I own a NUC5i3RYH and I installed several OS (Win8.1, ArchLinux, openELEC) with USB sticks using a wireless keyboard (Logitech k400). I did not ever had a problem. I only remember that, years ago, I had problems installing Win7 on a laptop with a SSD drive, the problems were related with the old AHCI drivers, I fixed downloading the updated drivers during installation.
Said that, check your AHCI settings, the I would try with defaults first, using during boot F10 option and select exactly the media.
Another tip is to create a USB bootable using Rufus - Create bootable USB drives the easy way , I never failed an installation. Let us know.
Thank you so much for your help. I created a new bootable USB Drive using Rufus and that worked perfectly.
Happy tou fixed
