DO NOT PUT LINUX ON NTFS.
BAD!!!!!!
SUSE likes Reiser FS and I say give it to it (or ext2 or 3 .. whatever).
Disks are divided into partitions so that multiple OSs can be put on (in fact it is there to keep some data seprate from others, but I digress)
The first thing we need to do is get you into some environment to actually modify things.
This is where the SUSE disk comes in, there is a rescue mode you can get into:

I am pretty sure the default for SUSE is to have just one partition (swap aside), but either way once you have mounted your hardrive open up your fstab in some text editor
or
or
This will tell your partitioning scheme
I need to know what device /dev/something is your windows partition and which is your linux boot partition (or just your linux partition, if don't have a seperate boot)
The goal is to have grub boot off of your suse partition
The next thing I need you to do is to make sure that there exists a file in /mnt/boot called menu.lst or grub.conf ... note this night be in a grub subdirectory. Don't worry about the syntax yet, if that isn't right, we'll see the screen and not get into linux, but the windows line should be very standard
title=Windows Whatever
root {location of windows partition, see below for naming}

chainloader +1
The final thing we are going make sure grub looks to the right drive for the conf file, all drives are index by two numbers the first is which drive and the second is which partition on the drive.
You said you have you partitions so in fstab you will see drives like /dev/hda1 or /dev/sdc2
The first two letters will be hd if IDE or sd if SCSI
The third letter indicates the drive's relative position - all I want to know is which one comes first
The third is the partition number
Grub starts counting at zero so for example if you had two drives hda and hdd, hda would be drive 0 (the first one) and hdd would be hd1 (the second)
if you linux partition is is /dev/hda3 (which I imagine it is)
grub sees that as (hd0,2)
so now we type grub and get into it's little command prompt
now type
root {where ever your linux partition is} ---- example : root (hd0,2)
press enter and now
setup {which ever drive you boot off of} ------------ example (hd0) This installs grub into the Master boot record
then quit
now restart, hopefully you will see a GRUB screen and have a couple of nice options
[edit] this isn't an exact algorithm to run, it is a guideline, if you need help, post and I'll help. [/edit]
