Sotirios Papakonstantinou Posted May 18, 2008 Share Posted May 18, 2008 I'm afraid that you cannot install Vista on the same hard disk. Even if you reduce the MAC partition and install Vista on the unallocated space, it will probably modify the disk so it boots only in Vista. So after that you should find a way to include MAC OS X as a dual boot option in Vista's boot loader. I saw a guide for dual boot Vista and MAC but it said we should install Vista first and then MAC OS X. I don't know if you can do it the other way round...
