I have been trying to install a recently nLited copy of Windows XP OEM(or VLK??)with SP3 pre-slipstreamed (...I personally slipstreamed f6 critical MB drivers with nLite as well!!) in Oracle Virtual Box,and keep getting "previous windows os missing...((need previous windows os to continue..??)) to upgrade ((??)) ; i was wondering if there was any workaround for this XP setup "error" (IMO!!) that could be implemented to install this Windows XP edition without being prompted for a "previous up-gradable windows os" in text mode xp setup????
