Here are the steps I took to create the bootable USB drive (I have a Mid-2014 MacBook Pro with Retina Display): Downloaded the latest OS X El Capitan (10.11.3) from the Mac App Store. Created a bootable USB drive using createinstallmedia (as explained in Apple’s documentation) and it went well. Erased Macintosh HD. Tried booting from USB drive. The macOS installer file is large with approximate size of 6 to 10GB depending upon the.

Note 3: If you get a CAN'T OPEN error, it means that you forgot to plug in your USB stick BEFORE powering on the computer, so turn the Mac off and start over from step #1.

A “startup disk” is a volume or partition of a drive that contains a bootable operating system.

You can set your Mac to automatically use a specific startup volume, or you can temporarily override this choice at startup.

  3. Use your mouse or trackpad, or left and right arrow keys to select the volume you want to use.
  4. Double-click or press the Return key to start up your Mac from the volume you selected.

If you have an optical drive connected to your computer, you can insert an installation disc to see it in Startup Manager. You can also attach FireWire or USB external hard drives that contain an operating system to add to the list of startup volumes.

Startup Manager automatically adds bootable volumes as you connect them.

  • If you’re using an external drive, make sure it’s connected and turned on.
  • Make sure you’ve installed an operating system, like OS X or Windows on the drive you’re trying to start from. Volumes that don’t contain a valid operating system aren’t listed in Startup Disk or Startup Manager.
  • If you’ve installed an operating system on a drive but it isn’t listed, the volume you’re trying to start from might need repair. If the volume contains OS X, start your computer from OS X Recovery and use Disk Utility to repair the volume, or reinstall OS X on the volume using the Recovery System.
  • Depending on the Mac you are using and the version of OS X that is installed, the Recovery System volume (Recovery HD) might not show up in Startup Manager. Press Command-R during startup to start your Mac from the Recovery System.
