How about adding an entry in grub.conf that is similar
to how we boot windows from grub:

title Ubuntu-9.04
        rootnoverify (hd0,0)
        chainloader +1

I do not know which disk/partition your ubuntu is on,
so you have to adjust (hd0,0) accordingly.

This will work, if you installed ubuntu's bootloader on it's partition.

Thank you JD for you suggestion. I have taken the following steps-
 

Step1:
I add
[QUOTE]title Ubuntu 9.04 kernel 2.6.28-19-generic
root (hd0,0)  
kernel /vmlinuz-2.6.28-19-generic root=/dev/sda1
initrd /initrd.img-2.6.28-19-generic
---------[/QUOTE]
Step2:
[QUOTE]title        Ubuntu 9.04, kernel 2.6.28-19-generic
uuid        e9918b34-80aa-4214-bd63-6b46b339005c
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[/QUOTE]
Both time after restarting the computer and selecting ubuntu in GRUB list gives me this error message
" Error 15: File not found
Press any key to continue..."
Step3:
Then I edited the grub.conf file again and add
[QUOTE]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[/QUOTE]
And then there is no problem in logging into my ubuntu system.
