This was how my belt was put on by previous owner this causes the car to overheat in just minutes and also some very violent reverse boiling to the top radiator hose exactly as you described.

I replaced the thermostat I have replaced, the water pump, radiator seems to be flowing and coolant kicking in, but when I drive it and then check the hoses the lower radiator hose is not filled with water. Also, when I release the radiator cap or the reservoir tank cap no pressure seems to be there. So what would the problem be in my overheating problem?

It sounds like the radiator is plugged, there should be coolant in both hoses. The other item could be that the thermostat you installed is not opening. I would try a pressure test first, just to rule out a leak internally. Then test the new thermostat and radiator.
