Hey! After two days of apathy this thread is getting busy! First thanks to all who took an interest in my little problem. Second, I think a number of points need some clarification to avoid further congestion of the thread and wasting the precious time and goodwill of all involved in the matter. I’m the proud owner of two OEM copies of Windows XP. The first one was originally purchased alongside some other hardware when I built one of my systems. It comes in a shiny, beautiful CD all covered in anti-piracy holograms (people using pirated copies of Windows don’t know really what they are missing. The second copy of XP came with my ThinkPad notebook. It is typical OEM pre-installation affair. So no activation is required but no CD is provided neither, only the annoying service partition. In other words an ideal candidate for that lovely nLite to work its magic on. So I tried … and failed miserably when, during the GUI part of setup, I was asked to introduce the keys for the product, as I described in my first email. Strange fate indeed as the copy is 100% genuine. The instructions on the nLite website are clear enough, and really there are little options for an end-user to cock things up. But because I was using not an original OEM installation of XP but one that IBM has already being tinkering with (and these guys know a thing or two about how to tinker a PC since they invented it!) I thought that nLite had failed to do their job properly and corrupted some file or maybe IBM’s evil corporate mind had deliberately wanted to frustrate any attempt by their end-user to create a working CD based on the original I386 folder. But please prospective helpers, understand that my main motivation for starting this thread is theoretical rather than practical. I want to know what went wrong and why and not so much how to get through this problem by using other copies or versions of XP –although of course any suggestion in this area is very welcomed and appreciated. Since most ordinary computer users are using precisely this pre-activated versions of XP and rarely have access to an OEM or retail CD version, I thought the subject was indeed relevant not just for me but for that multitude of CD-deprived souls. I know there is no problem in building a CD based on an original I386 folder but what I would like to know is if royalty OEMs (IBM, HP, Dell) and in particular IBM allow this to be the case in the copies of windows they distributed with the equipments they sell. Believe or not it is extraordinarily difficult to come by with a definite answer (at least in the case of IBM) searching the web, hence coming to the forums which is always my last resource. I would like also to establish if the failure in completing the procedure is due to OEM’s antics or caused by nLite’s unawareness of the fact that is dealing with a “dirty” copy of XP. Being such a common scenario I really thought that some people would already know. I’m so intrigued by all this that I’m going to carry on some research to find out who really is the bad guy in this story. Shortly I will try and build the CD without using nLite and I will report back to the forum members with my results. This time I’m not going to point the finger to anyone. To put an end to this overlong posting, just another piece to add to the jigsaw. I booted the other day into my thinkpad using a Bart CD and ran winnt32 (the version of setup that runs under windows not the one who starts from the CD). When prompted to provide the product key I did so. And guess what? This time round the generic key and the key on the sticker worked beautifully. Whoever understand all this and is willing to share its wisdom can get a beer on me… Thanks for listening keep posting.
