So you have a Mac, but you also want to run Windows? They're lucky: Shortly after the first Intel-based Macs hit the market in 2009, Apple released a tool called Boot Camp, which allows Mac owners to natively install and start their machines in Microsoft Windows. At the touch of a button, you can switch between Mac and Windows each time you start your computer.
Probably the most common reason why Mac owners use Boot Camp is playing Windows games. For example, PC MMOs such as Star Trek Online, Tera and Star Wars: The Old Republic run only on Windows. Boot Camp is also better at running Windows software than virtual machines like Parallels or VMWare Fusion, which are programs that simultaneously run Windows within the Mac operating system. Without further ado, you can set up Boot Camp and install Windows.
Check System Requirements and Buy Windows
First, you need a 64-bit version of Windows. Which version depends on the age of your Mac: The models from mid-2012 support Windows 8 and 10, while models from the beginning of 2012 support only Windows 7 and 8.
On Windows 10, you will receive a copy of the Home version either as a USB flash drive or as a download from Microsoft for $ 119. For older versions of Windows, you need to go through vendors like Best Buy.
Because different versions of Windows have different system requirements for memory, disk space, and processor speed, you should double-check that your system can comfortably run this edition. This is how it works:
- Examine the system requirements for the version of Windows you want to purchase: Windows 10, Windows 8, or Windows 7.
- Next, click the Apple menu in the top left corner and select Info This Mac .
- Compare the specifications of your Mac for processor and random access memory (RAM) with those listed under the Windows system requirements.
- If your Mac does not meet the criteria, you must select a Windows version with lower system requirements.
Make sure you have enough hard disk space available on your Mac
To use Boot Camp, you need at least 55 GB of free space on your Mac's hard drive. Boot Camp says it only needs 50GB, but Apple's own online support document recommends 55GB. Play it safe and continue with the big allocation.
- To see available space on your hard drive, click the Apple menu in the top left corner and select About This Mac
- Click Storage to see it You can see how much free space is available on your hard disk.
- If you do not have 55 GB of memory, you must first delete or transfer files. Below is a list of the best tools to free up space on your Mac.
Check for Updates and Backup
Before running Boot Camp, Apple recommends installing the latest software update and backing up important files. (Need help backing up your data? Our sister site, Macworld, has put together the best software for backing up your files.)
- Click the Apple menu in the upper-left corner, and then click App Store. Go to Updates and install all macOS software updates
- Reboot your computer when prompted. After the restart, look for software updates again until no new updates are available.
- Because Boot Camp shifts and reallocates space on your hard drive, you should back up any important data before proceeding if something gets corrupted during the process.
Time for the main event. If you have a Mac from 2015 or later, the process is a little easier. Do you have an older Mac or a copy of Windows on a DVD or flash drive? Continue with "Installing Windows on Macs Starting in 2015" or "Installing Windows from a Flash Drive or External Optical Drive".
Post-2015 Macs: Installing Windows from an ISO File
This method is probably the easiest way to install Windows, but it only works for Macs as of 2015.
- Download a 64 Bit Windows ISO from Microsoft or another licensed distributor
- Quit all open applications, and then open a Finder window. Click Applications and then go to the folder Utilities .
- Open Boot Camp Assistant then click Next
 Now select Select to the right of the ISO Image box to find your Windows ISO file.
- The next step is to partition your hard disk. You'll see a slider for your hard drive that lets you decide how much hard disk space to allocate to your Windows partition.
- Move the slider to give more or less space to your Windows partition. Keep in mind that any space you allocate will be taken from available space on your Mac, and that macOS will run more efficiently if you leave at least 30-40 GB free on its partition. Also, keep in mind that you need enough space for Windows system files, any software you want to install, and a free space buffer. (We recommend at least 5 GB of margin.)
- If you are satisfied with your partition, click Install . Your Mac may boot into the Windows setup.
- If the installation process asks for the installation of Windows, select the drive named BOOTCAMP.
- Windows will now begin the installation. You then have to make a selection for things like language, keyboard layout, and account details. It will take a few minutes for the installation process to complete.
- Finally, you reach the Windows desktop. The Boot Camp Installer should then appear in a new window. Accept the terms of the license agreement and it begins with the installation of the required drivers. After installation, you will be prompted to restart the system, click Yes .
- If you have Windows 10 installed, you should use Apple Software Update to prevent known drivers problems. Make sure you are connected to the Internet, and then click Start at the bottom left and open Apple Software Update . Bootcamp Installer ” width=”300″ height=”243″ data-imageid=”100765328″ data-license=”IDG”/> IDG
- In the box above, select all available updates, and then click Install items . (If you wish, you can also install New Software such as iCloud.) Windows asks if Apple Software Update should make any changes, click Yes ] After the installation is complete, You will be prompted to restart. Click OK and your Mac should now reboot in a fully functional version of Windows 10!
To switch between your Mac and Windows partition, hold down the  option key during a boot or reboot sequence to access the OS selection menu open
Install Windows on Pre-2015 Macs
While Macs before 2015 can still run Windows, the installation process is a bit more complex. The simpler method (and our preferred option) is to use the Boot Camp Assistant, but you can also choose from a flash drive or a disc.
Run Boot Camp Assistant
- Quit all open applications, and then open a Finder window. Click Applications and then go to Utilities .
- In the Utilities folder, double-click Boot Camp Assistant to start. Click Next to start setup
- Make sure Download the latest Windows support software from Apple down. With this software you can install the latest drivers for Windows. Now click Next .
- If you are prompted for your administrative credentials, complete them. Then press Enter to start downloading the software. You need to install the Windows support software on a USB drive that you have connected to the Mac.
- After the download is complete, the wizard prompts you to create a Windows partition on your hard disk. This action will segment your drive so that it releases free space for Windows only, without disturbing or deleting your existing macOS installation.
- Here's a slider for your hard drive. Here you can decide how much hard disk space you want to allocate to your Windows partition.
- Adjust the slider so that your Windows partition is more or less free. Keep in mind that any space you allocate will be taken from available space on your Mac, and that macOS will run more efficiently if you leave at least 30-40 GB free on its partition. Also, keep in mind that you need enough space for Windows system files, any software you want to install, and a free space buffer. (We recommend at least 5 GB of margin.)
- If you are satisfied with your partitioning scheme, click Partition . OS X starts partitioning and rearranging your hard drive data, a process that can take some time.
Installing Windows from flash drive or external optical drive
This method takes a bit of patience, so bear with us. (A simpler alternative is to use ISO management software, such as Toast Titanium, to mount a downloaded Windows ISO without a flash drive or DVD.)
- Insert your Windows installation DVD into an external USB optical drive. Or, if your version of Windows came with a flash drive, paste it.
- If the media appears in the Finder, press Go and then select Utilities > Disk Utility .
- In Disk Utility select the USB optical drive or flash drive to be highlighted ,
- Under ] file, select New Image and select the Windows DVD or flash drive.
- From the Image Format menu, select DVD / CD and select None for encryption
- Save the file with a name and enter your username and password when prompted. A progress bar will appear and may take a while to complete.
- When saving is complete, eject the Windows DVD or flash drive. If you are using an external USB drive, disconnect it after ejecting the DVD.
- Use Finder to search for the disk image stored in step 6. Just click on it once to select it. Enter to rename the file. You should rename it in the end with the file extension ".iso". A window appears where you should select "Use .iso".
- Back to Applications > Utilities and then Boot Camp Assistant . Make sure that the following check boxes are selected: Create an installation CD for Windows 8 or later ; Download the latest Windows support software from Apple ; and Install Windows 8 or later version .
- Locate your renamed ISO file when prompted and click OK to start installing Windows to start.
