Hi, I'm a newbie home Linux user. So don't think I know what I'm writing
about ;) but according to the docs on my system I see 2 possible problems.

1) You could be missing the Grub <makeactive> command according to the
docs files on my computer:

From my Fedora Core 2's /usr/share/doc/grub-0.94/menu.lst
                                                                                                                                                            
# For booting Windows NT or Windows95
title Windows NT / Windows 95 boot menu
rootnoverify (hd0,0)
makeactive
chainloader  +1
# For loading DOS if Windows NT is installed
# chainload /bootsect.dos

From my Fedora Core 2's <info grub> terminal command

     # For booting Windows NT or Windows95
     title Windows NT / Windows 95 boot menu
     root        (hd0,0)
     makeactive
     chainloader +1
     # For loading DOS if Windows NT is installed
     # chainload /bootsect.dos

2) <info grub> also shows special commands when booting Windows from a
second hard drive:

"   If you have installed DOS (or Windows) on a non-first hard disk, you
have to use the disk swapping technique, because that OS cannot boot
from any disks but the first one. The workaround used in GRUB is the
command `map' (*note map::), like this:
                                                                                                                                                             
     grub> map (hd0) (hd1)
     grub> map (hd1) (hd0)
                                                                                                                                                             
   This performs a "virtual" swap between your first and second hard
drive.
                                                                                                                                                             
   *Caution:* This is effective only if DOS (or Windows) uses BIOS to
access the swapped disks. If that OS uses a special driver for the
disks, this probably won't work."
                                                                                                                                                             
 
Hope that's more help than hindrance.

Doug
