A very *#BIG THANK YOU#* for all the great help, the research and the solution. I myself am back in "normal mode" :)
You're welcome!
What is the most reasonable setup here: GPT without any hybrid magic and ext4 because it is so common?
I would go with MBR and a single ext4 partition. GPT is fine too, but for a 1TB disk with a single partition it has absolutely zero advantage over MBR. andrea
