Best way to create real loading screen???

Use the built in level streaming so that you can remove the loading screen when you want and use built in load/unload.

I would make heavy changes, but this is a base.

Thanks for your answers guys!!
I saw this one but I was thinking, will the loading screen last until all shaders are fully loaded? Is there any way to know when the shaders are fully loaded? Thanks
