Once you are in live usb try the following comments

sudo -i
apt-get update
apt-get install lvm2

{IF FILE SYSTEM IS ENCRYPTED => DECRYPT}

vgscan --mknodes                        *##not down the volume name##*
mount /dev/<volume-name>/root /mnt      *## For me 'ubuntu-vg' ##*
mount /dev/sda1 /mnt/boot               *## fdisk -l for right sd--##*

mount --bind /dev /mnt/dev 
mount --bind /dev/pts /mnt/dev/pts
mount --bind /proc /mnt/proc
mount --bind /sys /mnt/sys

cp /etc/resolv.conf /mnt/etc/resolv.conf
chroot /mnt

apt-get update    
sudo apt-get install linux-generic
update-grub 
apt-get clean
umount /mnt
reboot

[DECRYPT] If the file system is encrypted then decrypt 

apt-get install cryptsetup
modprobe dm-crypt
cryptsetup luksOpen /dev/sda1 crypt1  *## fdisk -l to get right sd--##*
*##Write the passphrase##*
