how to check if disk is mbr or gpt

There are multiple methods to check if a disk is MBR (Master Boot Record) or GPT (GUID Partition Table) on a Windows system:

1. Using Disk Management:
   • Right-click the Start button and select "Disk Management."
   • Right-click the disk you want to check (e.g., Disk 0) on the left panel.
   • Select "Properties."
   • Open the "Volumes" tab.
   • Look for "Partition style," which will state either "Master Boot Record (MBR)" or "GUID Partition Table (GPT)."
2. Using Command Prompt:

   • Open Command Prompt as administrator.

   • Type the following commands:

     diskpart
     list disk
     select disk X (replace X with the disk number)
     list disk
     

   • Check the "Gpt" column in the output. An asterisk (*) indicates GPT; absence means MBR.

3. Using PowerShell:

   • Open PowerShell as administrator.

   • Run the command:

     Get-Disk | Format-Table -AutoSize
     

   • Check the "PartitionStyle" column for either "GPT" or "MBR."

These methods allow checking the disk partition style visually or via command line depending on your preference and expertise.
