if grub is installed in the MBR of the first disk, try:
in your /boot/grub/menu.lst
To mount it you can either manually use the mount command
mount -t ntfs /dev/hda1 /some/mountpoint
or put it in /etc/fstab to mount it automatically on boot/mount by only specifying the device or mount point, eg.
/dev/hda1 /some/mountpoint ntfs auto,umask=222 0 0
windows partition on the second drive is probably /dev/hdb1, check the output of fdisk -l.
