Hey there, I'm currently running Windows 7 and I'm trying to partition my hard drive so I can dual boot Mac os x Leopard. I have 133 GB free on my 230 GB internal hard drive, but when I partition the drive the computer will only let me open about 5 GB of space. I have defragged the drive and nothing changed. I am new to dual booting and I am really only doing this as an experiment. If anyone can give me any advice as to how I can partition more space or how much is needed I would be very grateful. Thanks.
