How do I Locate which drive my OS is on, and change it to the C: drive if it's not on there already?

recently reinstalled windows 11 to my Dell G5 15 laptop. It now uses almost 100% of my HDD, (I already used chkdsk to try and resolve this issue). It also seems to have reassigned my D drive as my OS drive, and my C drive as my data drive. But for some reason still thinks the OS is on the C drive? When I try to reformate the C drive it tells me the OS is there.

this is what happens when I try to format the C: drive

    Hi, I am Dave, I will help you with this.

    Right click your Start Button and open Disk Management

    Expand the bottom pane in Disk Management so all drives are visible in that pane.

    Please provide a screenshot of that Disk Management window.

    Sorry, I was offline.

    Your system seems to be booting to the C drive, but it seems Windows was originally installed on the other drive, and the boot partition and recovery partition is on the other drive.

    Did you re-install Windows on that PC and if so, which drive is the new installation on is that the top or bottom drive?

    Without any doubt your powered-on machine aka running Windows is Disk 0 partition 1, Drive C, "DATA", capacity "Boot".
