Hi, thanks for letting me participate in the forum.
Several days ago I am trying to make a triple boot with debian-windows10-batocera, but I can not configure the grub2 of debian to allow me to access batocera.
I add it manually and by grub customizer, and I can not get it to show it, and it does not start loading kernel error and it asks to specify the file system.
Everything is configured on a single disk and so I need it to be.
