grub menu isn't showing up at boot

i have manjaro kde dual booted with win 10 on lenovo ip 330.

but Everytime I boot it goes into windows

I tried the following but nothing worked:

  1. holding / pressing 'shift'
  2. holding / pressing 'esc'
  3. changing to legacy mode
  4. turning on/off fast boot

I can see the partition where I installed manjaro but can't find manjaro when I try to change boot order from bios
