    Unable to boot from system partition


    Hello,
    I am unable to move my boot data to another partition. Please have a look at the following picture-:

    As you can see I have created a separate a partition before my C drive and formatted it.

    I have used the following command to copy the boot data from my C drive to the System partition(S:)

    bcdboot C:\Windows /s S: /f BIOS

    But as you can see C drive is still marked as "System" which means my PC isn't actually booting from drive S:.

    How do I force my system to boot from drive S: and not drive C: ???

    Thanks.

    Seems I solved this myself. Right click on the partition that has the boot data and set it as an "Active Partition".
