Myles999, I am sorry to hear you are having problems with your new NUC, but I will be more than happy to assist you on this issue.
I was reading your comment and it looks like you already performed all the recommended troubleshooting on this type of product. However I will like to know which BIOS version you are trying to install through a BIOS recovery?
The latest BIOS I could find was FY0025.bio. I downloaded it a couple of
times onto different USB sticks after the initial failure, just in case there
was a problem with the download or with one of the sticks. No success. After repeating the
recovery procedure a number of times on different display/cable combinations, I
even tried recovering the previous version (0021) just in case that might at
least display something and let me into the BIOS. No luck on anything.
I have now contacted Intel support center and have supplied some more info to them that they asked for. All I can hope for now is that Intel will indicate that the unit appears to be faulty so that the retailer will agree to issue an RMA.
