Trouble installing 64-bit vista on my Mac Pro

[Jmac10]

Hi, i have been using my new mac pro for just over a month now with snow leopard and 32-bit vista installed successfully. I have decided i would be stupid not to take advantage of my computers hardware and get the 64-bit edition of Vista, especially because of the rendering and 3D software i use. My hard drive has already been partitioned using bootcamp so i could install the 32-bit version of vista, but when i try to use the same method again for the 64-bit edition it tells me i cant for this reason. I would like to have Snow leopard, 32-bit Vista and 64-bit Vista installed on the same hard drive at once for various reasons.

I am aware that disk utility can do the same thing manually but i do not want to use the 'trial and error' method i usually use because of the work on my hard drive

Could some one please explain how i can achieve this???

Triple booting your Mac on one HDD is not an install that there is a nice installer to hold your hand through the process. You will either have to get your hands dirty or try another approach.

You have a Mac Pro. You are not bound to a single internal drive. The easiest way is to add a HDD for each OS, or at least for the third one.

Yeah i was kinda expecting that...

Ive already had a look at some new hard drives and western digital looks good.

This is the link to the WD Caviar Black 1TB SATA Drive...Tell me what u think...
