For starters, OS X Recovery doesn’t include the full Mavericks installer—it requires you to download over 5GB of data before you can reinstall OS X 10.9—whereas a bootable installer drive contains all the necessary data, making installation much, much faster. For example, if you want to install Mavericks (OS X 10.9) on multiple Macs, a bootable installer drive is faster and more convenient than downloading or copying the entire OS X installer to each computer.But even for troubleshooting, a bootable installer drive has advantages over OS X Recovery.

Instead, you’ll mount it using Terminal, which makes it visible in Disk Utility. Unfortunately, BaseSystem.dmg is invisible, and because this is a read-only volume, you can’t make BaseSystem.dmg visible. In Disk Utility, find this destination drive in the left sidebar. Connect to your Mac the properly formatted hard drive or flash drive you want to use for your bootable Mavericks installer. Drag the BaseSystem.dmg icon into the Source field on the right (if it isn’t already there). Wait for the restore procedure to finish, which should take five to ten minutes. Click Restore, and then click Erase in the dialog box that appears if prompted, enter an admin-level username and password.

(If you don’t do this, you have two mounted volumes named OS X Base System—the mounted disk image and your destination drive—which makes the next step more confusing.) This action unmounts the disk image named OS X Base System.
