Hi,
 
I'm new to Ubuntu so all of this is new to me.  I installed 13.10 and had a 
GRUB issue with it, so I ran a boot-repair DVD and that solved the GRUB issue 
in 13.10.  After opening my brand new 13.10 OS, it asked if I wanted to upgrade 
to 14.04.  I did and I get the "grub_term_highlight_color not found" error 
every time I boot my computer.
 
Here's my output for debconf-show grub-pc and parted -l:

I tried the steps in #27 (chrooting /tmp/drive and dpkg-reconfigure grub-pc) 
and #130 (chrooting /tmp/mount-point and then did dpkg-reconfigure grub-pc as 
suggested in #27) but neither of them worked.  I chose sda5 as the partition 
for the /tmp/drive and /tmp/mount-point to mount /dev, /proc, and /sys as that 
looked to me to be the drive where Ubuntu is installed.  In the 
dpkg-reconfigure grub-pc application, I (1) left the Linux command line blank, 
(2) left the default "quiet splash" as is in the prompt, and (3) made sda the 
drive for reconfiguration. 
 
I'm at a loss what to do.  I'd like to have the option to dual boot to either 
Ubuntu or windows but I can't do that as long as GRUB is broken.  Do I need to 
delete and re-install GRUB 2.02 or do I have to downgrade GRUB 2.02 to 2.0 or 
what?
 
P.S. When you mount something in the terminal, does it really mount it even 
though the terminal just displays another prompt and makes no indication that 
anything was mounted?  If it's supposed to say something, then maybe I mounted 
the files wrong.
