    In case first see: Terminal QuickStart Guide.

  3. Possibly to Find the Volume to Fix (LVM or Ordinary Partition)

    sudo apt-get install lvm2

    So now Execute a Disk Scan to Find out existing Partitions:

    lvmdiskscan

    In the Output you should be able to Recognize your Device…

  4. Chrooting into Ubuntu System.

    1. Mounting the Root.

      sudo su
      mount /dev/[sdAX] /mnt/

      For Example:

      mount /dev/sda2 /mnt/

    2. Then Only if Boot is in a Separate Partition: Mounting the Boot

      mount /dev/[sdaY] /mnt/boot

    3. Mounting Proc,Dev & Sys.

      mount -t proc none /mnt/proc
      mount -o bind /dev /mnt/dev
      mount -t devpts none /mnt/dev/pts
      mount -o bind /sys /mnt/sys

    4. Chrooting.

      chroot /mnt/ /bin/bash

      Testing Network Connection:

      ping -c 3 google.com

      If No Network Connection then Try:

      exit
      cp /etc/resolv.conf /mnt/etc/resolv.conf

      And then Chroot Again!

      chroot /mnt/ /bin/bash
