I hav two 40 GB hard disks.RHEL5 is installed on 1st and Windows on 2nd.
In order to use each OS I manually hav to go and change the "first boot device" option in BIOS setting and boot into required OS.
GRUB doesn't show Windows in its boot menu.How can I make GRUB recognize Windows and boot into both OS using GRUB boot menu?

Set RHEL as the boot device, and add the following to /boot/grub/menu.lst (or grub.conf if RH still do that)

Code:

title Windows
rootnoverify (hd1,0)
map (hd0) (hd1)
map (hd1) (hd0)
chainloader +1

If that doesn't work, post the output from

Code:

/sbin/fdisk -l

(that's a lower case ell, not the digit one).
