I am sorry for your issue.
It may also help to post your question in the Linux* Communities since the supported operating systems are Windows* 7, 8, and 8.1.
Thank you for the answer yes you are right there is now Windows installed and Linux is not supported.
In the meantime I did try whit several versions and different Linux'es distributors, but there is always the same issue.
In the BIOS settings there are the following Problems
- No Wake Up on LAN.
- Headless Configuration problems.
- s4/s5 Deep sleep problem.
This issues make the Box hard to use as an PVR Media Server, the NUC concept is great good CPU,Memory and SSD configurable low power consumption great stuff, but as soon as you are reaching the BIOS settings then you get lost.
