There is a file named /boot/grub/menu.lst in ubuntu. I have copied the
first entry from there and post that on fedora /boot/grub/grub.cfg
which is as following -

"title Ubuntu 9.04, (kernel 2.6.28-19-generic)
root (hd0,0)
kernel /boot/vmlinuz-2.6.28-19-generic
root=UUID=e9918b34-80aa-4214-bd63-6b46b339005c ro quiet splash
initrd /boot/initrd.img-2.6.28-19-generic
quiet"
I have only replaced " root (hd0, 0)" with the uuid part.
Since then I can usually work in my ubuntu.
Kindly look at the link

and GIVE ME SOME SUGGESTION IF I have committed some error.
