How to make boot disk for MacBook Pro with Mavericks pre-installed

Question

Hi -
I recently bought a new 15" MacBook Pro with Retina Display, which came pre-installed with Mavericks (10.9.0).  I want to make a bootable USB disk of the system software, and have successfly used DiskMaker X (formerly Lion DiskMaker) to make the USB boot disks for Lion and Mountain Lion.  In those cases, however, I was running earlier versions of the OSX, and downloaded the new OSX version -- Lion and Mountain Lion -- from the App Store in order to make to make the disk.  In this case, however, Mavericks was pre-installed, and I was unable to download it from the App Store (an alert said that it couldn't be installed on this computer... presumably because it was already installed).  I would apprecite any suggestions as to how I can create the boot disk without the ability to download Mavericks.  Thanks very much for any help anyone can provide.

Answer 1

Open App Store and locate the full installer download file (5.29 GBs) for 10.9.1. Download to your computer.
Make Your Own Mavericks, Mountain/Lion Installer
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:
Open Disk Utility in your Utilities folder.
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.
Select the volume you just created (this is the sub-entry under the drive entry) from the left side list.
Click on the Erase tab in the DU main window.
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.
Click on the Erase button. The format process can take up to an hour depending upon the flash drive size.
    3. Use DiskMaker X to put your installer clone onto the USB flash drive.
Make your own Mavericks flash drive installer using the Mavericks tool:
You can also create a Mavericks flash drive installer via the Terminal. 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.
