How to reinstall windows when I cant load windows setup?

BTW it sounds like you've lost your boot partition

@jimfixer can u help me with that?

because nothing works for me, i mean i can't load windows setup (black screen with mouse cursor) i can't turn on computer (same black screen) for me doesn't work f8 or other f buttons and i can't turn on advanced start-up option menu for safe mode or for system recovery i even tried to make bootable recovery dick from another pc but even that doesn't work..

@pauliusam do you get a statues screen with system specs or by black screen do you mean you have nothing from the time you press the power button. Do you get a n opportunity to get into the boot menu? Could you also give me the model number of your Asus laptop. And are you able to get into the bios

@jimfixer yes im able to get it bios settings.
