I'm trying to install a copy of High Sierra in a second HD that I have connected to my computer. Everything seems to work fine and I can get through the installing process but when the computer restarts I get the message "Reboot and select proper boot device".
I still can start the computer with El Capitan OS but it's like it can't find the High Sierra installation at the other HD.
Any ideas?
