Sounds like there's issues with your boot manager. Recommend either running Startup Repair, which should repair the damaged components or re-install the OS which will replace the boot manager all together.

Regardless, since we don't know what caused this, it's recommended that you also back up your machine with a disk imager like Macrium Reflect or a snapshot tool like RollBack Rx.
