To check if you have duplicate installations of Windows 11 on your PC, you can follow these steps:

1. Check Installed Operating Systems:
   • Open the Command Prompt as an administrator. You can do this by searching for "cmd" in the Start menu, right-clicking on it, and selecting "Run as administrator."
   • Type the following command and press Enter:

          bcdedit
     

   • This command will display the boot configuration data and list all installed operating systems. Look for entries labeled as Windows 11.
2. Disk Management:
   • Right-click on the Start button and select Disk Management.
   • In Disk Management, you can see all your partitions. If you see multiple partitions with Windows installations, it may indicate duplicate installations.
3. Remove Duplicate Installation:
   • If you confirm that there are duplicate installations, you can remove the unwanted one using the Command Prompt. Use the bcdedit command to delete the entry for the duplicate OS. For example:

          bcdedit /delete {identifier}
     

   • Replace {identifier} with the identifier of the duplicate OS you want to remove, which you can find from the bcdedit output.
4. Caution:
   • Be careful when deleting entries, as removing the wrong one can make your system unbootable. Always ensure you have backups of important data before making changes to your system configuration.

If you are unsure about any steps, consider seeking professional assistance to avoid potential issues with your system.
