Dual booting with windows 10

[torreydale]

Sounds like you have the Windows boot manager as your chooser as per Matthew Moore's tutorial.  Then you get the blue grub.  Whether Linux Lite boots to the gray screen with the feather or to the blue grub and then to the words Linux Lite with dots underneath, varies according to your graphics card.  This is normal behavior.  If you didn't select Linux Lite at the blue screen, it would count down a few seconds and select that automatically.
