There is no other way to hack your bios or windows other than to use a loader. However, under Microsoft Windows 7, there is a new technology that is called W.A.T. (Windows Advantage Technology) which, as far as we know now, is able to detect loaders, patches, cracks and bios emulators and will render your windows into limited mode and won't let you use the internet or many other features until you make Windows 7 to be authentic. So, hopefully you will be one of the few who can fool windows 7 that your copy is genuine.
