No boot after Boot-Repair-Disk

[gold_finger]

Once they get the bootloader sorted out (I always put it in the MBR of the drive I'm booting from), ....

Just to clear up any possible confusion for fbr -- this is generally what happens during boot up:

• Push power button to turn computer on
  
• Code residing on motherboard carries out an initial check of components, then points to the MBR of hard drive to continue boot process.
  
• MBR of drive contains only initial files needed to continue booting, then points to somewhere on the disk where the rest of needed files are to finish booting into the OS.
  
• The rest of boot files will either be on a special boot partition, or on the root partition of the OS.
  

Both Boot-Repair (that you tried before) and method I outlined above install code to the MBR.  The difference is that Boot-Repair seems to have pointed from the MBR to the root partition of a different distro to finish booting vs. my method explicitly tells it to point to the root partition for Linux Lite.

Because of some customization done to grub files in Linux Lite, ability to boot into LL won't work properly if a different distro's root partition finishes the install.  You'll end up getting the message you got.  If LL's root is the one in charge of booting you won't have any problems.  So easiest fix is to make sure LL is the one in charge of booting.
