Hi Plutom. I'll try and explain it as clearly as I can - it's easier to do these things than explain them sometimes:)

1. Create your sphere - set it's attribute to Positive

2. Create the cyclinder - set it's attribute to Negative

3. Now ensure you have both objects selected (If you still have the cylinder selected press shift+left click on the sphere so that both are now selected).  

4. You will now see there is a 'G' in the little list next to the objects. This is the grouping icon. Click that and it will disapper as both objects are now grouped together. If you have placed your cylinder inside the sphere you should see a hole and the cylinder not visible when you render the scene. But you must make sure that the height of the cylinder is greater than the height of the sphere to see the hole (as you have done in your image above).

You can select cylinder on it's own from the pallete at the bottom of the screen, and when you move it around in range of the sphere you will see the boolean effect change depending on how much of the cylinder intersects with the sphere.

Don't forget the boolean effect will only be visible when you render the scene. You will not see it in any of the display modes.

I hope that helps:)
