Q: My car is not starting

I am having issues with my bmw 5 series 530 xi 2005 model.. I woke up this morning to start the car which worked well. Went back in to freshen up to go out and ever since the car has refused to start.. All light and functions are working including the AC.. Each time I press the start button, the light on the dash board turns up, the fuel meter moves indicating the fuel guage and every other thing and I hear a double click in the bonnet which I think is the kick starter and a screwing noise from the back, don't know what's causing that and were the noise is coming from till I press to turn off and it all goes off.. But yet the car engine is not starting.

I've tried reaching for the kick starter, use a rod to hit to see if that will work, no it didn't.. Also tried jump starting the car from the bonnet, still same thing. I took out my car battery, tried another charged battery and still the engine didn't start. I have a mechanic here with me in the house but I need your help.

My car has 177389 miles.
My car has an automatic transmission.
