Archived - Boot Camp: Restarting into Mac OS X using the command line

When running Windows on a Mac using Boot Camp, the startup disk can be changed using a command line, in addition to the Startup Disk Control Panel.

This article has been archived and is no longer updated by Apple.

Note: This command requires Boot Camp 3.0 or later (beginning with Mac OS X v10.6 Snow Leopard).

  1. Boot the Mac using Windows.
  2. Click on Start.
  3. Click on All Programs.
  4. Click on Accessories. 
  5. Click on Command Prompt.
  6. Type in the following command:
    c:\progra~1\Bootca~1\bootcamp.exe -StartupDisk "Mac OS"
    Shutdown /r /t 0
  7. The computer will restart into Mac OS X.

Note: BootCamp.exe -StartupDisk <VolumeName> - Bootcamp.exe has a command line option ‘-StartupDisk <VolumeName>’ to set the Startup Disk.  When the Mac is rebooted, it will boot to the volume specified by <VolumeName>.  If <VolumeName> is omitted, then the system will boot into the first Mac OS X volume located by BootCamp.exe.  Bootcamp.exe is located at “c:\Program Files\Boot Camp\BootCamp.exe.”
