Hello, Im really a novice when it comes to Macs. My buddy recently sold me a Macbook Pro, but he told me I needed to replace the hard drive. So, I purchased a SSD and installed it. This is where I get stuck. Purchased Snow Leopard install disk, but I first must format the SSD and I'm unsure of how to do that. Right now, when the Macbook is turned on, all i get is the flashing file with the question mark. No chime. No anything. If someone can guide me through formatting the SSD and installing the OS, I would be very grateful. Thanks in advance for your help.
