Update Errors, also on fix commands!

Sure,

  1. First I tried to see my old and new HDD
sudo debconf-show grub-pc | grep -wi install_devices | awk -F: '{print $2}

but I only got the old one

 /dev/disk/by-id/ata-OCZ_VERTEX_PLUS_19JE1KI41W61AY8PEP3Y
  1. Then I checked the new HDD by listing
$ cd  /dev/disk/by-id/
/dev/disk/by-id$ ls
ata-ST9250315AS_6VC0JAYW
  1. Then I changed it to the new one
echo grub-pc grub-pc/install_devices multiselect /dev/disk/by-id/ata-ST9250315AS_6VC0JAYW | sudo debconf-set-selections
$ sudo DEBIAN_FRONTEND=text dpkg --configure -a

gave just a new line (did this after the above…)
