I've attempted to install eOS Loki at least ten times at this pont. Everything runs smoothly up until the end when I am told to restart the computer. If I restart and remove installation media, I am told that there is no OS installed, and if I don't I am returned to the install screen. This happens with the BIOS in both uefi and legacy modes, with secure boot on or off.
you might want to run repairboot, make sure to put the bootloader in the right place: https://help.ubuntu.com/community/Boot-Repair#A1st_option_:_get_a_CD_including_Boot-Repair
