I recently installed an SSD hard drive for my Mac Mini, and all went fine until I tried to do a clean installation of High Sierra via USB.

I've downloaded the installer to USB memory stick by following the steps described in this tutorial: https://www.youtube.com/watch?v=BVkMvO60SAs That is, configuring the pen through Terminal, etc, etc ...

After several minutes of loading bars with apparent normality, finally it goes to a black screen with the apple and a load bar that never complete.

How can I proceed with the installation from here?
