No bootable device, hit any key

I'm an idiot. I'm also pretty new with this whole linux thing. I was tinkering about with systemd, and decided to check out the bootloader options. For some unexplicable reason i turned off secure boot, so now i can't boot into openSUSE at all and get this message. I was thinking of booting up a live distro, and just manually turn secure boot on again, but i'm not sure where to look for the option. Can someone please assist :'(

P.S. I was using UEFI, and it's openSUSE 13.1 if i'm not mistaken
