Cannot Chain Load Grub From Windows Boot Loader

[Paul Galbraith]

I installed grub to the boot sector of my linux root partition, and then 
I saved a copy of the boot sector to a file on my Windows boot 
partition, like this:

   dd if=/dev/hda2 of=/win/c/bootsect.deb bs=512 count=1

I then added this line to the boot.ini file in my windows boot partition:

   C:\bootsect.deb="Debian"

This method worked for me with Lilo, but does not work with grub.  When 
I select "Debian" from the windows boot loader menu, I get a "GRUB " 
message at the top of my screen and then the system is hung there doing 
nothing.

Interesting, if I boot from a grub boot floppy, I can chain-load grub 
from my linux root partition, like this:

   root=(hd2,1)                   ;  [(hd2) === /dev/hda]
   chainloader +1
   boot

This loads grub from the linux partition and I can continue to boot 
debian without any problems.  Grub only stalls when chainloaded from the 
windows boot loader.  Has anyone else encountered this problem, or offer 
any insight?  Cheers,

Paul
