If you have already installed Windows 10, Windows 8.1, Windows 8, or Windows 7 on your Mac using Boot Camp, you can set Parallels Desktop to run Windows from the Boot Camp Partition or import Windows and your data from Boot Camp into Parallels Desktop as a new virtual machine. Alternatively, you can insert your Mac installation disc to download these drivers (this may depend on if your Mac came with Lion or Snow Leopard and the type of Mac you have). Step 6: After you installed the Windows compatibility driver software, go ahead and create a Windows partition.
This is Step 4 (page 8). Perhaps you should read it again.
Step 4: Install the Windows Support Software After installing Windows, install Mac-specific drivers and other support software for Windows. The support software installs Boot Camp drivers to support your Mac’s hardware, including AirPort, its built-in camera, the Apple Remote, the trackpad on a portable Mac, and the function keys on an Apple keyboard. The software also installs the Boot Camp control panel for Windows and the Apple Boot Camp system tray item.
To install the Windows support software:
1 If you can’t find the CD, DVD, or external disk with the support software you downloaded, open Boot Camp Assistant and download the software again.
You can quit the assistant after you save the software without creating a new partition.
2 Insert the CD or DVD or connect the external disk with the Windows support software.
The installer may start automatically. If it doesn’t, do one of the following:
If the support software is on the same USB flash drive as the Windows 7 installer, double-click the setup.exe file in the WindowsSupport directory.
- Otherwise, double-click the setup.exe file in the Boot Camp directory.
3 Follow the onscreen instructions.
Important: Do not click the Cancel button in any of the installer dialogs.
If a message appears that says the software you’re installing has not passed Windows
Logo testing, click Continue Anyway.
You don’t need to respond to installer dialogs that appear only briefly during the installation.
If nothing appears to be happening, there may be a hidden window that you must respond to. Check the taskbar and look behind open windows.
4 After your computer restarts, follow the instructions for any other installers that appear.
5 Check for updated Windows support software by using Apple Software Update or going to www.apple.com/support/bootcamp.
