Windows cannot be installed to this disk GPT
There are many discussions about the error that “Windows cannot be installed to this disk. The Selected Disk is of the GPT Partition Style”. Here are some cases:
I'm trying to install Windows 7 on a separate 100GB partition beside my Windows 8 partition (dual boot). The disc boots fine, but I can't select my partition (Disk 0 part 5) because of the error: "The selected disk is of the GPT partition style".
I tried to install Windows 10 on my partition. When I select the partition, I got the error message: "Windows cannot be installed on this disk. The selected disk is of the GPT partition style".
While trying to Wipe Windows 7 and install Windows 8 on my Zenbook, I have encountered an annoying error message: "Windows cannot be installed to this disk. The selected disk is of the GPT partition style". No other information is given.
Why “the select disk is of the GPT partition style” happened?
To figure out the problem of “Windows cannot be installed to the disk. The select disk is of the GPT partition style”, you need to know about GPT partition style and MBR partition style first.
MBR and GPT are two different partition styles. MBR is the abbreviation of master bootable record, and it only supports the maximum capacity with 2TB, up to four primary partitions, or three primary partitions plus one extended partition. Most of personal computer’s motherboard only supports BIOS and it is installed with MBR, so, for many users, they always install windows system on the MBR disk.
GPT is abbreviation of GUID partition table. It is a part of EFI, which is port between operating system and platform firmware. GPT can make use of a very large space that is more than 2TB limit of MBR disks. GPT disks allow an almost unlimited number of partitions. Each GPT partition has a unique identification GUID and a partition content type. And you can have more primary partitions. However, the Windows implementation restricts this to 128 partitions.

Thus, if your computer is set up to boot in legacy BIOS mode, while the hard drive you are installing Windows is partitioned as GPT partition style, the error “Windows cannot be installed to this disk. The selected disk is of GPT partition style” would happen.
How to fix “The select disk is of GPT partition style” error?
After knowing MBR partition style and GPT partition style, and why the error happened, here we provides two different ways to solve the problem: you can change Legacy BIOS mode to EIF/UEFI mode or convert GPT partition style to MBR partition style to settle the problem.
1. Change boot mode from Legacy BIOS to EFI/UEFI
Step 1. Completely shut down your computer.
Step 2. Power on the system. As soon as the first logo screen appears, immediately press a special key (usually F2, F8, F12, DEL) to enter the BIOS.
Step 3. Use the arrow keys to select "Boot" option.
Step 4. With Boot Mode highlighted, press "Enter", and then use the down arrow to select "EFI/UEFI mode" and press "Enter".
Step 5. Press "F10", and select "Yes" to save the change and exit the BIOS.
2. Convert partition style from GPT to MBR via Diskpart
You can use Windows Diskpart to convert GPT disk to MBR disk. Follow the steps below:
Enter system installing interface by using Win installation disc or bootable USB drive. and then press “Shift”+”F10” to open the command prompt.
Input “Diskpart” (do not input quotation mark, the following as well), and then press “Enter” to enter operating interface.
Input “list disk”: to check hard disk properties. Pay more attention to capacity of hard disk to select.
Input “select disk 0”: to select disk 0 as the disk that is operating.
Input “clean”: to clean up current hard disk’s partition.
Input “convert mbr”: to convert GPT into MBR.
Input “create partition primary size = xxx”: to create the size of primary partition.
Input “format fs = ntfs quick”: to format disk to NTFS quickly.
Input “exit”: to finish operating.
Input “exit”: to shut down the command prompt.
After converting GPT to MBR, you can shut down the command prompt and install windows system on computer in normal way. However, this method would clean all data on the GPT disk, and you cannot cancel the process. Thus, you need to backup hard drive before converting, or you can try a third party software like AOMEI Partition Assistant to convert from GPT to MBR without data loss.
3. Convert GPT partition style to MBR partition style with AOMEI Partition Assistant
AOMEI Partition Assistant is a great hard disk partition manager that allows you to convert GPT partition style to MBR partition style without losing data.
Free download to try AOMEI Partition Assistant Professional. Windows 10/8/7/Vista/XP is supported. Windows Server users should turn to AOMEI Partition Assistant Server edition.
Step 1. Install, and launch AOMEI Partition Assistant. Select the GPT disk that needs to be converted, right-click it and select “Convert to MBR Disk”.
Step 2. Click “OK” in the pop-up window.
Step 3. Back to the main menu, we can see the pending operations and click “Apply” to commit the changes.
Wasn't this process a piece of cake? After converting GPT partition style to MBR partition style, the error “Windows cannot be installed to this disk. The select disk is of partition style” would be fixed immediately.
AOMEI Partition Assistant is a powerful disk converter, you can also use it to convert MBR disk to GPT disk without data loss. It is a powerful partition converter, you can use it to optimize your partition easily, such as convert primary to logical partition, convert FAT/FAT 32 to NTFS, migrate OS to SDD and so on. you can even make a portable Windows 7/8/10 by using the function of “Windows To Go Creator”. What’s a powerful disk partition converter it is !
