Feb 12, 2016 6:33 AM in response to wecarby mende1,If you want to know how to make a OS X El Capitan installer USB drive, there are third-party apps that let you do it like DiskMaker X -> http://diskmakerx.com/ You only have to download OS X El Capitan from the App Store before running the app, and you need a USB drive with enough space to store the OS X El Capitan installer.

Feb 12, 2016 6:45 AM in response to wecarby Lanny,Since you should (certainly recommended) have a backup of your system on an external drive, make it a clone backup, then you wouldn't need to make USB dongle. You could also just keep a copy of the latest installer on your drives so that you wouldn't need to download it again.
