macOS High Sierra Installation Fail I wanted to install High Sierra and made a USB Installation Disk with Disk Maker X

All goes well and the installation is doing fine.

Then this screen appears:




  OSX couldn't install on this computer. To enter the Apple Diagnostic program to test your hardware please hit D during reboot.


SO that's what I did.

Now holding D during reboot does exactly nothing but instead it goes to this screen:



And from this screen it then goes back to the former error.

And that's it. Nothing else is happening.

I can enter the Disk Utility when the error is appearing. But I can't Partition the HD nor delete it because it is used by another process.

Nice. Now what?
David Anderson was right. The Disk Maker X was the problem. The bootstick was corrupted apparently.

I created a boot Stick via Terminal

sudo /Applications/Install\ macOS\ High\ Sierra.app/Contents/Resources/createinstallmedia --volume /Volumes/MyVolume


The last time I did this a Bootable Stick wasn't as easy as one terminal command that's why I used this 3d party tool. Better keep away.

Thanks for the hint.
