Can't Load Ubuntu 10.04 After Installing Fedora

[PDCollins]

I download the latest Fedora live disc to try it out for a little while. I decided to install it to my hard drive to have both Ubuntu and Fedora. I went through the process and had it compress Ubuntu (I guess it moved the files together but I'm new to this so I can't be sure.) Now when I have the startup screen to pick either Fedora or Ubuntu, Fedora works properly but Ubuntu gives me Error 13. It can't find the kernel. I went into the command line and went to where I knew Ubuntu was saved (hd0,0 and Fedora is hd0,2) and ran cat /etc/issue to check that it was there (read somewhere online to do that) and it returned with: Ubuntu 10.04 LTS \n \l

I think all I have to do is edit the pre-boot options or something, as they are way different looking than Fedora's and I think they may just be insufficient. Please help all of my important files are saved on Ubuntu. Thanks.

As a side note, a 59GB File System is mounted in Fedora, and I see that it has all of my Ubuntu files. Is this able to be run still as Ubuntu?

You might have to reinstall Grub 2 using the Ubuntu 10.04 Live CD.

Grub/XP/Vista Bootloader - Ubuntu Forums

You can also google reinstall Grub 2 with Live CD.

Then when you get Ubuntu to boot back up you can sudo update grub in Ubuntu to pick up on Fedora.
