Downloading the OS X Mavericks Installer from the OS X Yosemite App Store

To be able to find the Mavericks installer app, you must have downloaded it at some point with the same Apple ID you are using to access the App Store. If you never previously downloaded it or installed it on a Mac, you will not find the installer available on that account.

Go to the  Apple menu and choose “App Store”

Click on the “Purchases” tab and log in to your Apple ID if you haven’t done so already
Scroll through the list of purchased / downloaded apps and find “OS X Mavericks”, then click the “Download” button next to its name

How to Create an OS X Mavericks USB Installation Drive

Download OS X Mavericks from the Mac App Store, if you haven't already. If it tries to start the installation, just close it.

Insert your USB drive (you'll need one that's 8GB or larger) and open Disk Utility.

Select your drive in the sidebar and go to the Erase tab. Format the drive as "Mac OS Extended (Journaled)" and name the drive "Untitled." (Note: if you already have a drive or partition named "Untitled" connected to your computer, name it something else and change the corresponding variable in step 5's terminal command, or you might experience data loss!).

Click the Erase button and wait for Disk Utility to finish.

Close Disk Utility and open up a Terminal window. Copy and paste the command into the Terminal.

Run this in terminal and wait about 20 minutes:

sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ Mavericks.app --nointeraction

You should see something like this:

Erasing Disk: 0%... 10%... 20%... 100%...
Copying installer files to disk...
Copy complete.
Making disk bootable...
Copying boot files...
Copy complete.
Done.

so don't cancel it or eject your USB drive while it's doing its thing.

When it's done, you should get a message stating the process is finished. Now, you can restart your computer, hold the Option key to access the boot menu, and select your new USB drive. From there, you can launch disk utility, format your drive, and do a clean install of Mavericks.
