    Are you able to boot to linux? Or you are not able to boot to any of the
    OSes?

    I am not sure if this will help or not but I experienced that the SATA
    driver messes up the disk notation. I remember I had to name them as
    (E)IDE drives (i.e., /dev/hdaX, etc) in grub.conf but name it as SCSI
    disks (i.e., /dev/sdaX) in /etc/fstab. In my case, I didn't have windoze
      though. I guess that the SATA drive is recognised as an IDE device by
    BIOS and its actual driver is an SCSI one (after initrd is loaded?). By
    all means it helps using disk labels. Just that map, root and
    rootnoverify commands don't support disk labels.

    I also remembering that you may have to modify the file device.map
    (change IDE-stype naming to SCSI-stype). For example, change "(hd1)
    /dev/hda" to "(hd1) /dev/sda". Not sure if this is relevant since I
    don't know if you are able to boot to linux.

    Good luck,
