Stuck in Aptio Setup Utility

Jun 6, 2018
I have an ASUS Q503u Notebook. I have not been able to get beyond the Aptio Setup Utility all day! I've searched fixes and tried all of what I've found so far, with no success. The "launch csm" route isn't it takes me to a screen asking me to "reboot and select proper boot device or insert boot media" before i can get to any recovery screen... I also made sure the HDD was properly connected. The HDD is also making a weird noise, kinda like a soft sizzling, crackling sound. Computer was working just fine earlier today...hasn't been dropped or exposed to any extreme conditions. Any help?
