I just installed windows with boot camp. How do I run it?
My laptop just opens with MacOSX and the partition that has the windows files in it appears on my desktop like an external drive.
Reboot, once you hear the startup chime (make sure your volume is on in OS X) hold down the "option" key/ "alt" key until both disks appear on screen. You can then use the arrow keys to toggle back and forth from OS X to Windows, and use enter to select.
In order to always boot into Windows, go into System Preferences (or control panel in Windows) and select startup disk (boot camp in Windows), authenticate, and click on the Windows startup disk (click the startup tab in Windows, and follow the same instructions).
Very simple, and posted many many times before.
