Not being a techie I have decided to have a go at using boot camp to install Windows XP. I have watched several videos on youtube and printed out the guide as suggested by Mac. To cut to the chase, why is a USB keyboard and Mouse required for the installation and at what stage do I have to use them? I have only just purchased Logitech S530Mac keyboard and mouse bundle, so am I not able to use these. I have the latest Mac Mini.
