However, for those less tech-savvy, careful reading is necessary to avoid confusion during installation and troubleshooting.

I. Causes of 'Windows cannot be installed to this disk'
The error arises from a conflict between BIOS and the disk format used for Windows 10 installation. Most computers use EFI (UEFI) BIOS, but Windows requires the GPT format, while your disk may be in MBR format. Changing the disk format to GPT is necessary to resolve this issue.

II. Fixing the Error: 'Windows cannot be installed to this disk'
Note: Changing the disk format will result in the loss of all data on the drive.
1. Change the Disk Format Using Command Prompt
Step 1: In the Windows setup interface, press Shift + F10 to open the Command Prompt.

Step 1: If you are in the normal Windows desktop interface, type CMD into the search bar and select Run as administrator to open it.

Step 2: Next, enter the command Diskpart to switch to disk mode.

Step 3: Now, you need to enter the command “list disk” to display a list of all the physical drives on your computer.

You now have a list of all the physical drives on your computer. Your task is to identify the correct drive for Windows installation based on the drive's capacity. Once identified, take note of the drive's name (in the Disk ### column).
For instance, in this scenario, we're installing Windows on Disk 2.
Step 4: Proceed by entering the command Select “name of the drive for Windows installation”.
Example: If you're installing Windows on Disk 2, you would enter the command “Select Disk 2”.

Step 5: Once you have selected the correct drive for Windows installation, enter the command Clean to wipe all data inside the drive before converting the format.

Step 6: Once the drive is cleaned, proceed to use the command “Convert GPT” to change the format for the drive.

Step 7: At this point, you have completed the format conversion to GPT. For added certainty, let's double-check by using the command “list disk”.
Now you will see a list of drives, and our drive will have a checkmark in the GPT column. (In this article, it's Disk 2, so there will be a checkmark in the GPT column).

Step 8: Finally, close the Command Prompt window and Click on Refresh to update the system with the new format for the drive. Afterward, proceed with the Windows installation as usual.

Step 3: Right-click on the drive and choose Delete Volume....
On the Windows operating system, there is a built-in tool to change the drive format, without the need to install any additional software on the computer.
Step 1: Right-click on the Start Menu and select Disk Management.

Step 2: Right-click on the drive you want to convert the format for and choose Delete Volume...

Step 3: Finally, right-click on the drive and select Convert to GPT disk to switch from MBR to GPT format. After the conversion, you can use the drive as usual.
