Working normally from me, i get the Metro Bootloader when ticked, and do not get it when unticked.
Just added a Win 11 25H2 Enterprise, and tested with Win 11 24H2, and a Win 10 Iot LTSC on my Multi Booting System, All Works as it should.
Maybe a screenshot bbacle of your PC booting up (A Phone Photo Will do) and maybe a screenshot of your Easy BCD settings page
