Lately, I have wanted to open some .exe files on my Macbook Air (Mid 2013), but that is only possible on Windows. I have downloaded Wine, which allows me to do PC things on my Mac, but sometimes, I feel I have too many downloads on my Mac at the same time and it feels cluttered for me. So, I had decided to download Windows onto my Mac. There are many different ways to do this, but I will be using Bootcamp, which is a pre-installed and simple way to download windows. You can get Windows 7 or 8, but I would recommend 7, since I have heard that 8 can be very buggy and freezes up. So, here we go. You will need a flash drive, at least 8GB.
Step 1: Bootcamp Assistant and ISO Image
First, you'll need to have a file of Windows 7. Normally, you would buy it, but you can only get it online or from re-sellers since it is about two years old. If you already own a Windows 7 physical copy, it is legal to download an ISO image online, if you don't, well... Also if you are using Bootcamp 5.0, it will only work for 64-bit ISO images. Here is a link with Windows 7 Ultimate, Professional, Home Premium, in English, Chinese, Danish, Dutch, Finnish, French, German, Italian, Norwegian, Portuguese, Spanish, Swedish, and Korean, in 32 and 64 bit ISO images (Only download the 64 bit). I would recommend Professional, since that has all the most useful features. Home Premium only has the very basic features, and Ultimate has everything, but includes a lot of unnecessary features which you probably won't use. The link is: http://www.techverse.net/download-windows-7-iso-x86-x64-microsofts-official-servers/ Click whichever ISO image you want to download and move it to the desktop of your laptop. After that you can use Spotlight, Launchpad, or Utilities to find Bootcamp Assisstant. After you have found it, open it. Click "Continue", and select the first task only, "Create a Windows 7 or later version Install Disk". After you do this, it will allow your flash drive to be bootable, or be read as a DVD in your Mac.
Step 2: Download Latest Windows Support Software
After you have finished the download from the first Bootcamp task, select quit, and re-open Bootcamp Assistant. Now, select the second task only, and download that to your flash drive. This takes about 5 minutes. Press quit, once again and you will need to re-open Bootcamp Assistant one more time.
Step 3: Remove Windows 7 or Later Version
When you re-open it again, guess what, you have to select the third task only! Big surprise there. Anyway, the task reads "Remove Windows 7 or Later Version", but after you install the first two tasks it will read "Install Windows 7 or Later Version". After the download is finished you will need to partition the 256 GB on your Macbook Air. I only gave 10 GB for Windows 7 since I only use it to open Windows specific files such as .exe and stuff. If you are going to start using it more than your Mac OS X, I would probably give it at least 100 GB or more to use. Now to begin Windows, just restart your laptop and complete the setup protocol.
Step 4: How to Switch From Mac OS X to Windows
If you want to switch between the two OS's (you can't run them both simultaneously unless you use another method), there are two ways. When you're on Mac OS X, go to System Preferences and open Startup Disk and select either Macintosh or Bootcamp Windows. Or when you restart your laptop, hold the option key, and you can choose which OS you want to run.
