Ubuntu :: Crashed After Update - Error "You Need To Load Kernel First"

I am having a Ubuntu nightmare. I am relatively new to the whole Linux thing. I just updated my Ubuntu from the update manager today and after I restarted I keep getting the following error: Error: You need to load kernel first.

My boot menu shows the following:
GNU Grub version: 1.97~Beta4
Ubuntu, Linux 2.6.31-21-generic
Ubuntu, Linux 2.6.31-21-generic (recovery mode)
Ubuntu, Linux 2.6.31-20-generic
Ubuntu, Linux 2.6.31-20-generic (recovery mode)
Ubuntu, Linux 2.6.31-14-generic
Ubuntu, Linux 2.6.31-14-generic (recovery mode)
Windows 7 (loader) (on dev/sda1)

The only two that work are the last two. So I chose Ubuntu, Linux 2.6.31-14-generic and booted normally. From there I typed actionparsnip's suggested solution (which worked for other people on other versions): sudo apt-get clean; sudo apt-get --reinstall install linux-image-2.6.31-21-generic As you see I suited actionparsnip's solution to my version. The command downloaded something and made some fixes/updates and everything and seemed to have worked fine.

The system asked me to reboot, and here I am stuck: Now the boot menue shows the grup prompt which seems like: Minimal BASH-like line editing supported... sh:grub> NOTES: I originally installed Ubuntu alongside Windows 7 using Wubi. I can paste the contents "wubildr.cfg" if this helps. I had to go back to my Windows 7 to post this.
