    Ubuntu 14.04 'Unity' partition no grub

    My partition with Unity has lost it's grub, no matter what I do I cannot seem to get it back

    The partition is not showing at the boot menu, therefore cannot enter into it, tho can via Files (once in another os)

    Is there anyway I can fix this, without having to do a re-install

    I use the Grub Rescue CD. Works 9 times out of 10. You would have to download it and burn it to a CD. I am only reporting a method I use. There are probably other methods but I am just covering what I do. Once burned and booted it is pretty well self explanatory after that.

    You can boot from a live CD/USB, and chroot your / partition:

    Code:
    sudo mount /dev/sda1 /mnt
    sudo mount -o bind /dev /mnt/dev
    sudo mount -o bind /sys /mnt/dev
    sudo mount -o bind /proc /mnt/dev
    sudo chroot /mnt
    substitute the location of you / partition for /dev/sda1

    Once you have chrooted the partition try the following commands:

    Code:
    sudo grub-install /dev/sda
    
    sudo update-grub
    Note: If you are running a 64-bit version, you must use a 64-bit live CD/USB,

    came to the conclusion to be 'brutal' and did the very latest daily iso
