How to edit the Boot file
 

Hi everyone I installed 3 OS in my computer, first Windows xp, second Ubuntu 10.10 up to here I could go in to each one of them, but I installed Fedora 14 x64 after Ubuntu. Now I can only go to Fedora and XP, but I am not able to even see Ubuntu only in the shell, it is not in my boot options.

You don't need to touch any boot file, you need to re-load Grub2 from the live Ubuntu CD. When you installed Fedora, it installed its own version, I'm not sure if it uses Grub or Grub2 but it looks like it doesn't understand Ubuntu.
I found this when googling "Installing Grub2 from Ubuntu Live CD"

Thank you for your response I'll try to fix it with the Ubuntu cd.
