I had windows 7 Pro installed on a Shuttle. When I moved to the NUC I moved it to there and then I upgraded to windows 8 using an upgrade version. Works fine.
Thanks, I will go a similar route. Hopefully I have windows 7 installed correctly on a flash drive and I will try to install that first and then install windows 8.
Hello Spooky Puff 66,
Your last reply is the best way to upgrade the operating system. Please note that there are no hardware limitations to install Windows* 8 in any of the NUC units.
