When I first got my PC it was in the UEFI mode. I had it downgraded to Windows 7, then a while later I upgraded it to Windows 10. That put it in legacy mode, how can I change it back?

    you need to disable LaunchCSM or Legacy on BIOS but you will need to re-install windows 10 from scratch.
    if it's a desktop, press Del key on boot to enter BIOS.
    Please post your PC model too.
