Dual Booting LL 2.0 with other Ubuntu (14.04) based distros

m654321,

Thanks for the detailed response.  This should be an easy fix!  However, now that I see how thorough you are, I'm worried that you may not have made some minor error before and the problem is more difficult than I first thought.  We'll soon find out.  Follow steps below and everything should end up working.  If it doesn't then we've got a more difficult problem than I thought.

*  Boot computer with live Linux Lite DVD (not Zorin DVD)

*  When up and running, open a terminal

*  Mount the LL2 root partition on the HDD to the live environment

Code:

sudo mount /dev/sda2 /mnt

*  Install grub to the MBR of sda drive

Code:

sudo grub-install --boot-directory=/mnt/boot /dev/sda

*  Unmount the LL2 root partition

Code:

sudo umount /dev/sda2

*  Close terminal, shutdown live DVD and remove from tray.

*  Boot computer normally again and you should have LL2 grub menu show up with LL2 being first (default) choice and Zorin further down list.  (LL2 is now in charge of booting the computer.)  It's possible that it may either boot straight into LL2 without giving boot menu, or show boot menu without Zorin on it.  If either of those two things happens, then let computer boot into LL2, open a terminal and run command to update grub.  That should add Zorin to menu and cause grub menu to show on next reboot.

Code:

sudo update-grub

Let us know if this worked.
