ByWhen we install a new hard drive or SSD in Windows 10 or 11, it is very important to know whether the disk is GPT (GUID Partition Table) or MBR (Master Boot Record). This information is important for disk usage, boot mode, and operating system compatibility. In this article, we will explain in detail how you can check if your disk is GPT or MBR.
What is the difference between GPT and MBR?
GPT (GUID Partition Table) and MBR (Master Boot Record) are two types of disk partitioning schemes.
GPT is a modern technology that works with UEFI BIOS and supports drives larger than 2 TB.
MBR is the older system, which only supports drives up to 2TB and up to 4 partitions.
How to Check Disk Partition Style – 5 Easy Ways
1. Check via Disk Management
Disk Management is an in-built tool of Windows that provides information about drives and partitions.
Steps:
1. Press Windows + X and select “Disk Management”.
2. Right-click on the disk for which you need information and click “Properties”.
3. Go to the “Volumes” tab.
4. In front of “Partition style” it will be written – GPT or MBR.
This is the easiest and graphical method.
2. Check Disk Partition Style via Command Prompt
If you are comfortable with the command line, then this method is fast and effective.
Steps:
1. Type “cmd” in the Start Menu and select Run as Administrator.
2. Type `diskpart` and press Enter.
3. Then type `list disk` and press Enter.
Now you will see a list of disks. If a disk has \asterisk in front of it in the GPT column, then it is GPT. If not, then it is MBR.
3. Find out GPT or MBR using PowerShell
PowerShell is another powerful tool that lets you get complete information about a disk.
Steps:
1. Type “PowerShell” in Start and click Run as Administrator.
2. Type:
“`powershell
Get-Disk
“`
This command will show a list of all disks. There is a column “Partition Style” that will tell whether the disk is GPT or MBR.
4. Windows Settings cannot find the Partition Style
Note that you can see the drives from Settings > System > Storage, but there is no information about GPT or MBR. So, Settings cannot be used to find out GPT/MBR.
5. Checking Disk Type using Third-Party Tools
If you are more comfortable with a GUI and want detailed information, you can use third-party software like:
MiniTool Partition Wizard
EaseUS Partition Master
AOMEI Partition Assistant
They identify GPT/MBR in just one click.
When to choose GPT and MBR?
Choose GPT when:
You are using UEFI BIOS.
The drive is larger than 2 TB.
You need more partitions (up to 128).
Choose MBR when:
Your system is based on Legacy BIOS.
The drive is smaller than 2 TB.
You only need 4 partitions.
How to Convert from MBR to GPT (Without Deleting Data)
Warning: Backup is required before converting to GPT.
You can use Windows’ mbr2gpt tool:
Steps:
1. Open cmd as Administrator.
2. Type:
“`cmd
mbr2gpt /convert /allowFullOS
“`
This command converts MBR to GPT without erasing data, but it only works if your machine is set to UEFI mode.
Convert MBR to GPT
If you need to convert GPT to MBR and don’t want to save data, follow these steps:
Steps:
1. Type `diskpart`.
2. Type `list disk`.
3. Type `select disk X` (where X is the number of your disk).
4. Type `clean` (this will completely clean the disk).
5. Type `convert mbr`.
Can both GPT and MBR exist together in a computer?
Yes, if you have more than one hard drive, then you can keep one in GPT and the other in MBR. There should be compatibility between the boot drive and BIOS mode.
Conclusion
Both GPT and MBR are used according to their respective needs. But it is very important to know what type of disk you have so that you can use it properly and avoid any kind of problem in the future.
In this article, we told you about the most accurate, easy, and efficient ways to identify GPT and MBR in Windows 10/11. Now you can easily check whether your disk is GPT or MBR and can also use or convert it as per your requirement.

Frequently Asked Questions (FAQ): Answers to common queries related to GPT and MBR
Q. 1: Is GPT disk better than MBR?
A. Yes, technically, GPT is more modern and secure. It supports larger drive sizes and allows creating more partitions. It also has security features like CRC (Cyclic Redundancy Check).
Q. 2: Can I convert MBR to GPT without losing data?
A. Yes, using the `mbr2gpt` tool in Windows 10 and 11, you can convert MBR to GPT without erasing data, provided your system is running in UEFI mode.
Q. 3: How to install Windows on a GPT disk?
A. To install Windows on a GPT disk, your BIOS must be in UEFI mode. During installation, the drive has to be formatted and selected as GPT.
Q. 4: Can GPT and MBR disks be kept together in the computer?
A. Yes, if your computer has more than one hard disk, you can keep one disk in GPT and the other in MBR. Keep in mind that the boot drive must be compatible with BIOS mode.
Q. 5: Partition Style is not visible in Disk Management, what to do?
A. If Partition Style is not visible in Disk Management, make sure that you have selected the correct disk and gone to the Volumes tab. Apart from this, you can get the information by using `diskpart` or PowerShell.
Q. 6: Can Windows XP be installed on a GPT disk?
A. No, Windows XP does not support GPT disks. Only Windows 7 and later versions can be installed on a GPT disk, that too when the BIOS is in UEFI mode.
Q. 7: Will my data be deleted if I convert a disk to GPT?
A. If you convert to GPT using `diskpart`, then yes, all your data will be deleted. But if you use the `mbr2gpt` tool, the data is safe, provided all the conditions are met.
Q. 8: How to identify which system supports GPT and MBR?
A. Systems with UEFI BIOS support GPT and systems with Legacy BIOS support MBR. You can check which mode your system is in by going into the BIOS.
Q. Q. 9: Are GPT disks more secure from viruses?
A. GPT has some security features like CRC for data integrity, but the use of antivirus software is necessary to prevent viruses.
Q. 10: Can Linux be installed on a GPT disk?
A. Yes, most Linux distributions fully support GPT, especially when the system is in UEFI mode.
