    It looks like GRUB is still confused about disks and partitions.
    Could you boot with the rescue CD (or CD1 with "linux rescue") and get
    us the output of "fdisk -l" (the full output, please). The first
    error, the unknown partition type means that it is either trying to
    access you Windows disk, or the partition has the wrong type number.
    Also, what does your /boot/grub/device.map contain now? If /dev/sda
    is mapped to (hd0) and it contains your Windows install (I believe
    that is right), then the numbers in your grub.conf need to be switched
    around.
    So your Windows section would be:
    title Windows
    rootnoverify (hd0,0)
    chainloader +1

    Linux would be (smp is going to be similar):
    title Linux-up (2.6.9-1.667)
    root (hd1,0)
    kernel /vmlinuz-2.6.9-1.667 ro root=LABEL=/ rhgb quiet
    initrd /initrd-2.6.9-1.667.img

    And you should also change the "splashimage" line to point to (hd1,0).
     To see if this will work, you can try booting Windows manually. When
    you have the GRUB boot prompt hit Esc (escape key) and press 'c' to
    bring up a command line. Then type this:
    rootnoverify (hd0,0)
    chainloader +1
    boot

    If Windows then boots, you should make the changes I suggest to you
    grub.conf, and things should work. By the way, I assume you SMP entry
    is not how you show it (you are missing the "root" line and part of
    the "kernel" line is up with the title).
