I am trying to install win10 from usb, but the monitor says "no signal" while in boot menu. The monitor works just fine after the win sign in appeares. What should I do?

What ports does your monitor have? I'd try a different port on your dedicated GPU first. If that doesn't work you can just disconnect the dedicated GPU from your system and plug your video cable directly into the motherboard.

Is this an external monitor connected to a laptop? Or is it a desktop? You should still be able to press the key to boot into the BIOS, which you will probably need to do to change your boot order so you can boot from USB.

It is a desktop, and yes I am probably in the boot menu, but the screen in black and says "no signal", so I can't see anything, only if windows login screen appears the monitor starts working again.

Unfortunately there is no hdmi port on the monitor, and I'm not entirely sure where to set which gpu do I want for the monitor to use.
