Could be wrong but I thought the operating system was something you can't change. The computer will be built for that operating system. Like I can't run Windows on my Mac (for me, thankfully!). You can get PC emulators, so I actually can run Windows on my Mac, but only cos it fools Windows it is a PC. Maybe you can get the same of Linux? I've found that it makes it run very slow though (I only use it when I need to use MS Access) so I don't think it is the best solution. Could be wrong though, maybe you can get Windows for Linux, but I thought they were both operating systems, so you can't have two.
