Okay, so I did something stupid. I was trying to clean up my Grub entries, and accidentally removed all of my Linux kernels from Grub (they're still on the hard drive). So now, obviously, Grub doesn't give me any way to boot into Ubuntu; I can boot into Windows just fine, but Ubuntu isn't even listed.

So I just want to run "sudo upgrade-grub" somehow to restore Ubuntu to the list. I can boot from a LiveCD, but once there how do I run that command? (My Ubuntu installation is on sda5, by the way.)

Thanks for all the great help! However, in the end nothing seemed to work, and since I had a separate /home partition, I was able to reinstall Ubuntu without losing any data. I still have to reinstall programs and do some configuring, but everything seems good at this point.
