Converting to dual boot after linux installation 1

[PoornimaShashidhar]

I had a system which had Windows NT and OS/2 installed on it. Recently, I installed Redhat Linux 7.2 on the partition that had OS/2 on it, while the Windows partition was untouched. Now I'm unable to boot to my Windows partition. I'm not very sure if I have installed the Linux loader on the MBR or elsewhere. How to identify this?
The contents of my /etc/lilo.conf are as follows:
*******************************************************************************************

 boot=/dev/hda
 map=/boot/map
install=/boot/boot.b
prompt
timeout=50
message=/boot/message
linear
default=linux

 image=/boot/vmlinuz-2.4 2-2
               label=linux
               read=only
               root=/dev/hda

***********************************************************************************************

What are the steps that I need to take in order to enable dual boot?

Thanks in anticipation..

ok in a shell type "cat /proc/partitions" and make an guess at which partition is the one with windoze on it. the big number you'll see next to each partition is it's size.

then edit your /etc/lilo.conf and add

other = /dev/hda3
label = windoze

(this is if you think windoze is on hda3)
