    Did you partition and format the flash drive first? See the following:

     

    Make Your Own Mavericks, Mountain/Lion Installer

     

    1. After downloading the installer you must first save the Install Mac OS X application. After the installer downloads DO NOT click on the Install button. Go to your Applications folder and make a copy of the installer. Move the copy into your Downloads folder. Now you can click on the Install button. You must do this because the installer deletes itself automatically when it finishes installing.

      

       2. Get a USB flash drive that is at least 8 GBs. Prep this flash drive as follows:

     

    1. Open Disk Utility in your Utilities folder.
    2. After DU loads select your flash drive (this is the entry with the mfgr.'s ID and size) from the leftside list. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
    3. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list.
    4. Click on the Erase tab in the DU main window.
    5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
    6. Click on the Erase button. The format process can take up to an hour depending upon the flash drive size.

     

    Make your own Mavericks flash drive installer using the Mavericks tool:

     

    Mavericks has its own built-in installer maker you use via the Terminal:

     

    You will need a freshly partitioned and formatted USB flash drive with at least 8GBs. Leave the name of the flash drive at the system default, "Untitled." Do not change this name. Open the Terminal in the Utilities folder. Copy this command line after the prompt in the Terminal's window:

     

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

    Press RETURN. Enter your admin password when prompted. It will not be echoed to the screen so be careful to enter it correctly. Press RETURN, again.

     

    Wait for the process to complete which will take quite some time.

    You don't format a drive as GUID. You partition them using GUID, then format them Mac OS Extended, Journaled. If the latter isn't used then it will not boot the system properly or at all. Be sure you used at least an 8 GB flash drive.

     

    The Mac OS X Installer Mavericks full download must be located in the Applications folder.

    You can make a bootable USB stick to install using this free program. It does all the work for you.

    Sorry, Eric, it won't work if you use it while running Snow Leopard.

    If you say so, but when I downloaded Mountain Lion, I ran the program, then called LionDiskMaker, in Snow Leopard and made a bootable USB of Mountain Lion before I installed it. Of course it is a different program now, so you are probably correct. If I was the OP, I'd make a copy of the installer and store it outside the Applications folder, install Mavericks, and then run the program.

     

    Happy Birthday.
