I downloaded the image file but I don't know how to install it. I have a second harddrive on my computer that I would like to install it on, its about 9GB. I want to be able to do a dual boot. can someone help me do this? I just want to install it so I can try out the OS and decide if I want to buy a Mac, so don't tell me to go buy one. Once I install it and I like it, I'll buy a mac.
