Can I convert mbr to gpt during Windows installation without data loss

To convert MBR (Master Boot Record) to GPT (GUID Partition Table) during a Windows installation, the built-in command prompt is the best tool to convert MBR to GPT during Windows 11 installation. Here are the steps: 

1. Insert the Windows installation USB or DVD and boot from it.

2. When you reach the "Windows Setup" screen, press Shift + F10 to open the Command Prompt.

3. Type diskpart and press Enter.

4. Type list disk and press Enter.

Identify the disk you want to convert. Disks will be listed as Disk 0, Disk 1, etc.

5. Type select disk X (replace X with the disk number) and press Enter.

6. Type clean and press Enter. Warning: This will delete all data on the disk.

7. Type convert gpt and press Enter.

8. Close the Command Prompt and continue with the installation process. The disk will now be recognized as GPT.

Please back up the data first if possible as this is a risky task. By following the steps listed above, you should be able to convert mbr to gpt during windows installation.
