Backup your files, if possible, erase the drive, and reinstall macOS.

Internet/Network Recovery of El Capitan or Later on a Clean Disk

If possible, back up your files before proceeding.

Restart the computer. Immediately, at or before the chime, hold down the (Command-Option-R) keys until a globe appears.
The Utility Menu will appear in from 5-20 minutes. Be patient.
Select Disk Utility and click on the Continue button.
When Disk Utility loads select the target drive (out-dented entry w/type and size) from the side list.
Click on the Erase button in Disk Utility's toolbar. A panel will drop down.
Set the partition scheme to GUID.
Set the Format type to APFS (SSDs, only if installing Mojave or Catalina ) or Mac OS Extended, (Journaled.)
Click on the Apply button, then click on the Done button when it activates.
Quit Disk Utility and return to the Utility Menu.
Select Install OS X and click on the Continue button.
