Windows 10 pops up Windows Boot Manager on startup

After an update, Windows Boot Manager appears on boot. I have to press Esc to enter BIOS and then Esc again to boot into Windows. The hard drive and system are fine. How do I stop it from showing up at startup?

    Restart your computer and enter BIOS/UEFI settings (usually by pressing Del, F2, F10, or Esc during startup).

    The update might have altered your boot configuration data (BCD), causing Windows Boot Manager to become the default boot option.

    boot-manager usually pops up if there are more than one OS installed!

    Within BIOS, you can tell it: Which hard drive the computer should us for booting.

     

    ### If you only run one OS, you can disable the menu entirely:

     

    • Press ```Win + R```, type ```sysdm.cpl```, Enter.
    • Go to Advanced > Startup and Recovery > Settings.
    • Uncheck Time to display list of operating systems.

     

    ### Use System Configuration (msconfig)

    • Press ```Win + R```, type ```msconfig```, and hit Enter.
    • Go to the Boot tab.
    • Select the OS you actually use.
    • Click Set as default.
    • Adjust Timeout (e.g., set to 0 or 3 seconds).
