No. Boot Camp 5 supports 64-bit versions of Windows 7 and 8.0 only. Boot Camp 4 supports 64-bit and 32-bit versions of Windows 7, depending on the Mac model you have. For more information, see Boot Camp: System requirements for Microsoft Windows operating systems.
Can I upgrade a previously-installed 32 bit version of Windows to 64 bit?
32-bit versions of Windows cannot be directly upgraded to 64-bit versions. You should back up your important files, then install the 64-bit version.
How can a Windows partition be resized after Windows is installed?
You need to delete the Windows partition using the Boot Camp Assistant, and start over to change the size of the Windows partition. Back up your important Windows files first.
Are upgrade installs from Windows 7 to Windows 8 supported?
Yes, but be sure to install the Boot Camp 5.0 Support Software (drivers) before upgrading to Windows 8. See Boot Camp: Frequently asked questions about installing Windows 8 for more information.
After upgrading to Windows 8, run the Boot Camp 5.0 Support Software installer again.
Can I use a downloaded (ISO) version of Windows with Boot Camp?
MacBook Air (Mid 2011 and later), MacBook Pro (Mid 2012 and later, including Retina models), Mac mini (Mid 2011 and later), and iMac (Late 2012) can install downloaded (ISO) versions of Windows 7 and 8.
To determine if your Mac supports this feature:
- Click the Go menu and choose Utilities.
- Open Boot Camp Assistant.
- Click Continue. If you see a "Create a Windows 7 or later install disk" checkbox, your Mac supports the use of downloaded (ISO) install images. See the Boot Camp Installation & Setup Guide for more information.
Do computers that come with a Fusion Drive support Boot Camp?
Yes. Use the Boot Camp Assistant to create a Windows partition and install Boot Camp. The Windows partition will exist on the hard disk drive, not the Flash drive, and is not part of Fusion Drive Logical Volume Group. 3TB Fusion Drive configurations need to update to OS X Mountain Lion v10.8.3 or later to install Windows 8. See iMac (27-inch, Late 2012): Boot Camp alert with 3TB hard drive for more information.
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.
Which application should I use to create a Windows partition and to install Windows?
Use Boot Camp Assistant (located in the Utilities folder) to create a Windows partition and to install Microsoft Windows. Boot Camp Assistant works with an Intel-based Mac that has a single hard disk partition or Fusion Drive. Boot Camp Assistant creates an additional partition for the Microsoft Windows operating system or allows you to install Microsoft Windows on another drive if you have more than one internal drive.
Boot Camp Assistant does not erase your existing Mac OS X partition or any of your OS X software when it creates a new partition for Microsoft Windows.
Important: Do not use disk utilities not created by Apple to partition the drive before using Boot Camp Assistant. Doing so may erase the entire disk.
Can I install Windows on an external drive?
No. Installing Boot Camp on an external hard drive is not supported.
Can more than one USB storage device be plugged in at Installation time?
No. You can only use one USB storage device during Windows installation. See Boot Camp: Windows installation boots to black screen with blinking cursor for more information.
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 OS X. Use the Startup Disk Control Panel in Windows or OS X Startup Disk System Preferences to set the default operating system to use each time the computer starts up.
Note: 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.
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". To resolve this issue:
- Start up to OS X and run the Boot Camp Setup Assistant again.
- Remove the Boot Camp partition and re-create it.
- Install Windows again, this time using Windows to format the partition.
- Refer to the Boot Camp Installation & Setup Guide document for more details on installing Boot Camp.
