hdd wont show in installer

[ShadowLegion88]

I'm trying to dual boot vista and mac using iATKOS 5i and the installer won't show my drives and is starting piss me off. I activated the mac drive a made in vista so now I can get back into vista cuz the drive that's active doesn't have a OS. I can't tell you all my specs cuz i'm on my iPod typing this but I can tell you it's a computer that I built.

Intel Pentium Dual-Core Processor
Foxconn Motherboard
ATI Sapphire HD 3850
2GB Ram
