Trouble updating grub? Error: the symbol 'grub_getcharwidth' not found.


Hello,

I just installed Ubuntu 10.04 and everything was working fine. I also have Win XP installed and Ubuntu 9.10. I was able to boot any of these OS's with no problem.
Without understanding the ramifications of my actions, I enlarged the Windows partition to incorporate the unallocated space at the beginning of my disk using Easeus Partition Master from within my Windows OS. Apparently, I wiped out my grub!
I have been able to boot to my 2.6.31-14 kernel (Ubuntu 10.04) using commands from the grub rescue prompt.
Upon successful boot into the system, I initiated the command: sudo update-grub and my system still reports Error: the symbol 'grub getcharwidth' not found.

Here is my grub.cfg:

Thank you very much for your help. I am a noob trying my best to learn. I have already researched this problem for a couple hours. I know I must be close to resolution, but I can't seem to fix it on my own. ;-)

Regards,

Ed
