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.
Note: This command requires Boot Camp 3.0 or later (beginning with Mac OS X v10.6 Snow Leopard).
- Boot the Mac using Windows.
- Click on Start.
- Click on All Programs.
- Click on Accessories.
- Click on Command Prompt.
- Type in the following command:
c:\progra~1\Bootca~1\bootcamp.exe -StartupDisk "Mac OS"
Shutdown /r /t 0
- 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.”
