Yeah - It'll be chroot /mnt/sysimage/
you'll need to run grub-install. This will replace the first 512bytes of 
your primary disk with the grub bootloader.

You'll be able to access your windows slice (but I would recommend not 
doing that ;-)) by editing grub to point to it your dos slice. You'll 
need these options - obviously change (hd0,0) to point to your windows 
slice:

 rootnoverify (hd0,0)  
 chainloader +1
