I want to choose the layout the game will begin with, how can I do ?
You can't sorry. Its probably best to just remake it in the right order.

ok ...
but why ? is this so complicated to add this feature to Construct ?
No one before me asked this question ?

You can click and drag the layouts in the project tab. Just drag the layout you want to start first to the top of the list. The first layout in the list always plays first.
I tried it with 98.9 but it didn't work.
Let's re-test that !
EDIT : It works ! Thank you linkman !
