Firstly forgive me if this has been covered before;
We have several Nucs running fine with the exception of two D54250WYK kits we are evaluating.
One with RedHat 7 Desktop and the other with Windows 7pro
All worked well for the first week or so, but on re-booting either system an error message pops up
Image autherization fail
System cannot boot to this device due to a security violation
Press enter to continue
Any thoughts or ideas would be much appreciated
Many thanks
