win 7 leopard and snow leopard are all on the same drive but in different partitions
the problem with gparted is that after using it on osx (leopard) chameleon recognizes that os (leopard) as a linux one and doesnt allow me to boot it
my leopard has stopped working due to this and i dont want it to happen to snow leopard too
but the solution u have suggested could u please elaborate
thanks
