Installed Linux....Unable to access Windows partition

[imhotepmp]

My setup is the following:
Drive1(primary,master),partition1 Win2k
Drive1,partition2 Win2k program files and other files

Drive2(primary, slave)-RH 7.3 (/boot,/,/home partitions)

During the RH installation I chose GRUB as the boot manager. After finishing the install, GRUB window pops up, but there is no choice for me to boot up windows. The only choice listed is the RH installation. My question is, without reinstalling how do I get access to my WIn2k installation, I tried modifying the /boot/grub/menu.lst by adding:

title NTroot
(hd0, 0)
makeactive
chainloader +1

i got this from my Mandrake installation on my laptop. Here is the full file:
menu.lst:

# grub.conf generated by anaconda
#
# Note that you do not have to rerun grub after making changes to this file
# NOTICE: You have a /boot partition. This means that
# all kernel and initrd paths are relative to /boot/, eg.
# root (hd1,0)
# kernel /vmlinuz-version ro root=/dev/hdb3
# initrd /initrd-version.img
#boot=/dev/hda
default=0
timeout=10
splashimage=(hd1,0)/grub/splash.xpm.gz
title Red Hat Linux (2.4.18-3)
root (hd1,0)
kernel /vmlinuz-2.4.18-3 ro root=/dev/hdb3
initrd /initrd-2.4.18-3.img
title NT
root(hd0, 0)
makeactive
chainloader +1

after modifying, the NT option shows, however it wont boot up and just gives a command not found error. Any ideas how I can modify it to boot up? Am i even modifying the right file?

thanks
