Solution 1:

(From OS X Daily)

You'll need an 8 GB or larger USB Drive. Remember, it will be erased, so backup any important files.

Use the following command in Terminal (assuming the Install OS X El Capitan app is in /Applications, which where the App Store installs it by default)

Also make note of the USB Volume Label and use its name in the command below in place of: <USB_Volume_Name>

sudo /Applications/Install\ OS\ X\ El\ Capitan.app/Contents/Resources/createinstallmedia --volume "/Volumes/<USB_Volume_Name>" --applicationpath /Applications/Install\ OS\ X\ El\ Capitan.app --nointeraction
