If you can work on a car you can damn sure work on a computer. Formatting the HD/installing an OS is a piece of cake. I know on macs there is a button you press to boot from cd. I believe you hold down the OPTION key while it's booting. Then just make sure you set your partitions how you want (IE, do you want it split into different parts or not).
