I red again my post, I did not want to criticize in any way, I'm sorry if it
sound rude - however I think that the first item could be more explicative,
kind of "don't choose me, choose one in the list below" :-).

I split my answer in two parts.

First, as I wrote, there was no way to boot whichever entry I chose, and I got
no error - just a black screen in case of second entry.

Second, it looks like the last grub fixed the issue, I mean grub2
2.02~beta2-55.1.

I'm going to fresh net install the system, in order to clean up messy things
around. I'll be reporting back as soon as I've test booting from snapshot on
the fresh installed system.
