The mapping of HDs is for GRUB is different than on Linux. If your 
Windoz partition is the first partition on the first IDE HD it is 
/dev/hda1 in Linux and hd(0,0) in GRUB.

You could build a Windoz boot floppy http://www.nu2.nu/bootdisk/ntboot/ 
and boot with this. If the floppy is booting your Windoz, the Windoz 
installation is fine. That means it is just a matter of configure GRUB 
correctly.

If you boot and see the GRUB boot prompt, you can hit the c key to get 
in console mode. Write help and hit enter. Now, you see all commands 
from GRUB. There should be one which shows you the partitions GRUB sees. 
Find out which partition refers to your windows partition and enter 
following commands:

root (hd0,0) <- this has to be your Windoz partition
chainloader +1
boot

Hope this helps.
