grub problembetween redhat and fedora


Hi!
Friends,I have installed win xp and win 7 on my laptop.I installed redhat 5.2.Everything was ok uptill now.Problem took palce when i installed fedora 11 after redhat.After the complete installation i was unable to boot into redhat.I read about this problem on internet,they say its a GRUB problem,that it,gets overwritten during installation,that is ,fedora overwrites redhat's GRUB.I tried to install redhat's grub to it's root and added redhat to fedora's booting list during fedora's installation,but system could not boot in redhat.Can anybody tell how to install redhat and fedora over the same system?Any help would be appriciated.
THANKS.

First you have to install Redhat's grub to Redhat's root partition and then you can chainlod to it using fedora's grub.

Grub natively boot any of the linux distributions, so no one needs this chainloader tricks. Just open menu.lst of redhat, and copy entries for booting up redhat in fedora menu.lst
menu.lst should be placed in /boot/grub/menu.lst

Can you open a terminal and log in as root in Fedora. Do that and then enter 'su' or 'su -' (without quotes). Then type from the root prompt:

vi /boot/grub/menu.lst

It's pretty hard to advise you without knowing your partition information and what is where. As root in terminal, run the command: fdisk -l and post that information here.

On RH style systems, the real file is /boot/grub/grub.conf. 'menu.lst' is just a symlink.
