Hello Risaacma, I would like to inform you that based on the fact that Linux* is not a supported Operating System for this NUC, I remembered this thread from a user that was able to find his own solution. You may want to check it out. https://communities.intel.com/thread/43629
I also recommend to forward your inquiry to Linux* support community for further assistance since this is an operating system that we do not support.
Hi Sylvia, I was able to resolve the issue myself. It was an absented minded mistake on my part. I placed the .efi file in the MBR when it should've been placed in the EFI directory of my first partition. Once I cleared the mbr and created the file in the correct location, the host booted into Linux fine. Thanks for responding to my post.
