Cannot reinstall OSX Mac mini 6,1 I've been trying to install Ubuntu server on my Mac mini 6,1 with no success.
However now I'm stuck and can't even reinstall OSX from a USB key. I've created it on my MBPr, and tested it there : it works fine.

Now when I try to boot from it in the Mac mini, I get a grey crossed-circle and the Mac mini shuts down.

Does anybody knows a way to fix that ?
Thanks
You can hold down the keys [cmd] + [r] while the mini is shut down and then push the power button. This should lead you to the recovery via the Mac App Store.
