well i installed again Zephyroth 10.5.2 rev 2, because i did miss something yesterday...i didnt choose MBR within DiskUtility when installing Leopard. Today i chose it, i isntalled the MBR Boot Loader , but still my Leopard wont boot.

Can anyone at least give me a hint what to do to boot leopard from hdd? I tried adding it to my Vista Boot loader but actually my hdd is not seen by vista for some strange reason... --- actually it is only seen in Vista`s Disk management, not as a drive (d,e,f etc) in windows explorer , so i cannot choose to boot from it from within the vista boot loader
