Not able to dual boot after installing RHEL 5.2 over Windows XP

[AchyuthaRao]

Hi,
I have two hard disks: Seagate (SATA) -> 320 GB, on which Windows XP is installed
and the other one, Samsung (IDE) -> 40 GB, on which Linux (RHEL 5.2) is installed.
Plese note that previously I had only the 320 GB hard disk containing WIndows XP and then I added the 40 GB hard disk and went on to install Linux.
But after installing Linux, I am not able to boot WIndows XP at all. While installing Linux, I had never touched the Windows hard disk (am telling this w.r.t the installation options that I got during Linux installation).
Please find below the contents of /boot/grub/grub.conf file. Kindly resolve my problem of dual booting. I even chose the 320 GB hard disk as "first bootable" in BIOS settings -> Boot Order, but even that does not work out.

Does Linux OS boot up fine?

Edit grub.conf file ( title Other ) and set Linux Hard disk as First Boot Device in BIOS.

title Other
rootnoverify (hd1,0)
map (hd0) (hd1)
map (hd1) (hd0)

You can replace title of Windows Code from Other to Windows OS or anything you like.

Dear Sir,
Thanks a lot for your guidance..my system is dual booting properly now...
By the way, the two lines that you have mentioned in the grub.conf code (map) is to map the two hard disks I have to one entity, so that while dual booting, I can do so by considering the existing operating systems in both the disks..is my understanding correct? please correct me if I am wrong..
Thanks once again,
