Hello everybody, I am new at UE4 (just downloaded it yesterday). I started the tutorials, but i am struggling at something that should have been very simple according to this step : https://docs.unrealengine.com/latest/INT/Engine/QuickStart/3/index.html
When i select the asset : “level” into “add new” in the content browser of unreal, it directly asks me to put a name to the level, and no “new level” dialog box opens like in the tutorial.
I tryed to right click the level that edit it but i end up in a black world with nothing into it.
Thank you if you take the time to answer me.
After “Add new” in content browser, you can create a new level, rename it in content browser, and double click it, to save and activate. You will see a black empty level.
Dialog box “New Level” you can find in menu “File” → “New Level…” or hotkey Ctrl+N
You can toggle between levels in this dialog box
thank you for your answer 
It worked perfectly, that was quiet simple as i taught
