    Creating a bootable OS X Mavericks USB installer


First, plug in an 8GB (or bigger) USB drive, and use Disk Utility to erase it
If you use the default settings, you should wind up with a blank drive at /Volumes/Untitled.

With that volume in place, and with the Mavericks installer sitting in /Applications/Install\ OS\ X\ Mavericks.app,
run the following command in your terminal to create a bootable install media:
sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ Mavericks.app --nointeraction
You should see output like the following—it might take a while to finish.
Erasing Disk: 0%... 10%... 20%...100%...
Copying installer files to disk...
Copy complete.
Making disk bootable...
Copying boot files...
Copy complete.
Done.

To boot from the installer, reboot your Mac and hold down the alt/option key, and it will let you
choose to boot from the USB disk.
Enjoy!
