"Reboot and select proper boot device"- tried nearly all suggestions

[Aazers]

So I recently tried to use my old desktop which I haven't used for about six months, but unfortunately I keep getting the "reboot and select proper boot device" error. I have three bootable things: a Samsung SSD, a DVD drive, and a Western Digital HDD which is weirdly not showing as a bootable device. I'm pretty certain I installed Windows 7 on the SSD a long time ago, and as far as I can remember the computer had been working when I stopped using it, but now for some reason I'm getting this error. I set the bios order to boot from the ssd first, I disabled secure boot, I set boot mode to legacy only, but I can't figure this out. My motherboard is a gigabyte z87x-ud3h if that helps. I'll try to post a picture in a bit of my bios as well as my Sata connections, if that will help.
