Reinstall El Capitan or Later Without Erasing Drive


Please be sure you back up.


  1. Restart the computer. Immediately after the chime hold down the Command and R keys until the Utility Menu appears.
  2. Select Disk Utility and click on the Continue button.
  3. Select the indented (usually, Macintosh HD) volume entry from the side list.
  4. Click on the First Aid icon in the toolbar. Wait until the Done button activates, then click on it.
  5. Quit Disk Utility and return to the Utility Menu.
  6. Select Install OS X and click on the Continue button.


If the above is unsuccessful then do the following:


Install El Capitan or Later from Scratch


If possible backup your files.


  1. Restart the computer. Immediately after the chime hold down the CommandandRkeys until the Apple logo appears. When the Utility Menu appears:
  2. Select Disk Utility from the Utility Menu and click on Continue button.
  3. When Disk Utility loads select the volume (indented entry, usually Macintosh HD) from the Device list.
  4. Click on the Erase icon in Disk Utility's main window. A panel will drop down.
  5. Set the Format type to APFS (SSDs only) or Mac OS Extended (Journaled.)
  6. Click on the Apply button, then wait for the Done button to activate and click on it.
  7. Quit Disk Utility and return to the Utility Menu.
  8. Select Install OS X and click on the Continue button.


This will install the version of OS X you had installed.

What are those two ghosted indented entries? I don't read your language, so translate, please. Your second image looks like you reformatted the SSD but no volume entry.
