFI Settings: Restart your system and enter BIOS/UEFI settings by pressing the designated key (often F2, F12, or Delete) during startup.
  2. Change Boot Mode: Locate the Boot Mode or Boot List Option and change it from Legacy/BIOS to UEFI.
  3. Save Changes: Save the changes and exit the BIOS/UEFI settings.
  4. Retry Installation: Restart the system and try reinstalling Windows.

Solution 3: Convert a Bootable Pendrive from NTFS to FAT32


In conclusion, encountering the error “Windows cannot be installed to this disk. The selected disk is of the GPT partition style” is not uncommon but it can be resolved. Understanding the difference between MBR and GPT partition styles and implementing the appropriate solutions will enable you to successfully install Windows on your disk. Always remember to back up your data before making any changes to your disk partitioning.
