Step 8: Insert the original USB pen drive into the Mac with the bootable ISO image on it. Bear in mind that the installation itself will require approximately 30GB so choose carefully as this cannot be altered later. The Boot Camp Assistant will display the partition information and you will need to assign a portion of the drive to Windows. Step 7: The installation of Windows 7 doesn’t place nice with competing operating systems, making it necessary to create a partition on the hard drive of the MacBook Pro. Download all of the drivers that Apple provide via the Boot Camp Manager and copy the single file to a secondary USB drive (at least 1GB needed). This is particularly relevant in this instance to ensure that the full resolution of the Retina MacBook Pro is achieved in the installation.

Step 6: Anyone who has installed Windows, or even used Windows, will know that a number of drivers are required to make sure all of the hardware is functioning correctly. In the Boot Camp Manager interface, select the option to copy the file to the USB drive to create a bootable disk. Step 5: After the ISO image has been created and manually renamed, the next stage is to copy the file onto a USB drive that is greater than 4GB in size. cdr file and then manually renamed to the extension. Step 4: If you are creating the ISO image directly on the Mac using the Disk Utility process then the outputted file will need to be saved as. That ISO can then be moved across to the Retina MacBook Pro for use as part of this process. NOTE: If you don’t have access to an external drive that can be connected to the MacBook Pro, then it is possible to create an ISO disk image using one of many free of charge utilities directly from a Windows based PC. The simple Disk Utility application in Mac OS X allows a new disk image to be created from the inserted Windows DVD. An optical drive is a requirement for this process meaning that an external drive will need to be connected to the MacBook Pro.

Step 3: The next stage of the process is to create a Windows ISO image of the installation DVD. Make sure all the relevant option boxes are ticked before selecting the Continue option on the bottom right of the display. Step 2: The Boot Camp Assistant interface provides the necessary steps that are involved in installing a fully functioning version of Windows 7 on the MacBook.
