My method is to close all the air valves etc.

I usually leave the 'highest' one open to allow the incoming water to push

You can't fill the system if the air valves are closed. As the system fills
you need to be bleeding each and every radiator.

Does the boiler have an automatic bleed valve on it - if so - it may have a
cap on it. The needs removing to allow it to work.
