I would like to install windows 7 on my macbook air but have a few questions. I am new to mac so I really have no idea how to do this or what many of the terms mean that are used freely in this forum. Your simplest responses will be appreciated. The install: I can get a copy from my university and but it requires burning it to a dvd. Can I install the dvd using remote disk with my wife's macbook pro? If not what else can I do to get this installed? Use: I have a copy of parallels, but plan to install win 7 using bootcamp and then installing parallels so that I can boot into windows 7 or use it side by side in lion. Will I need to be running an antivirus program even when I am not using windows or running any windows programs using parallels. In other words will my computer be slower when not running any windows programs? I only plan to use windows when I have to so I don't won't to have an antivirus running all the time. Thanks in advance for the help.
