You have to some work but trivial dont worry

First of all ubuntu karmic have new grub loader 1.97beta6..., so there is
menu.lst in /boot/grub instead /boot/grub/grub.cfg is the file
and config files are available in /etc/grub.d folder

Recovery should be like this
  Boot into live CD
  open Terminal
  type in commands as follows
*      sudo /dev/sdax /mnt*  (sdax is the ubuntu karmic partition, if you
dont know go to system --> administrative-->disk utility and find out)
*      sudo grub-install --root-directory=/mnt /dev/sda* (drive name)

This should give you grub menu at start

if you want to add any entries append your grub entries like below
  menuentry "Windows XP" {
            set root=(hd0,1)
            chainloader +1

and then type in command
*  sudo update-grub*

Hope this helps, please find yourself more information from grub2 ubuntu
