Reinstallation of GRUB fails

  • 772

I have installed W7 as a second OS with dual boot on my notebook which was already running Ubuntu 14.10.
W7 was installed on the HDD. For Ubuntu the /home and /usr/share are installed on the HDD and the rest is installed on the the additional SSD. After the installation of W7 the grub boot menu was deleted so I tried to reinstall it with a live CD.

I run boot-repair and selected Recommended repair which then gave me a prompt saying:

 apt-error detected. Please open a terminal then type (or copy-paste) the following command:
 sudo chroot "/mnt/boot-sav/sdb2" apt-get -f install

But when I run this command I get:

  debconf: Perl may be unconfigured (Can't locate strict.pm in @INC (you may need to install the strict module) (@INC contains: /etc/perl /usr/local/lib/x86_64-linux-gnu/perl/5.20.1 /usr/local/share/perl/5.20.1 /usr/lib/x86_64-linux-gnu/perl5/5.20 /usr/share/perl5 /usr/lib/x86_64-linux-gnu/perl/5.20 /usr/share/perl/5.20 /usr/local/lib/site_perl .) at (eval 1) line 2.

I tried to run sudo apt-get install -f and sudo apt-get autoremove but didn't help...

  1. Ok I finally found a solution: Since the /home, /usr/share and the rest are on different partitions I needed to mount everything correctly:

    sudo mount /dev/sdb2 /mnt
sudo mount /dev/sda4 /mnt/usr/share
sudo mount /dev/sda3 /mnt/home
for i in /dev /dev/pts /proc /sys /run ; do sudo mount -B $i /mnt$i ; done
sudo mount -o bind /etc/resolv.conf /mnt/etc/resolv.conf 
sudo chroot /mnt /bin/bash
[Optional -> was needed in my case] sudo apt-get install grub-pc
grub-install /dev/sda
sudo update-grub

    And everything worked again!
