A friend of mine got this laptop: VGN-FZ140E which is Intel Core2 duo 1.8 Ram 2g HDD 200g and is unable to install Xp on it. it came with Vista pre-installed on it and he says that he cannot install xp on it! he's no noob or what, so i know its somewhat tricky. is there any special trick to install windows xp on these machines which came with Vista pre installed? TIA.
