I have a similar setup, with F7 on sda (1st SCSI hard disk) and Win2K on 
sdb (2nd SCSI hard disk).

The trick is that Windows wants to boot from the 1st hard disk.  The 
solution is to have GRUB tell it that the 2nd HD is the 1st one.   See 
below for a snippet of my config file.

Hope this helps.
