I have an iBook, and because that is intel I had to use parallells to install windows, but as someone else said, parallels will let you install any OS. So far as I know, if your mac is compatible with boot-camp, that will too. It all depends on the specs of your MAC. Google it- I did. My PPC G3 was unsuitable for any of this, the iBook needed paralllels.
Linux is not the problem at all- wrong question. Don't take my word for it about the specs, this is off the top of my head. But <b>the right question would have been 'which method can i use on my macbook?'.</b>
I agree there is no point in having linux- PC friends are always on at me about this, and fail to understand when i say 'don't b silly, this runs on unix anyway'. However, i guess you must have some special need....?
If not, don't bother.
