First, the preparatory work:
1. Prepare a USB flash drive with 8GB or more capacity to ensure that the data is properly backed up (this process erases all data on the USB stick)
2. "Install OS X El Capitan" in your application folder which has just been downloaded from the official website
I am speaking here is the official version, not beta OS X EI Capitan, this official version you open the App store can download


Second, formatted USB flash drive (3.0 USB Pro test available)
1. Insert your USB drive, and then locate and open the disk utility in the Application "->" utility
2. Find the name of the USB flash drive in the left list and click
3. Select "Partition" at the top of the right and select "1 Partitions" in "Partition Layout"
4. In the partition information "name" Input "capitan" (because this name will be used in the following command, if you want to change to another (English), be sure to correspond to modify the following command)
5. In "format" select "mac OS Extension (journaled)"
6. At this point, do not rush to the "application", but also first in the "Options", select the "guid partition table"
7. Start formatting


Iii. input Terminal command to start the production of startup disk
1. Make sure that the file named "Install OS X El Capitan" is saved in the "Application" directory
2. Find "terminal" in "Application"->"utility" and open it. You can also open it directly via Spotlight search "terminal"
3. Copy the following command and paste it into "terminal" and press ENTER to run:
------command starts------Copy from sudo (do not copy this sentence)


Sudo/applications/install\ os\ x\ el\ capitan.app/contents/resources/createinstallmedia--volume/volumes/capitan-- Applicationpath/applications/install\ os\ x\ el\ Capitan.app--nointeraction


------command ends------to nointeraction (do not copy this sentence)
Command Description:
Install\ os\ x\ el\ Capitan.app This is the official version of "Install OS X El Capitan" in the correct location
Capitan This is the name of the USB drive.


After entering, you will be prompted to enter the administrator password, the next step is to wait for the system to start making the boot disk. At this point, you will see a message similar to the following in the command execution:
Erasing disk:0% ... 10% ... 20% ... 30% ... 100% ...
Copying installer files to disk ...
Copy complete.
Making Disk Bootable ...
Copying boot files ...
Copy complete.
Done.

When you see the end of the "copy complete" and "done" words appear is that the boot disk has been made!

When you insert a completed OS X El Capitan USB boot disk, the desktop appears "install OS X el capitan" drive letter, then it means the boot disk is normal.

So how to do a new system installation via USB boot?

In fact, it is very simple, first insert the USB flash drive on the target computer, then restart your Mac, and then press and hold the "option" (ALT) button until the screen shows the option of a USB boot disk.

Then select the USB flash drive icon to enter, you can install OS X El Capitan by USB stick! At this point, you can directly overwrite the installation system (upgrade), or you can format the disk tool to erase the entire hard disk, or re-partition to achieve a clean installation.
