To create a bootdisk for OSX Mavericks to install on a MAC that can’t do a network install, I followed these steps.

First make sure you have Install OS X Mavericks in your Applications folder, if you don’t have it, download it again from the Mac App Store.

Next, format a USB drive/flash using the Disk Utility App and the following paramters.

1. Name `Untitled`
2. Format type `Mac OS Extended (Journaled)`
3. Under Options select `GUID Partition Table`

Now you are all set to create your boot disk!

We’re going to open Terminal App and run a command to use the Apple provided createisntallmedia script, a bootable Mavericks installer.

Copy and paste the command below, it’s assumed the drive is mounted at /Volume/Untitled, but adjust as necessary.

sudo /Applications/Install\ OS\ X\ --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ --nointeraction

When you run this command, you’ll be prompted for your admin password, the script will also output progress indicators as it runs.

Create Install Media

That’s it! You now have a bootable disk for OSX Mavericks.
