I realise that this topic has come up before, but seeing as I'm probably less experienced than other forum members in using the Acer Aprire One, I thought I'd post this anyway. Having said that, let me add that I [u]AM [/u]a reasonably proficient computer user when it comes to my own laptop (Acer Aspire 5105WLMi), with Vista Home Premium as the OS. Eighteen months ago I had to buy an Acer Aspire One for my six-year-old son for school, with Linux already pre-installed; he merely learned the rudiments of opening programs, sending an e-mail, playing games and opening internet etc.. This year, however, he's changing schools and at the new school will be using the computer lab, where the computers are all fitted with Microsoft Windows (probably XP). Rather than have his Aspire One sitting in the wardrobe gathering dust, I thought I would remove Linux and install Windows XP and a decent antivirus program. But I don't really know how to go about this. I have an XP professional CD lying around here somwhere. Should I save it onto my own PC and then transfer it to a pen drive so as to be able to install it on the Aspire One? How do I remove Linux and everything on the Aspire One? Once that's done, will the netbook automatically extract XP from my pen drive and install it? The procedure is probably very simple, but I don't want to make any irreversible mistakes and so would appreciate some simple, step-by-step instructions if someone can be bothered helping me out. Thanks a lot, Florio
