I've run into a frustrating issue with my PC. It was working perfectly fine yesterday, but now I can't get past the BIOS screen because it says there's no bootable device. I tried enabling CSM, but it just tells me to reboot and select a proper boot device or insert boot media. How could this happen, and what steps can I take to fix it?

If your operating system or boot manager got corrupted, you may need to reinstall the OS. The tricky part is if you're stuck in BIOS, you might need to create a bootable USB on another machine to get started. After that, you can reinstall from there.
It sounds like your boot drive might have failed. If your PC can’t boot, it’s often because the drive it normally uses to start up isn't functioning anymore. Since it could still be detected, it might be worth checking the connection or trying a different port if you can.
Make sure your storage drives are recognized in the BIOS. The reason for enabling CSM is often to support older devices, but if it's not helping, there might be another issue. You said it shows all three of your hard drives, so that’s a good sign. Just make sure you have the right drive set as your primary boot device.
