How to Determine if a Disk Uses GPT or MBR.
Method 1
1) Use the Disk Management Tool
To access it, right-click the Start menu or press Windows Key+X and select “Disk Management.” You can also press Windows Key+R to open the Run dialog, type “diskmgmt.msc” into the box, and press Enter.
Locate the disk you want to check in the Disk Management window. Right-click it and select “Properties.”
Click over to the “Volumes” tab. To the right of “Partition style,” you’ll see either “Master Boot Record (MBR)” or “GUID Partition Table (GPT),” depending on which the disk is using.
Method 2
2) Use the Command Prompt or PowerShell
Launch a Command Prompt window as Administrator by right-clicking the Start button or pressing Windows Key+X and selecting “Command Prompt (Admin)” or "PowerShell". You can also locate the Command Prompt shortcut in the Start menu, right-click it, and select “Run as Administrator” or use "Search" and type "cmd".
Type the following 2 commands, pressing Enter after each one:
diskpart
list disk
You’ll see a table listing your connected disks. If a disk is GPT, it will have an asterisk (that’s a * character) under the “Gpt” column. If it’s an MBR disk, it will be blank under the Gpt column.
