Hi to all. I'm a new member, I used Ubuntu for a while and I wanted to try Kali.
I installed Kali in dual boot with W7, and I choosed for the KDE, but later I installed GNOME, and now I have a problem during boot.
In the GRUB I have this situation:

if I choose for the first entry, kali doesn't boot and I have to force shutdown (it remains on a black screen).

If I go in advanced options, I have this situation:

the first 2 entries doesn't boot, the 3th boot with GNOME.

In gparted I have this:

I tried to run
sudo apt-get update
sudo update-grub
, the second command is interesting:
root@Cosimo-G62Kali:~# sudo update-grub
Generazione file di configurazione GRUB...
