Windows on one hard disk, Fedora core on the other and GRUB nowhere

It was when I installed a new hard disk keeping along the existing one. So the new configuration was a 80GB + 40GB. I installed Windows 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. 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 try 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

# grub-install /dev/hda

But this did not work and I got the error

/dev/hdb does not have any corresponding BIOS drive
Linux was on hdb

After again I searched several forums and somewhere found a modified version for the command

# grub-install –recheck /dev/hda

The I rebooted to discover perfect enlightenment and a cool blue GRUB.

The grub-install –recheck command rewrites the /boot/grub/device.map file
with mappings like

(fd0) /dev/fd0
(hd0) /dev/hda
(hd1) /dev/hdb

So GRUB could install properly.
