You have changed the partitioning since you first installed openSUSE. Originally, the openSUSE root was sda9, or in grub numbering (which starts with 0) that is (hd0,8). Grub was installed to the MBR (hd0), pointing to sda9 (see the /etc/grub.conf file).

To reinstall grub as it was originally, boot from the LiveCD, get into the terminal, switch to root, and do:

root (hd0,4)
setup (hd0) (hd0,4)
After the root command grub should return a message indicating it found the partition and that it is formatted ext2/3. The setup command should return ~7 lines; those lines should indicate that grub stage1 was found, that grub stage2 was found, and that grub was installed successfully. If so, reboot and you should be back to where you were before reinstalling Windows.
