i want to select the mac os install partition

I'm back from the month long hiatus, here is what i have right now:
a windows XP partition
a windows 7 partition
a windows vista partition
a windows 8 partition
i'm willing to sacrifice the vista partition for the mac OS partition but i don't know how to use clover so i guess i'll look into it now
(i may also have to completely redo the bootloader because windows will think vista still exists)
it also looks like the clover guide requires a mac or a linux computer, neither of which i have
