Thanks again … 
Funny to know that last thing I was doing on pc before last shutdown was playing to Assassin’s Creed II after a stop of maybe 1yrs… 
Anyway…
this second attemp made some modify, but essentially the problem is still remain the same.
Normal Mode: failed with a reboot
Safe Mode: failed with a reboot but the last file this time is CLASSPNP.SYS
Here the second fixlog.
Thanks
Stefano
