When you encounter the prompt "Windows cannot be installed to this disk. The selected disk is of the GPT partition style", 1. First check whether the motherboard supports UEFI. If supported, enable UEFI and set it to priority boot mode; 2. If UEFI is not supported, you need to use the diskpart tool to convert the disk from GPT to MBR format through the command prompt (the data will be cleared); 3. It is recommended to use UEFI mode to install, and make sure that the USB disk supports UEFI boot. Pay attention to backing up the data before operation and confirm that the disk selection is correct.
You encounter the prompt "Windows cannot be installed to this disk. The selected disk is of the GPT partition style" usually because you are trying to install Windows in traditional BIOS mode, but the hard disk uses the GPT partition table. The key to solving this problem is to match the boot method and disk partition format .

Below are some practical suggestions to help you install the system smoothly.
Check whether the motherboard supports UEFI
If your hard drive is in GPT format, you must use UEFI boot to install Windows. Traditional Legacy BIOS mode does not support GPT disk booting.

- The method to enter the BIOS is usually pressing the Del, F2, F10 and other keys when powering on.
- Check if there are "UEFI Boot" or similar options in the Boot or Startup tab
- If UEFI is supported, remember to enable it and set the startup sequence to UEFI priority
If UEFI is not supported, you cannot install a 64-bit Windows system on this GPT disk, and you need to convert the disk to MBR format (see below).
Convert disk to MBR format (suitable for cases where UEFI is not used)
If your motherboard does not support UEFI, or you insist on using Legacy mode to install the system, you need to convert the GPT disk to MBR format.

⚠️Note: This operation will clear all data on the disk, please backup in advance!
The operation method is as follows:
- Click "Repair Computer" > "Troubleshooting" > "Advanced Options" > "Command Prompt" on the installation interface
- Enter the following command and press Enter:
-
diskpart
-
list disk
-
select disk X
(X is the disk number of the system you want to install) -
clean
-
convert mbr
-
After completion, you can select the disk normally for installation.
Install Windows using UEFI mode (recommended practice)
If your computer supports UEFI, the safest way is to switch to UEFI mode and retain the GPT disk format to continue installation.
The operation steps are as follows:
- Make sure UEFI mode is enabled in the BIOS
- The USB drive boot disk needs to be in FAT32 format and contains UEFI boot files (most USB drives made by official tools meet the requirements)
- After inserting the USB drive, boot from the UEFI device
- Continue the installation process, and you can normally identify the GPT disk and install it in partitions.
If you are not sure whether the USB drive supports UEFI, you can use tools such as Rufus to recreate a UEFI-compatible boot disk.
Small details reminder
- 64-bit Windows must be combined with UEFI GPT to perform all functions , such as supporting hard disks larger than 2TB.
- If you still cannot recognize the hard disk in UEFI mode, it may be a driver problem. You can try loading the storage controller driver
- Before clearing the disk, be sure to confirm that it is not an error operation, especially if there are multiple hard disks, do not select the wrong disk.
Basically all this is the problem itself, but the corresponding relationship between the boot method and the disk format is easy to ignore.

If there is no progress for a long time, you can force shut down and enter the recovery environment (WinRE) multiple times, and try to start repair or system restore. 3. After entering safe mode, you can uninstall the most recent update records through the control panel. 4. Use the command prompt to execute the bootrec command in the recovery environment to repair the boot file, or run sfc/scannow to check the system file. 5. The last method is to use the "Reset this computer" function
