BootCamp Assistant is an application made by Apple that makes it easy to install and run Windows on a Mac.  It’s not absolutely necessary to use the BootCamp Assistant however it does somewhat simply the process. It does this by automatically creating a separate partition on your hard drive and then uses that partition to run Windows on the Mac. The steps taken by BootCamp to install Windows on a Mac can also all be accomplished by using Disk Utility so we’ll go through both methods.

Understanding the Basics

Understand BootCamp

BootCamp Assistant does two things, it downloads all the drivers necessary for Windows to operate properly and makes it easy to partition your hard drive into 2 partitions. One partition will be used by your Mac to run Mac OS X and the other partition will be used to run Windows.

Basically what the drivers do, is allow your built-in camera, special keyboard function (like volume), magic mouse and trackpad to work properly. For example, without the drivers, when you press the volume button on your Apple keyboard it won’t do anything because there are no driver to tell Windows what that button does. The Windows support drivers should be installed even if you don’t plan on using the built-in camera or any of the other Apple hardware. It basically helps your Mac run Windows properly.

Next, why do I have to make a new partition to install Windows? Well the reason is that Windows and Mac don’t run on the same format. Macs run on Mac OS X (Journaled) and Windows runs on NTFS. Partitioning splits your hard drive into 2 separate sections, each with its own format. This means that your Mac will continue to run on Mac OS X (Journaled) and Windows will be able to run on NTFS. Think of it this way, the soon to be roommates both live in the same house but each get their own room customized to their own liking.

It’s not necessary to use BootCamp Assistant since it can all be done with Disk Utility, however I’ll go through that at the bottom of this article.

Preparing your Hard Drive with BootCamp

Partition with BootCamp

Whenever you do anything to modify the hard drive you should alwaysmake a backup first; it’s very unlikely that something will go wrong but best be on the safe side. After making a backup, open BootCamp, it can be found in the Applications/Utilities folder or by searching for it in spotlight.

Here you will see the options that allows you to “Download the latest Windows support software from Apple” and “Install Windows 7 or later version”.

Lets handle downloading the latest Windows support software first. BootCamp assistant wants you to download the support drivers directly onto a properly formatted USB flash drive. If you go this route, your USB drive has to be formatted as MS-DOS (FAT), this is because Windows can not read the default Mac format. It’s not necessary to go this route as the support drivers can be downloaded directly from the Apple website, even after you’ve installed Windows on your Mac.  I’ve already covered how to format a drive, read the guide here if needed: Formatting a Drive

If you’d rather skip this step, just uncheck “Download the latest Windows support software from Apple”. Once you’ve got Windows installed on your Mac, it can be downloaded from BootCamp Recent Software Updates.

Next, onto partitioning the hard drive. Well first, it’s not always necessary to partition your drive. If you have more than one internal hard drive, and want to use it solely for Windows then there is no reason to partition it. Simply format it during the Windows installation. The same thing goes for an external hard drive that you want to use solely to run Windows on your Mac.

If you do want to partition your drive, BootCamp makes it really easy to do. It show two sections on the partitions page, OS X and Windows. Just drag the slider left and right to decide on how much space you want to dedicate to the Windows partition. For a bare minimum you should at least dedicate 20GB. It depends on what you want to do with this partition however. If you’re a gamer and plan on installing many games, you should probably dedicate more that 20GB to Windows. I’d recommend around 60GB-100GB, however it depends entirely on how you plan to use Windows on your Mac.

Once you’ve decided on the amount of space you’d like to dedicate to Windows click the “Install” button. BootCamp Assistant will immediately start partitioning your drive. It usually takes around a minute to complete. Next your Mac will restart. Make sure your Windows install disk is inserted as it will be needed right after the restart.

Installing Windows on a Mac

Installing Windows 8

Once your Mac restarts, it will load up the Windows installation files. Be patient, it can take a while, for me it took around 3 – 4 minutes. Once the install files are booted up, the first thing you’ll have to do is agree to the terms and conditions, after reading the 25 page policy of course…

Next, you’ll be presented with two options, Upgrade or Custom. ChooseCustom: Install Windows only (Advanced).

In the next screen all the partitions on your Mac will be shown. If you used BootCamp the drive will be named BOOTCAMP. Select the drive that you’re going to install Windows on, double-check to make sure it’s the correct drive. Windows will show, “Windows can’t be installed on Drive 0 partition 4″. This is because BootCamp wasn’t able to format the drive to NTFS (this is normal). So we need to format this drive to NTFS, luckily it’s really easy.

After you’ve selected the correct drive, click “Drive options (Advanced)”. A little menu with the option to format will appear. Click on “Format”, once done, click “Delete”. Within a couple of seconds the drive will be formatted to the Windows NTFS format. The partition/drive will now be labelled, “Unallocated”, which is what we want. Now that it’s formatted, all that remains to be done is to simply click the “Next” button and Windows will start to be installed.

The entire process should take about 30-40 minutes on a regular drive, and will automatically restart multiple times during the process.

After it’s all complete and you’ve setup your user account (Windows will walk you through it), the BootCamp support drivers will need to be installed. Simply use the support software downloaded earlier or download it now from the Apple website and install it.

Install Windows on a Mac without BootCamp

Partition or Format

Installing Windows on a Mac without BootCamp is pretty much the same thing as installing it with BootCamp. For instance, the only thing BootCamp really did was download the support drivers and then partition the drive.

To do it without BootCamp simply open Disk Utility and select the drive you want to partition. Once selected, click the partition tab and then the little “+” symbol. Decide on the size of the partition, give it a name and choose a format. I suggest MS-DOS (FAT), however it doesn’t really matter as you are going to format it to NTFS later on when going through the Windows install process. Next simply restart your computer with the Windows installation disk inserted.

If Windows does not automatically start up when you restart your computer hold down the “Options” key when your Mac restarts/starts up. This will bring into view all the media attached to your Mac. Simply select the Windows installation disk and off you go.

Step 1 of 3 – Preparation

Show Package Contents

Firstly you actually have to have the OS X Mountain Lion install app downloaded, you can purchase it from the Mac App Store. Once Mountain Lion has been downloaded, you’ll be able to find it in your Applications folder.

If the downloaded Mountain Lion app automatically pops up after downloading, don’t install it yet, just close the window. What we’re looking for is a DMG file. Go to your Applications folder and locate the “Install OS X Mountain Lion” app.  Right click it and select “Show Package Contents”. Once opened there’ll be a folder called “Contents”, open it, and finally open the “SharedSupport” folder. Inside this folder there should be 2 files, one called “InstallESD.dmg” and the other “OSInstall.mpkg”, copy the InstallESD.dmg to the Desktop. This will be the file that we’ll be using to create the bootable disk image onto the USB Flash drive.

Step 2 of 3 – Prepare the USB Flash drive

Format USB drive

To create the bootable disk image, your UBS drive has to have at least 8GB of storage. Nowadays USB Flash drive are really cheap and can be purchased at almost any electronics store (the Flash drive I use is 16GB and only cost $15). Plug it into your Mac, and launch Disk Utility (located in Applications/Utilities). We’re going to format the USB drive, so make sure there isn’t anything on it that you need, as formatting will erase everything on the USB drive.

Select the USB drive that is to be formatted, then select the Erase tab. Under the selection for “Format:” select “Mac OS Extended (Journaled)“, and name it anything you’d like. It would probably would be best however to make it something recognizable like “Mac Install” or “Mountain Lion Installer”. Up to you though. Then simply press the “Erase…” button on the bottom right when done. The USB Flash drive will then start to format; in most cases it takes less than a minute.

---

If you don’t already have a USB flash drive, or want a USB flash drive that is already compatible with Mac OS X then you can purchase one from the MacMall. It’s a good place to buy Mac friendly stuff. Here’s an affiliate link to a 16GB USB drive that comes already properly formatted for the purpose of installing Mac OS X:

Step 3 of 3 – Restore Disk Image

Restore Disk Image

Once your USB flash drive has finished formatting, it’s time to “restore” the drive image. In Disk Utility select the partition that was just formatted and click the restore tab. Make sure to select the partition that you’ve created and not the drive itself. To elaborate, as you can see in the screenshot, I’ve selected the partition I named “Mac OS X Install ESD”, not the drive itself. If you select the drive instead of the partition, then it won’t restore the disk image onto your USB flash drive.

There are two input boxes. One labelled “Source:” the other “Destination:”.

For the “Source:” box either drag the “InstallESD.dmg” file in, or click the “Image…” button, navigate to your desktop and select “InstallESD.dmg”. The destination will be the partition you’ve created. Simply drag the partition that’s on the USB drive that you formatted into the “Destination:” box from the panel on the left of Disk Utility.  Next simply press the “Restore” button on the bottom right.

This could take a while to complete, let it do its thing. Once the process is done, your USB drive is ready to go.

If you want to use the USB to format a new computer or re-format your current computer, there are 2 ways of getting it installed. One is to go to System Preferences -> Startup Disk -> and select the USB drive. This will load up the Mac OS X Mountain Lion installer as soon as you restart your computer. The other method is to simply hold down the Options key on the keyboard when your Mac is just turning on after being shutdown/restarted.

Once it’s done booting into the installer it’s a simple process of going through the provided setup steps.

Computer Requirements

You need a computer with Windows to run Mac OS X on Windows (of course). The "System Type" of your copy of Windows needs to be 64-bit, because OS X Mountain Lion is a 64-bit operating system. If you have a 32-bit copy of Windows, you can only install Mac OS X Snow Leopard on Virtualbox. You will need at least 4 GB of RAM and a dual-core (two core) processor or better. Personally, the computer I was using for this had a 4-core processor and 12 GB RAM, which is way more than enough. You also need about 10 GB of unused hard drive space.

Right click on "My Computer" on your desktop and click "Properties" to check the stats on your computer. If it doesn't directly tell you how many cores your processor has, look up your processor model on Wikipedia or Google. You also want to find out whether your processor is made by "Intel" or "AMD". Computers with AMD processors will not work with Mountain Lion. 

General Requirements

• Virtualbox : This virtualization suite is free, and though it doesn't offer official support for Mac OS X, it works well enough.


• Mountain Lion bootable DVD : Unfortunately, the standard method for installing OS X Mountain Lion on PCs(which uses a paid copy of the Mountain Lion installer) doesn't work with Virtualbox. Instead, you'll have to rely on pirated "bootable DVD" copies of Mountain Lion, also known as "distros". I won't go into details, but you can download these copies from about any bittorrent website by using a bittorrent client (it's about 4.5 GB in size). In the past, we've used the iAtkos distro for this, but iAtkos hasn't updated for Mountain Lion yet, so I used the "OS X 10.8 Mountain Lion bootable DVD for Intel PCs", by Olarila.


• Hackboot 1 / Hackboot 2: Even though it's called a "bootable DVD", the Olarila version of OS X Mountain Lion still can't boot in Virtualbox by itself. To help Mountain Lion start, you'll need to use Olarila's Hackboot CD. There are three different versions of Hackboot; we'll need to use two of them in this guide. "Hackboot 1" is for starting the Mountain Lion installer, while "Hackboot" 2 is for starting Mountain Lion itself.


• Multibeast 4.6.1 : You will need to use Multibeast 4.6.1, our favorite Hackintosh post-installation tool, to set up the Mountain Lion virtual machine after the initial installation. While Multibeast 4.6.1 is an old version designed for Mac OS X Lion instead of Mountain Lion, in our case, it actually works better than newer versions of Multibeast. Registration is required on the tonymacx86 website to download this.

Step 1: Prep

Download Virtualbox, install it, and open it up. Also, if you want to be able to view USB devices from your OS X Mountain Lion virtual machine, download the Virtualbox Extension Pack and run it before going to Step 2.

Step 2: Create a new virtual machine.

Virtualbox lets you run Mac OSX within Windows by creating a virtual machine, which is a program that simulates a normal computer.  To create a virtual machine, open up Virtualbox and click "New" on the upper left. Give your new virtual machine a name, and choose "Mac OS X" for the OS Type.

If your version of Virtualbox asks you to choose between 64-bit and 32-bit, be sure to choose 64-bit. Choosing 32-bit will result in a critical "Guru Meditation" error later on.

I recommend assigning 4 GB of RAM to the virtual machine, but you can assign as little as 2 GB of RAM. Every time you turn on Mac OS X, that RAM that you assign here will be used to run the virtual machine. The RAM will be given back to your normal computer after you turn Virtualbox off.

You'll need to create a new hard disk for the virtual machine. Virtualbox will ask you what type of disk you want to create: VDI, VDMK, or VHD. VDI is the original format for Virtualbox, while VDMK is the format used by VMWare. If you're considering getting a copy of VMWare, you might want to choose VDMK. Otherwise, just choose VDI. I recommend creating a dynamically expanding disk; the only other option, fixed-size storage, will eat up your hard drive.

Step 3: Give your new virtual machine an operating system.

Your virtual machine will now be created. But don't stop now--you still need to change a few settings before your machine will actually work. Your new virtual machine will show up on the left column of the Virtualbox start page.  Select your Mac OS X virtual machine (single-click) from the main page of Virtualbox, and open up the virtual machine settings. Once the settings open up, go to "System" and uncheck the "Enable EFI" box. This is by far the most important single setting that you will need to change.

EFI, which stands for Extended Firmware Interface, is a feature that helps operating systems start up. Unfortunately, Mac OSX requires 'speshul' EFI, so the EFI that Virtualbox uses doesn't work.

Once you're done with that, go to the settings for "Storage". In the storage tree box, you'll see a CD icon labeled "Empty". Click on it and click "Choose a virtual CD/DVD disk file". In the window that pops up, choose the .iso file for Hackboot 1 (download below).

DOWNLOAD: Hackboot 1

This way, when your virtual machine starts for the first time, it will boot into Hackboot.

Step 4: Install OS X Mountain Lion

Start up your virtual machine. You will come up to the Hackboot boot screen, with a CD icon labeled "HackBoot" in the middle. Don't do anything yet.

Your mouse cursor will probably be trapped inside the virtual machine. Press the right "Ctrl" key on your keyboard to allow your mouse to escape. Then, at the bottom right of the virtual machine screen, right-click on the little CD icon, and click "Choose a virtual CD/DVD disk file". A Windows Explorer window will pop up; from there, select the OS X 10.8 Mountain Lion bootable DVD.

Click back into the Hackboot screen, and press the "F5" key on your keyboard. This will refresh Hackboot. The CD icon in the middle of the Hackboot screen will now say "OS X Install DVD". Press the enter key on your keyboard. You will then enter the Mac OS X installer page.

Continue, and you will eventually come up to a page that asks you for a "destination" for your Mac install. Oh no, the page is blank! We'll have to fix that. To do this, start up Disk Utility (located under the Utilities menu).

Mac OSX can only be installed on a completely clean disk, so you need to use Disk Utility to wipe your Virtualbox hard disk. Click on the Virtualbox hard disk in Disk Utility and erase it. Don't worry, there's nothing important on it.

On the installation page for Mac OSX, the Virtualbox hard disk should now be showing up. Select it and continue.

Once that's done with, Mac OSX will install itself. This will take at least 20 minutes.

When the installation finishes, Mac OS X will crash into a black screen with white text. This is normal; Mac OS X has installed successfully. Now proceed to the next step.

Step 5: Boot it up

Again, press the right Ctrl key to allow your mouse to escape from the virtual machine screen. Then, click on the CD icon in the bottom right of the virtual machine. This time, choose the .iso file for Hackboot 2 (download below).

DOWNLOAD: Hackboot 2

Restart your virtual machine. You'll see the Hackboot screen once more, except there will be an icon for your virtual machine's hard drive in the middle.

Select it (use the arrow keys on your computer) and press "Enter". Mountain Lion will boot, and you should eventually be led to the Mac OS X setup screen. Fill it out, and you'll finally be led to the Mac OS X desktop.

This concludes the first part of the guide. However, you're not done yet! You still have to make your virtual machine bootable without the help of Hackboot.

Step 6: Fix it up
By default, your ethernet (internet) should work in the virtual machine. However, the virtual machine will not have sound, or be able to boot from the hard drive without help. To fix this, open Safari, and download Multibeast 4.6.1. While Multibeast 4.6.1 is an old version designed for Mac OS X Lion instead of Mountain Lion, in our case, it actually works better than newer versions of Multibeast. Registration is required on the tonymacx86 website to download this.

DOWNLOAD: Multibeast 4.6.1

Before starting Multibeast, you have to go the "Security" section of System Preferences in Mac OS X, go to the "General" section, and check "Anywhere" in the "Allow applications" section. Once that's done, run Multibeast and install the following options (contrary to popular belief, you do not need an actual DSDT file to use UserDSDT).

Next, you'll have to delete a certain kext file in your hard drive that causes boot errors. You can do this from Finder, the file browser built into Mac OS X. However, Finder hides your hard drives in Mountain Lion by default. To unhide them, open Finder, and click on File -> Preferences in the menu bar at the top of Mac OS X. Under the "Sidebar" settings, check "Hard disks", so that Finder will display your virtual machine's hard disks in the sidebar.

Then, go to your main hard drive, and go to /System/Library/Extensions. Inside the Extensions folder, delete the fileAppleGraphicsControl.kext.

This completes the post-installation process for your virtual machine. Eject the Hackboot CD; you can do this by right-clicking the CD icon at the bottom right of your virtual machine, and unchecking Hackboot. Then, restart your virtual machine. Mac OS X will now be able to boot normally and play audio. Congratulations!

Step 7: Make the screen bigger
Though this step is optional, I still recommend you do it anyways. Anyways, when you first use your Mac OS X, you'll probably notice one thing: your screen resolution is 1024x768. Since Virtualbox doesn't "technically" support Mac OS X, there's no official way to change this. But here's how you can change it anyways:

Open up Finder and go to the folder "Extra" in the main hard drive, and open the file org.Chameleon.boot.plist. Between <dict> and </dict> in the file, insert the following line.

<key>Graphics Mode</key>

<string>1920x1080x32</string>

You can change "1920x1080x32" to whatever resolution best fits your monitor. For instance, if you want to use the 1600x900 resolution, type in "1600x900x32". Once you've saved it, turn off the virtual machine.

Next, open the Command Prompt in Windows (make sure you are logged into an Administrator account on Windows). You can do this by opening the Start Menu, and typing "command prompt" into the Start Menu search bar. Then, type the following command into the Command Prompt.

cd "C:\Program Files\Oracle\Virtualbox"

This command will change the focus of the Command Prompt to the program folder for Virtualbox (if you installed Virtualbox somewhere different, then change the command to wherever you installed it). Next, type in this command:

vboxmanage setextradata "Name of virtual machine" "CustomVideoMode1" "1920x1080x32"

This command activates "vboxmanage", a command-line program included with Virtualbox that allows you to edit the properties of your virtual machine, including its built-in resolutions. Replace "Name of virtual machine" with the name of your virtual machine-- you can find the name of your virtual machine in the left pane of the Virtualbox main window (in the screenshot below, my virtual machine is named "Mountain Mac 2"). Replace "1920x1080x32" with whatever resolution you're using.

Press the enter key to submit the command. Once that's done, start your virtual machine again. It will now boot in full resolution. Congrats!

Recap
I'll just repeat what I said in my other two Virtualbox guides. Installing Mac OS X on a virtual machine is excellent practice for the real thing: installing Mac OS X on your actual computer. Don't get too comfortable, though. Compared to most computers, Virtualbox virtual machines are very "vanilla", meaning that they're very compatible with Mac OS X in the first place. You can't count on being that lucky with a real PC.
