How to reboot Windows 8/10 and go to Advanced Boot options with WinAPI?

I know that one can reboot a workstation using InitiateShutdown API. I'm curious how to do I reboot and go to "Advanced Boot" option window that is available on Windows 8/10? (I'm asking about WinAPI or a registry setting.)

enter image description here

PS. The same can be achieved by calling:

shutdown \r \o

For Windows 8 and up you can use the undocumented dwShutdownFlags value 0x400 that will initiate reboot and then show advanced boot menu options. That flag can be combined with SHUTDOWN_RESTART, SHUTDOWN_RESTARTAPPS, SHUTDOWN_FORCE_OTHERS, SHUTDOWN_FORCE_SELF.

As such:

DWORD dwResult = InitiateShutdown(NULL, NULL, 
    30,                                            //Use 30-second timeout 
    SHUTDOWN_RESTART | 0x400,                      //Reboot with advanced menu options
    SHTDN_REASON_FLAG_PLANNED | 
    SHTDN_REASON_MAJOR_APPLICATION |
    SHTDN_REASON_MINOR_OTHER);

Keep in mind though that this flag is undocumented, so use it at your own risk!
