Windows Cannot Be Installed to GPT Disk

While installing Windows on a GPT disk, you may receive an error which reads “Windows cannot be installed to this GPT disk. The selected disk is of the GPT partition style.”What does this mean?
In fact, this error message indicates that the boot mode of your motherboard is set to Legacy BIOS. Hence, you can only install Windows to an MBR style disk. To remove this error message, you have two choices: convert GPT to MBR or change the boot mode to UEFI if possible.

How to Convert GPT Disk to MBR Disk

If there are multiple operating systems installed on the computer, you can boot your computer from that OS, and turn the GPT disk to MBR in Disk Management.
Right-click This PC and choose Manage -> Disk Management. Then in the disk map area, find the GPT disk and delete all partitions on it one by one through the “Delete Volume” feature until you get a blank disk. Now right-click the disk and choose “Convert to MBR Disk”. Now you can try to install Windows again.
However, if you do not have any operating system available to help you convert GPT to MBR, you have better use MiniTool Partition Wizard Bootable CD to help you. You can create a bootable media on a normally running computer and then use it to boot your computer.

Change Boot Mode to Install Windows to GPT

Today most motherboards support both Legacy BIOS boot mode and UEFI BIOS boot mode. If your mother board also support both boot methods, then you have the chance to install Windows on GPT disk. Please enter BIOS and set the boot mode to CSM boot or choose Both. Once the change has been made, please press on F10 to save changes, and then you can install Windows on a GPT disk.
