• Re-install Grub2 from DVD Rescue

    Boot the Rescue from the DVD. This should be the same Arch as the installation: ie; 32 bit or 64 bit..


    Once the DVD rescue gets to 'login', type: root
    from there I run fdisk -l to confirm my HD partitition order.
    We need to mount root (for me that's sda3)

    Now mount / (sda3) with:
    Code:
    mount /dev/sda3 /mnt
    To mount the other devices
    Next do:
    Code:
    mount --bind /dev /mnt/dev
    Then chroot:
    Code:
    chroot /mnt
    Code:
    mount /proc
    Code:
    mount /sys
    Your prompt changes to: Rescue:/>
    Here type:
    Code:
    grub2-mkconfig -o /boot/grub2/grub.cfg
    Code:
    grub2-install /dev/sda
    You can see it all here: https://dl.dropbox.com/u/10573557/Gr...ect/rescue.jpg

    'exit'
    # reboot

    If you use LVM please check this post: https://forums.opensuse.org/vbcms-comments/478290-article-re-install-grub2-dvd-rescue-3.html#post2519005

    N.B: This method should also work from a live cd
    This should be the same Arch as the installation: ie; 32 bit or 64 bit..USE LIVE CD TO RESCUE

      Any idea what I should do ?
      I'm on Leap 42.2 and use a separated boot partition on which Manjaro has seemingly overtaken GRUB for himself (if that makes sense)
      That is for older versions.

      Instead, after mounting your device to /mnt (ie: mount /dev/sdXN /mnt), you want to:
      Code:
      mount --bind /dev /mnt/dev
      chroot /mnt
      ... and, instead of the mounts for proc & sys in those versions, do:
      Code:
      mount -t proc proc /proc
      mount -t sysfs sysfs /sys
      That change has been in effect since v13.1
