Disk utility and other options in menu bar while installing is still not visible, but I can manage this with my old El Capitan USB installer.
Anyway, I can finally manage and get work Sierra, but...
I can boot to Sierra only with flag -f
When I try to boot without it, it hangs on this:

this is output with verbose flag:

any suggestion?
thanks
