I am trying to repair my GRUB using [those](https://forums.kali.org/showthread.php?20559-How-To-Repair-Kali-Linux-Grub-With-Kali-Linux-Live-Cd-Dual-Boot-With-Windows-7) instructions:

```
mount /dev/sda3 /mnt
mount --bind /dev /mnt/dev
mount --bind /dev/pts /mnt/dev/pts
mount --bind /proc /mnt/proc
mount --bind /sys /mnt/sys
chroot /mnt
grub-install /dev/sda
update-grub
exit
umount /mnt/dev/pts
umount /mnt/dev
umount /mnt/proc
umount /mnt/sys
umount /mnt

```

but when I need to do the `update-grub` command, it says `command not found`, so I tried to do `apt-get update` in order to install grub (`apt-get install grub`) but I only get this output:

> 
> Reading package lists... Done
>

And nothing seems to be updated.

So I started another terminal, and updated before using the `chroot` command, and it works (packets were downloaded).

Then, I installed GRUB, then tried to do the `update-grub` command after the `chroot` command, but again I get:

> 
> command not found 
>

I see that there is problem with the **chroot** command and the installation of new packages, but I did not find any solution yet... Any idea ?

Thank you

p.s: here is the content of the /etc/fsab file of the kali partition:

```
