How can I fix no Bootable device

Sometimes, a no bootable device error means a failed hard drive or SSD. Since this laptop is only 5 years old, I would doubt this as the cause of the error, though. This would usually be due to a software problem at this time. This could be due to bad BIOS settings (rapidly click F12 on startup), a bad boot order (go into BIOS settings and then boot order), a loose connection, or corrupted files on the SSD.
