Boot Camp Control Panel User Guide

When you start up a Mac holding down the Option key, the boot volume menu appears on the screen - this shows all bootable volumes on the screen, making it simple to boot from any volume in your Mac. You can also, it turns out, set the default boot volume (the volume that will boot when you don't hold the Option key down) from this screen. You can change the startup disk your Mac automatically uses from System Preferences. From the Apple menu choose System Preferences. Click the Startup Disk icon in System Preferences, or choose View Startup Disk. Select your startup disk from the list of available volumes.

After you use Boot Camp Assistant to install Windows on your Intel-based Mac, you can set the default operating system to either macOS or Windows. The default operating system is the one you want to use when you turn on or restart your Mac.

There are several methods that you can try to eject a disc from a Mac: Press the Eject Button. Press the Eject button on the keyboard. Click the Eject Icon. Click on the Eject symbol on the menu bar at the top, then select the name of the disc drive. Drag and Drop to Eject. Click and drag the disc drive icon from the desktop into the trash bin. Change the Finder settings. One of the most common reasons for Mac not recognizing external.

Set the default operating system

1. In Windows on your Mac, click in the right side of the taskbar, click the Boot Camp icon , then choose Boot Camp Control Panel.

2. If a User Account Control dialog appears, click Yes.

3. Select the startup disk that has the default operating system you want to use.

4. If you want to start up using the default operating system now, click Restart. Otherwise, click OK.

You can’t change your startup volume to an external drive while you’re using Windows.

To learn how to change the default operating system using macOS, see Get started with Boot Camp.

Restart in macOS

In Windows on your Mac, do one of the following:

• Restart using Startup Manager: Restart your Mac, then immediately press and hold the Option key. When the Startup Manager window appears, release the Option key, select your macOS startup disk, then press Return.

  If you’re using a Mac notebook computer with an external keyboard, make sure you press and hold the Option key on the built-in keyboard.

• Restart using Boot Camp Control Panel: Click in the right side of the taskbar, click the Boot Camp icon , then choose Restart in macOS.

  This also sets the default operating system to macOS.

For more information about restarting in macOS, see the Apple Support article Restart your Mac in macOS or Windows.

An Internet Recovery requires that you have qualified hardware: Computers that can be upgraded to use OS X Internet Recovery. If yours is qualified or can be with a firmware upgrade, then do the upgrade before proceeding.

Install OS X Using Internet Recovery

Restart the computer and after the chime press and hold down the COMMAND-OPTION- R keys until a globe appears on the screen. Wait patiently - 15-20 minutes - until the Recovery main menu appears.

Partition and Format the hard drive:

Note: You will need an active Internet connection. I suggest using Ethernet if possible because it is three times faster than wireless.

This should restore the version of OS X originally pre-installed on the computer.
