Manjaro Advanced Settings Screen not showing on startup

Hi there,

I can not get to the Manjaro Advanced Settings screen to switch kernels,

I tried pressing F8, esc, shift and still no effect.

What can I do?

you can change and get Grub on start

I did what you have recommended but still have no Grub menu.

I also tried to push esc, F8 and shift separately after changing grub timeout style to menu,

Anything else I may try?
