After reading many a post I have not yet found this particular problem with installing Windows on my Intel MacMini. After partitioning the HD through Bootcamp running through recently installed Leopard I insert my copy of XP Pro SP2 and the MacMini restarts. On restart the DD whirs into action but as it begins reading the disk the screen 'cuts out' and the computer stalls only to come back to life once I power off and restart holding down 'Alt' and selecting Macintosh HD. It recognises the Windows disk at the restart menu and also the copy of Windows works through a Parallels installation. I mentioned the problem to my local Apple reseller and he informed me (perhaps unsurprisingly) that it was down to the fact that I have an OEM (cheap) version and not the retail (expensive) version. Is this true or mere sales patter? Any help would be greatly appreciated.
