How can I install windows 8 on my MacBook Pro Retina with 2.6 GHz intel core i7 ?
MacBook Pro with Retina display, OS X Mountain Lion (10.8.2)
First update to ML 10.8.3, then you can install Windows 8 through Boot Camp Assistant and choose "Windows 7 or Later Version"
OS X 10.8.3 adds Windows 8 compatibility with Windows 8, so now you can install Windows 8.
First of all, open  > Software Update and install OS X 10.8.3. Make a backup before updating. This will update Boot Camp, adding Windows 8 support.
The rest of the steps are just the same as for Windows 7. Open Boot Camp Assistant and follow the steps. If you have Windows 8 on a disc, you have to buy an external optical drive and use it to install Windows on your computer. If you have Windows 8 on a ISO, Boot Camp Assistant will provide you help to create a bootable Windows USB drive.
