Repair a storage device in Disk Utility on Mac
Disk Utility can fix certain disk problems—for example, multiple apps quit unexpectedly, a file is corrupted, an external device doesn’t work properly, or your computer won’t start up. Disk Utility can’t detect or repair all problems that a disk may have.
If you run First Aid on a disk, Disk Utility checks the partition maps on the disk and performs some additional checks, and then checks each volume. If you run First Aid on a volume, Disk Utility verifies all the contents of that volume only.
If your Mac has a Fusion Drive and you see a flashing question mark or alert, see the troubleshooting section of the Apple Support article About Fusion Drive, a storage option for some Mac computers.
If you continue to have problems with your disk or it can’t be repaired, it may be physically damaged and need to be replaced. For information about servicing your Mac, see Find out how to service or repair your Mac.

It actually means the start up volume cannot be found, that could be a dead or dying HD. Please try holding down the Option key on start up first and if your start up volume appears please select it. If it boots okay, then open System Preferences - Startup Disk and select the start up volume. If that does not work, then please follow BD Aqua’s sound Advice.
Any luck yet?
