I have solved the problem other way -
1. Booted the system with Live CD
2. Manulay search all the drive to find the folder "boot/grub/menu.lst"
3. Right click on menu.lst> click copy
4. open Terminal> click paste (here pasted /media/disk-?/boot/grub/menu.lst
5. preceded the pasted command with "gksu gedit"
6. final command
Code:
gksu gedit /media/disk-?/boot/grub/menu.lst
7. menu.lst files open and change the value of {hd0,?} to (hd1,?} for all the ubuntu boot sequence except the Windows OS, rebooted the system and the problem solved for grub loader.
UTMOST CARE should be taken to modify Menu.lst file else it may not be start Win OS also. Always keep bakup of menu.lst file before doing any alteration.
