Mine shows the following and it works (for Windows):

rootnoverify (hd0,0)
chainloader +1

You showed rootnoverify (hd1,0) - it should work (unless the system doesn't 'see' the disk which seems to be the error you have).

the windows disk should be jumpered as slave to the linux one, this will cause errors.

a lot of people will tell you to mount it in linux, but that's irrelevant since it's not linux doing things with the second drive, it's grub.

was windows isntalled on that HD when it was the only or master drive? if that's the case, then it's going to affect where windows sees tiself as installed at.
