Something is a bit strange here.  Can't have but one (hd0).  Should
presumably be:
   (hd1) /dev/sda

I've run into trouble in the past if grub's device.map differed from the
BIOS boot order on IDE/SCSI machines.

That approach works for me also. [Although I still consider using dual-
boot with Windoze to be evil. :-) VMware is a mitigation. ]
