Fedora not boot on MacBook Pro

Dracut initqueque timeout and Dracut Emergency Shell

Fedora 25 - Dracut emergency console

If you, like me, are in troubles installing from an USB key the new Fedora 25 on a old MacBook Pro or on a complicated PC and you’re getting a dracut emergency console, take a breath because it’s a really simple case.
