Boot Camp Assistant creates a partition just for Windows without erasing your existing OS X volume.
After installation, you can switch between Windows and OS X by holding the Option (Alt) key at start up. Or, use the Startup Disk control panel in Windows (installed with Boot Camp support software) or the OS X Startup Disk preference pane to set the default operating system to use each time the computer starts up.
