Dual boot windows xp + Fedora 5.0 and GRUB missing

Windows + Fedora dual boot
I recently installed a new hard disk aside my existing one. So the new configuration was a 80GB + 40GB. I installed Windows xp on the first hard disk and Fedora Core 5.0 on the second one. And the simple problem that I faced , was that GRUB was simply not coming. The machine would simply boot into windows withou any trace of a boot menu or grub anywhere.
And once again began the hunt for solutions. Asked many Linux experts and all of them asked for the grub.conf.
But I could simply understand that GRUB wasnt installed at all so analyzing the grub.conf was useless. I myself analysed it and found no problems.
Most of the forums suggested to boot using the Fedora DVD and enter the rescue mode and run the grub install command
grub-install /dev/hda
So I booted using the dvd and entered into the rescue mode like this
boot: linux rescue
Then followed a few general localization questions. Then it searched for Linux installations and mounted it to /mnt/sysimage directory. And then requests to type in the command
# chroot /mnt/sysimage
Then I tried running the grub install command
# grub-install /dev/hda
But this did not work and I got the error
/dev/hdb...
