When installing Windows on a GPT disk, you may receive sầu Windows cannot be installed on GPT disk error:

"Windows cannot be installed lớn this disk. The selected disk is of the GPT partition style."

What causes this error?


This is mainly because the motherboard supports Legacy BIOS only rather than both Legacy and UEFI or CSM boot. Under legacy BIOS mode, you can only install Windows to lớn an MBR disk since traditional BIOS cannot recognize GPT partition, but data read/write on GPT disk is available as long as Windows supports it.


To fix this error, firstly you need lớn enter BIOS Setup khổng lồ see what the boot mode it is set to lớn. Start/restart computer and continuously press a key lớn enter BIOS before the Windows biểu tượng logo appears. Different computers may require different keys, so you had better search "how to lớn enter BIOS plus computer trademark or motherboard name" on the internet to find the exact key.

In BIOS, if you find no signal showing you are using a UEFI motherboard lượt thích the following picture shows, maybe you are using a traditional motherboard which supports legacy BIOS boot only. Under this situation, the only solution is lớn convert the GPT disk lớn an MBR disk.


Here are the deals:

Solution 1. Convert GPT Disk to lớn MBR if the Motherboard Supports Legacy BIOS Only
Note: We will explain 3 ways to lớn convert GPT disk lớn MBR disk. The 2nd & 3rd ways will cause data loss since Windows requires you to delete all partitions.

1) Use Partition Wizard

It is possible khổng lồ make the conversion during the installation process. Please vì the following:

Step 1: gọi out CMD.

Once the error pops up, cliông chồng "OK" lớn cthất bại the error và try pressing on "Shift + F10" to lớn Call out CMD. If the utility does not emerge, please go bachồng lớn the install Windows interface, then press "Shift + F10" again khổng lồ launch CMD.


Step 2: clean the disk và convert it to MBR.

Now you need to do a clean on the disk by typing the following commands:

"diskpart -> list disk -> select disk 1 (1 signifies the number of GPT disk) -> clean -> convert MBR."


When diskpart shows it has successfully converted the selected disk lớn MBR format, you can exit from this program and continue khổng lồ install Windows.

3) Use Disk Management Utility

If another Windows OS is available on the same computer, then Disk Management utility is helpful. Try these operations:

Step 1: go to Disk Management.

Start the working Windows & enter the built-in Disk Management tool by right clicking the "Computer" ibé on the desktop, choosing "Manage", and selecting "Disk Management".

Step 2: delete volume.

Delete all partitions or volumes on the GPT disk one by one via the right-cliông xã function "Delete Volume".


Step 3: convert to MBR disk.

When the entire disk becomes an unallocated space, right cliông xã the GPT disk và choose "Convert to lớn MBR Disk". After these steps, the original GPT disk will be converted to an MBR disk, & then you can go on installing Windows on this disk.


Tip: When deleting volumes you may meet the situation where some special volumes lượt thích system volume, recovery volume, & OEM volume cannot be deleted. For reasons và corresponding solutions, please see Cannot Delete Volumes in Windows.

Solution 2. Change Boot Mode If the Motherboard Supports Both Legacy và UEFI Boot

Currently, most motherboards support both the Legacy boot & UEFI boot, and users can choose the most appropriate one manually. If you select Legacy only, it will be impossible to lớn install Windows on GPT disk. At this time, you can enter BIOS và phối the boot mode khổng lồ CSM boot or choose Both.

Once the change has been made, please press on F10 to lớn save sầu changes, và then you can install Windows on a GPT disk.

Error 2: Windows Cannot Be Installed to This disk. The Selected Disk Has an MBR Partition Table.

When installing Windows 7, Windows 8 or other newly released Windows OS, you may receive sầu another error saying Windows cannot be installed on MBR disk:

"Windows cannot be installed on this disk. The selected disk has an MBR partition table. On EFI systems, Windows can only installed on GPT disks".

Why can"t Windows be installed on an MBR disk under EFI systems?


To answer this question, you need khổng lồ know something about UEFI + GPT boot. Under EFI systems, theoretically both an MBR disk and GPT disk can be used lớn boot operating systems, but Microsoft rules Windows can only be installed on a GPT disk. To fix this error, the best way is to convert the MBR disk lớn a GPT disk.


Convert MBR Disk to GPT Disk to Fix the Error

Steps are nearly the same as those to lớn convert GPT disk lớn MBR disk, và the only difference is that you need to lớn convert disk to lớn GPT rather than MBR. For converting without data loss, please see Convert MBR Disk to GPT Disk for more details.

That"s not all…In the former part, we have sầu said most UEFI motherboards tư vấn both Legacy boot and UEFI boot but we can change it manually. If the error is caused by setting boot mode to be UEFI only, changing the mode to lớn Both or CSM boot may fix the error, which has been introduced in Error 1.

"You can perform a fresh Windows installation on a dynamic volume only if that volume was converted from a basic volume and retained an entry in the partition table. Simple volumes converted from basic disks vì not have an entry in the partition table unless they were system or boot volumes prior khổng lồ conversion."

Convert Dynamic Disk khổng lồ Basic Disk khổng lồ Solve the Problem

Error 4: Windows Cannot Be Installed lớn This Disk. This Computer"s Hardware May not Support Booting lớn This Disk.

Another error message you may receive during Windows installation is:

"Windows cannot be installed lớn this disk. This computer"s hardware may not support booting lớn this disk. Ensure the disk"s controller is enabled in the computer"s BIOS thực đơn."


Generally speaking, there are 2 possible reasons:

Hard disk protection is enabled.


Solution 1. Remove Hard Disk Protection

For the first situation, please read the specification or contact a sales person lớn confirm whether there is hard disk protection if the computer is not configured by ourselves. If there is, remove the protection by following the instructions.

Solution 2. Change SATA Controller Mode

Different BIOS gives different options khổng lồ set itself to factory settings, lượt thích Restore Defaults, Load BIOS Defaults, and Load Optimal Defaults, so you should choose the correct one according to lớn practical situations.

However, when this solution does not work, you must change the hard disk mode manually in BIOS. If the current state is IDE, change it khổng lồ AHCI. If the current mode is AHCI, change it to lớn IDE, etc. Actually, if Compatibility or Compatible is given, you must choose this mode.

Moreover, when you are installing the Data Center or Enterprise Server edition of Windows Server 2008/R2 or later to a raw disk via CD or DVD, you may get the same error. This is because the mặc định SAN policy during thiết lập on new installations of Data Center or Enterprise SKUs is Offline Shared, which applies Offline and Read Only attributes to lớn any presented disks that are on a shared bus & not considered as System or Boot disks.

RAW disks cannot be detected as System or Boot, leading to offline và read only attributes. As a result, you cannot install Windows to these kinds of disks.

When this error appears, it indicates there may be something wrong with the hard disk.


Backup & Repair/Replace the Hard drive

At this time, you must stop Windows installation, and then backup important data immediately in case of a real disk failure. If there is not so much data that is required lớn back up, just copy and paste them lớn a safe place. However, if you want lớn backup all or a large number of data on the disk, using a third các buổi party disk clone software to lớn bachồng up the entire hard disk can save you a lot of time.

Tip: If there is no Windows to use, you may need a bootable disk clone tool, và không lấy phí MiniTool Partition Wizard Bootable CD might be a good choice.

When the backup is made, check the health state of the disk by running a diagnosis & repair tools which can be downloaded either from the hard disk manufacturer’s website or from a professional downloading center. If Windows won’t boot, please download the ISO tệp tin và burn it khổng lồ a CD or DVD on another computer, và then make a disk diagnosis via the bootable disc.

If errors are detected from your hard disk but cannot be repaired, replace the dying hard disk with a new one. However, if it is under warranty, send it back to the manufacturers because they will repair the disk or give you a new one.
