The error message “The selected disk is GPT partition style” may be displayed when installing the Windows operating system on a GPT-style disk, see illustration below. You will be asked why Windows can not be installed on this GPT disk. Generally, the main cause is the motherboard. There are two types of boot modes: BIOS boot mode and UEFI boot mode. Most versions of Windows have the Unified Extensible Firmware Interface (UEFI) boot mode, while some versions since the old version of Windows XP have the Basic Input Output System (BIOS) boot mode. Due to different boot modes, there are two types of partitioning schemes: MBR (Master Boot Record) and GPT (GUID Partition Table). If you want to boot the system from a GPT disk, the motherboard must support UEFI. while on the BIOS, you must use the MBR partition table. Thus, if you install Windows on the BIOS system, the GPT partition table is in your path. The installation will be blocked by the error.

How to fix Windows cannot be installed to this disk issue

Solution 1: Delete Your Partitions

If the partition of your hard disk has been partitioned on the MBR partition, the best thing to do is to delete your partitions. This method is recommended only for users who are willing to lose their data on their drive. For example, if you are doing a new job, look at this!

Insert the installation media and start the computer. Configure the language, time and date settings, etc.

If you have never installed Windows 10 on this computer before, the Windows Activation screen appears. Enter your Windows 10 key here. If you do not have one, but you have a valid key 7, 8 or 8.1, enter it here. You can also skip this part after the installation is complete.

Follow the installation process “What kind of installation do you want?” Screen. Select the “Custom” option to make sure that you are performing a clean install and not an upgrade.

You will now see “Where do you want to install Windows?” Screen with the partitions you have active. Choose each of them with the current system files of the operating system and click Remove. Choose the one where you want to install Windows and follow the process. The error should no longer appear.

Solution 2: Change Boot Order to DVD

This method has also helped many users and its advantage is that it is not necessary to delete anything. However, you will need to edit some BIOS settings for the boot manager to first check the DVDs!

1. Turn on your computer and immediately press the BIOS Setup key on your keyboard immediately, about once every second, until the Computer Setup Utility or BIOS settings appear. This key will be shown on your screen as Press _ to run the installer.
2. Use the right arrow key to move to the Security menu when the BIOS Setup window opens, use the down arrow key to select Secure Boot Configuration from the menu, and press Enter. These options are sometimes located under System Configuration or on the Security tab.
3. Before you can use this option, a warning will appear. Press F10 to continue to the Secure Boot Configuration menu. Use the down arrow key to select Secure Boot and the right arrow key to change this setting to Disable.
4. Use the down arrow key to select Legacy Support, then use the right arrow key to change to Enable.
5. Under the Legacy Boot Order settings, select your USB CD / DVD-ROM drive and use the appropriate keys (explained at the bottom of the screen to add this option at the top of the boot sequence to make sure you start at If this option is available, be sure to disable the EFI / UEFI boot sources.
6. Press F10 to save the changes. Use the left arrow to access the File menu, use the down arrow to move to Save Changes and Exit, and press Enter to select Yes.
7. The Computer Configuration Utility will now be shut down and the computer should restart. When the computer has restarted, try installing the Windows installation again to see if the problem persists.

Solution 3: Clean the Disk and Convert it to GPT

If the above methods failed, you can still use Command Prompt and DISKPART to clean the drive completely and easily convert it to GPT. Note that this process will also erase the drive, so make sure everything is backed up

If your computer system is down, you will need to use the installation media used to install Windows for this process. Insert the installation drive you have or just created and start your computer.

You will see a window Choose the layout of your keyboard to choose the one you want to use. The Choose an option screen will then appear navigate to Troubleshooting >> Advanced Options >> Command Prompt.

In this command prompt window, simply type “diskpart” into a new line and hit the Enter key to execute this command.

This will change the command prompt window to allow you to run various Diskpart commands. The first one you will execute is the one that will allow you to see the complete list of all available volumes. Type this and make sure to click Enter:

DISKPART> list

Make sure to choose your DVD player carefully, according to the number assigned to it in the volume list. Let’s say its number is 1. Now, run the following command to select your USB key:

DISKPART> select volume 1

A message should appear and say something like “Volume 1 is the selected volume”.
