I'm starting to have issues booting up after shutting down or restarting my PC. Every time I shut down i'm prompted with "reboot and select proper boot device". I always keep it on sleep so i'm not exactly sure when this problem started. I can boot up but only after I go into BIOS and change my boot priorities BUT somehow even after I changed the boot priorities this problem still persists unless I repeat what I did previously. Is this a bios problem? It's not exactly up to date but I never had any issues like this before.
