However, now when grub loads the message I see is "Grub loading Stage1.5". I do not see *any* further output. I'm guessing that this means that grub failed to load stage 1.5. Since stage 1.5 is supposed to be right after the MBR, I'm thinking that perhaps something in Windows is not playing nicely and is overwriting it stage 1.5 ?

If I boot from a CD and run `grub-install /dev/hda`, all is well.

I suppose that when you run this command grub embeds stage1_5 in
whatever place it embeds it.

The quick trick for avoiding this is forcing that stage1 loads stage2
directly instead of stage1 loading stage1_5, and then stage1_5 loading

How do we do it? We only have to "remove" the stage1_5 files.

Once you've made that you've got to re-run the
# grub-install /dev/hda
command (it will complain: I cannot find stage1_5 but this is not fatal)
and of course, to tell us if everything goes fine without you having
problems once you reboot into windows 3 or 4 times.

Thanks for the advice. Forcing stage1 to load stage2 directly does indeed seem to have worked. However, in order to do that, I had to modify grub-install. By default, grub-install would copy the stage1_5 files into by boot directory. After a couple quick edits to create a modified grub-install, I was able to get stage1 loading stage2. I haven't had any problems since.

This is why I always use the root and setup commands manually. :)
