I have 2x Acer Aspire One and 1x Lenovo S10-2 netbooks. They all have hidden partitions from which they execute windows installation when its triggered by special button or key combination during boot process. Is it possible to edit these installations in way nLite is doing so with CD installations and upgrade / configure / add addons, drivers etc.? I also thought that it would be very nice to replicate this netbook feature to desktops - only triggering could be established by specially made USB boot key with special boot loader settings [grub for instance]. Could this be done or does this feature already exists?
