No, the problem appeared after a major update of Windows.
I used dual boot since Windows 2000, first with LILO as boot loader and later with GRUB.
I don't remember a time when i can't restore boot loader after that Windows broke it (e.g. after a Windows re-installation).
This time seems that...
Thank you. I tried to execute the command but unfortunately it can't help me. This is the response:

Couldn't find valid filesystem superblock.
Hi, after a few days I managed to do some tests with testdisk.

mount: /mnt/disk: wrong fs type, bad option, bad superblock on /dev/sda6, missing codepage or helper program, or other error.
and fsck also can do nothing:
> fsck...
Thank you for your reply.
I'm not sure I understand the meaning of your command, but this is the output:
sudo chroot /usr/sbin/update-grub
chroot: cannot change root directory to '/usr/sbin/update-grub': Not a directory
I would like to launch update-grub after setting root in /dev/sda6...

After a Windows update, i can't start Ubuntu, Grub starts in command-line mode.
I start pc with a live version of Ubuntu and these are my attempts:
fdisk -l /dev/sda
