Xbox does not start / takes a long time?

So, next Xbox problem 😅
Everything connected and turned on. Now we sit for half an hour in front of a green screen on the Xbox one is and nothing happens…
Normal on the first start?

No, that's not normal.
Mine needed something on the first start, but half an hour is too long.

The classic on / off have you already tried?

Otherwise turn to the support. They are usually quite fix, which concerns such problems.

Tried twice, without success.
The third attempt after superkompakte it worked. Let's see if after the updates finally everything works!
