Use Super Grub disk. It can make any partition you want (Red Hat in your case) bootable.

hello but i heard that ther are some commands ..by which we can retrive linux back..

Boot up in Rescue (Recovery) mode using RedHat Installation CD/DVD. Execute this at shell prompt :

chroot /mnt/sysimage
grub-install /dev/sda
exit
exit

Machine will reboot and GRUB menu will appear at startup.

There are two methods to re install grub...

1st method...
Boot up in Rescue (Recovery) mode using RedHat Installation CD/DVD. Execute this at shell prompt :

chroot /mnt/sysimage
grub-install /dev/sda (for SCSI HDD) or /dev/hda
exit
exit

if 1st method does'nt works u can try the below method..
# grub (jus hit enter)
grub>root (hd0,0)
grub>setup (hd0)
grub>quit
