Apple's newly refreshed MacBook Air and 13-inch MacBook Pro models no longer support running Windows 7 with Boot Camp, according to Apple's Boot Camp support document. Boot Camp on the new notebooks only works with Windows 8 or later, so it is impossible to use Boot Camp to install Windows.
Why choose when you can get the best of both worlds by dual-booting? Here's how to install Windows on your Mac using Boot Camp so you can jump back and forth between the two operating systems on the same computer. What You'll Need Before you start, make sure you have enough space on your hard drive for both Windows and Mac.

We recommend at least 30GB for each, but the more space you have, the better. You'll also need a USB flash drive (4GB or larger) and a Windows 10 ISO disk image, which you can, and a valid Windows 10 license. Finally, make sure your Mac model can support Windows 10 in Boot Camp- to find out.
Install Windows 10 on Your Mac In the steps below, we'll use Boot Camp Assistant to create a bootable USB drive and install Windows 10 on a new partition. Then you'll be able to choose which OS you want to use whenever you start the Mac up.
Installing Windows 10 On Mac
Download the Windows 10 ISO disk image from Microsoft. Choose the 64-bit version of Windows. Also, some people, including myself, have gotten an error message if the ISO image is saved to your default Downloads folder, so save the ISO image to your Documents folder or somewhere else to avoid problems. Open Boot Camp Assistant. You'll find this in the Utilities folder or you can hit CMD + Spacebar to search for 'Boot Camp Assistant.' Click Continue at the Introduction screen.
Click Continue again at the Select Tasks screen. Choose the Windows ISO image and select the destination USB drive.
Note that the USB drive will be reformatted, so make sure you have a copy of any of the files on it somewhere else before proceeding. Click Continue and then Continue again.
Your Mac will format the USB drive and create the Windows installation media. Click Install to accept the partition size for each OS. By default, Windows will have a 32GB partition, but you could also click the Divide Equally button to divide your Mac's hard drive space equally between OS X and Windows. Follow the prompts to finish installing Windows. The Mac will need to restart to complete the process and will automatically boot into Windows 10 when it's done.
Set the Default Startup OS or Toggle Between OS X and Windows Once you have Windows installed, you can set the default OS that will start each time you boot your Mac. To do this, head to the Startup Disk preference setting in Settings. Every time the Mac starts, you can also toggle between OS X and Windows by holding down the Option (Alt) key immediately upon startup. RCman Says: I have the actual Win 10 CD. Do I still need to make a USB disk? I'm having the problem that I bought a 6TB drive and tried to install Windows to it in my 2nd bay.
Windows 7 On Mac
It won't install on the 2nd bay unless it can reformat the ENTIRE drive, wiping out all other partitions. I want Windows partition to only take 2tb, and use 4tb for Mac partitions and files. But Windows 10 apparently WILL NOT install on just a partition in the 2nd bay.
So I tried it another way and let Windows take the whole drive, then let WINDOWS partition it. But the new partition was turned into (free space) and inaccessible to Mac. Do I need to make the 6TB drive the BOOT drive on Mac - and THEN do Bootcamp on it? See, Bootcamp partitions the drive fine - but when I go to install Windows 10 - THAT'S what tells me it won't install here or there. And the only drives accessible for install are either a DEDICATED secondary drive - or apparently - My OSX BOOT drive - which Win10 seems to be willing to partition itself and to install into. So I can't get it on a secondary drive? It's GOTTA be on Primary Boot Drive?
Can someone help? Wen123 Says: I started Boot Camp and run until partition. Since I only had 60GB free space (not including purgeable), it allocated 43GB to Windows.
I worried that it may not be enough so hit 'Go Back' and did a few things to free up more space. When I went back to Boot Camp, it could not create boot disk on the USB. It turned out that my USB now is read only. Tried to Erase USB inside Disk Utility and tried other things like Rufus on a PC, still cannot write/Erase/Format USB. Anyone has a solution?
