Installing boot for a computer having Win + Linux after installing Windows

STEPs:

1. Put the CDs of the RedHat Linux installation
2. Reboot your PC
3. You should now see the boot screen from the CD
4. Type: linux rescue <ENTER>
5. Follow the instructions until you get a screen asking you whether to continue with mounting an existing RedHat Linux partition or not, select continue. This will mount the found portion on '/mnt/sysimage', in the command prompt, type : chroot /mnt/sysimage
6. To install the boot type: /sbin/grub-install /dev/hda
7. Reboot your system, and I wish that you will get the expected RedHat boot screen to chose the operating system you want to start.
