MultiOS_3in1 (Android+Libreelec+Linux) install to eMMC

This sentence just means that at the end I should shutdown, right?:thinking:

I follow all steps (tooks more than 1 hour all steps) and now I’m in android and I don´t have any choice to go into Linux or Libreelec.
I already reboot several times but no way.
Have you any ideia what I’m missing here?:unamused:
Thanks.
