1. What is Boot Camp?  

Boot Camp is software included with OS X Lion and Mountain Lion so you can run compatible versions of Microsoft Windows on an Intel-based Mac.

2. What is new in Boot Camp 4.0?

  • Electronic Software Distribution
    Use the Boot Camp Assistant to create a CD or USB media to install the latest Boot Camp drivers for your computer. You should get the newest drivers available any time you install Boot Camp.
  • Support for the Windows 7 ISO installer
    Install Windows with an installation disc you provide or, on Mac computers that do not have an optical drive, with a USB flash drive that contains a Windows 7 ISO image downloaded from Microsoft. The Boot Camp Assistant will offer to create this image on supported computers.
  • Upgrade or "clean" install Windows without using the Boot Camp Assistant
    If you want only to upgrade the version of Boot Camp or Windows on your Windows partition, you don’t need to use Boot Camp Assistant. Instead, choose Help > Help Center in Finder and search for “upgrade Boot Camp” or “upgrade Windows.” 

Installation and partitioning questions

3. Which versions of Windows work with Boot Camp 4.0?

You can use Microsoft Windows 7 Home Premium, Microsoft Windows 7 Professional, or Microsoft Windows 7 Ultimate with Boot Camp 4.0. Windows XP and Windows Vista are not supported with Boot Camp 4.0. 

4. Does Windows 8 work with Boot Camp 4.0?

Microsoft Windows 8 is supported with Boot Camp 5. See Boot Camp: System requirements for Microsoft Windows operating systems for more information.

5. Are 64-bit versions of Windows 7 supported?

Yes. Learn more about the Mac computers that support 64-bit versions of Windows 7.

6. I have a Mac Pro with a Mac Pro RAID card (Redundant Array of Independent Drives); can I install Boot Camp on my Mac Pro?

Boot Camp does not support the installation of Windows onto a Mac using a Mac Pro RAID card or software RAID.

7. Which application should I use to create a Windows partition?

Use Boot Camp Assistant (located in the Utilities folder) to create a partition for Microsoft Windows. Boot Camp Assistant works only with an Intel-based Mac that has a single hard disk partition. Boot Camp Assistant creates a second partition on your existing startup disk for the Microsoft Windows operating system, or allows you to install Microsoft Windows on another drive if you have more than one internal hard drive installed.

Boot Camp Assistant does not erase your existing partition or existing Mac OS X installation when it creates a new partition for Microsoft Windows.

Important: Do not use disk utilities not made by Apple to partition the drive before using Boot Camp Assistant. Doing so may erase the disk.

8. If I have more than one hard drive, can I install Microsoft Windows on any drive?

You can use Boot Camp to install Windows on any internal hard drive, but not on an external hard drive.

9. I have a wireless mouse and keyboard, but they don't seem to respond when I try to select a partition or type an account name during Windows installation. What is happening?

The drivers for your wireless mouse and keyboard are not installed yet, so you cannot use them. You need a wired mouse and keyboard to install Windows. When your installation is complete, install the Windows drivers from the CD or USB media that were created when you initially ran the Boot Camp Assistant. This should resume full function of your wireless keyboard and mouse.

Startup questions

10. How do I choose which operating system will start up my Mac?

After running Boot Camp Assistant and installing Microsoft Windows and Boot Camp drivers, press and hold the Option (Alt) key while you start up your Mac to switch between Microsoft Windows and Mac OS X operating systems. Use the Startup Disk control panel in Windows or Mac OS X Startup Disk preferences to set the default operating system to use each time the computer starts up.

11. What can I do if my computer starts up to a black screen with white text that says "No Boot Disk Attached"?

This message means that the Windows partition cannot start up, usually because of an issue with the drive formatting. The Boot Camp Setup Assistant creates the Boot Camp partition, but the Windows installer must format it to make it "bootable".

  1. Start up to Mac OS X and run the Boot Camp Setup Assistant again.
  2. Remove the Boot Camp partition and re-create it.
  3. Install Windows again, this time using Windows to format the partition.

Refer to the Boot Camp Installation & Setup Guide PDF document for more details on installing Boot Camp.

12. Why doesn't my external FireWire, USB, or Thunderbolt disk appear in the Microsoft Windows Startup Disk control panel?

External FireWire, USB, and Thunderbolt disks are not recognized by the Startup Disk control panel in Microsoft Windows. To start up from a bootable external drive, press and hold the Option (Alt) key while the computer starts up, then select the external disk.

15. Why don't CDs and DVDs eject using the Eject key on my Apple keyboard when running Microsoft Windows?

The Apple Keyboard Eject Key software may not be installed; make to install the Windows support software (drivers) as described above and in the Boot Camp Installation & Setup Guide PDF.
