Thank you for joining this Intel Community.
I understand that you would like to get more information about the difference between 16.04 LTS for Intel® NUC and Ubuntu 16.04 LTS for other systems. I would like to provide more information about it.
Standard images of Ubuntu may not work at all on Intel® NUC or may not work well. Ubuntu 16.04 LTS has been certified to allow users to make the most out of this operating system on our Intel® NUC. Keep in mind that Intel hasn't validated these operating systems. If you need assistance with Linux* on Intel NUC, check your distributor's website and forums for peer assistance.
Please find below driver resources for troubleshooting purposes, too.
