Windows 7 or 8 is possible, Linux and even Android is possible! Windows 10 might be possible with advanced skills, but not for us mere mortals, without lots and lots of time. I already answered this question almost a year and a half ago, and what I said then is still the case. (the possibilities for Android is sorta new) The hard drive on almost all Chromebooks is too small. This is likely on purpose because Google doesn’t want people to put Windows 10 on Chromebooks! If you ARE NOT prepared to learn firmware, a little about hardware and even programming (scripting) it’s not going to work for you.
