Get disk number with PowerShell

Let's check which disk drives there are and which partition style they have. Let's look at how to get the disk number with PowerShell.

Run PowerShell as administrator. Run the Get-Disk cmdlet to get the disk number and information regarding the disks in the system.

              PS C:\> Get-Disk | Format-Table -AutoSize  Number Friendly Name       Serial Number                    HealthStatus OperationalStatus Total Size Partition Style ------ -------------       -------------                    ------------ ----------------- ---------- --------------- 0      VMware Virtual disk 6000c29a0f2feeebd0faf27ff2cc5d1b Healthy      Online                 60 GB GPT 1      VMware Virtual disk 6000c29ec4a86ded65e30426f3f9b4aa Healthy      Online                100 GB GPT

Convert GPT to MBR without data loss

There are so many tools out there. We know that and tried almost every one of them. However, you have to buy/register the software when you want to apply the changes.

We need a FREE tool that converts MBR to GPT that:

• Supports NTFS
• Supports REFS
• Support Windows
• Support Windows Server
• Will convert without data loss
• Not let us start the system in safe mode to convert
• Not let us reboot the system after the change

Is there a tool we don't have to pay for? We only want to convert from GPT to MBR, not more than that.

Important: Restart the system after converting the disk partition table style from MBR to GPT. This is to ensure that everything works as intended.
