I recently purchased a Samsung ATIV Book 6 laptop, and swapped out the hard drive for a Samsung SSD 840 PRO Series (512 GB). Unfortunately, I can't seem to boot off of it. On the main BIOS screen, it's clearly recognized as the device plugged into the SATA Port 1. However, over at "Boot Option Priorities" where you specify the boot order, the page is entirely blank showing no options (i.e. no devices).
When I boot up with a bootable USB stick, it gets recognized fine. I've created a GPT, installed Gentoo with no issues whatsoever. However, after unmounting it and rebooting the computer, the problem persists.
I think it's weird that the BIOS doesn't list the SSD as a bootable device and does not try to boot from it, and yet it can be mounted without any problems and written to / read from. I think it's even weirder that in spite of not being listed as a bootable device, it gets recognized by name as the device plugged into the SATA port 1. Does anyone have any ideas on how to solve this?

Missing from boot order
Here's the boot order with a flash drive plugged in
Both of those are the flash drive…
