Hi
Yes, I tried a manual installation, but failed because I don't have the necessary knowledge to do so ... unfortunately! Have now tried to install Solus Linux on the same system, worked immediately! Now I'm wondering what makes Zorin different that my machine can't digest? It's a shame because Zorin OS would have been my first choice for my switch from Windows.
Nevertheless, thank you very much for your effort! And if we can think of anything else to get Zorin running I'm totally open to it.
