Install Windows on the external drive using WinToUSB Step 1: Drag the WinToUSB installer and the WindowsSupport folder from your Mac’s desktop to the virtual machine Windows desktop. Before you install Windows, install all macOS updates. On your Mac, log in as an administrator, quit all open apps, then log out any other users. The process is slightly different if you use a macOS device. To get things running, restart your Mac with the USB drive inserted. As the computer powers on, hold the Option/Alt key to access Apple's Startup Manager. From this screen, select your Ubuntu USB stick. Once your computer knows to boot from the USB drive, you can begin the Ubuntu.

You can use Boot Camp Assistant to install Windows 10 on your Intel-based Mac.

You need an external USB drive to install Windows on older Mac computers. To find out whether you have a Mac that requires an external USB drive, see the “Learn more” section in the Apple Support article Install Windows 10 on your Mac with Boot Camp Assistant. If your Mac is a newer model that doesn’t require a USB drive, follow the instructions in Install Windows on your newer Mac using Boot Camp instead.

What you need

Dongle

  • The keyboard and mouse or trackpad that came with your Mac. (If they aren’t available, use a USB keyboard and mouse.)

  • A blank 16 GB or larger external USB 2 flash drive, formatted as MS-DOS (FAT).

    To format an external USB drive as MS-DOS (FAT), use Disk Utility, located in /Applications/Utilities. In Disk Utility, choose View > Show All Devices, select the USB drive in the sidebar, then click Erase in the toolbar. In the dialog, enter a name for the drive, choose MS-DOS (FAT) from the Format pop-up menu, choose Master Boot Record from the Scheme pop-up menu, then click Erase.

  • A full-installation, 64-bit version of Windows 10 on a disk image (ISO file) or other installation media.

    You can download a Windows 10 Disc Image (ISO File) from Microsoft.

  • Sufficient free storage space on your startup drive. For information about the amount of free space needed, see the Apple Support Article Install Windows 10 on your Mac with Boot Camp Assistant.

Before you begin

Before you install Windows, make sure you back up important files.

You can use Time Machine or any other method to back up your files. For information about backing up files, see Back up your files with Time Machine and Ways to back up or protect your files.

Perform the installation

Do the following steps in order.

Step 1: Check for software updates

Before you install Windows, install all macOS updates.

  1. On your Mac, log in as an administrator, quit all open apps, then log out any other users.

  2. Choose Apple menu > System Preferences, click Software Update, then install all available updates.

    If your Mac restarts after installing an update, open Software Update again to install any additional updates.

Step 2: Prepare your Mac for Windows

Boot Camp Assistant prepares your Mac by creating a new partition for Windows named BOOTCAMP and downloading the Boot Camp support software.

Important: If you’re using a Mac notebook computer, connect it to a power source before continuing.

  1. Connect an external USB drive or insert a flash drive into the USB port on your Mac; keep it connected or inserted while you install Windows and the Windows support software.

  2. On your Mac, open Boot Camp Assistant , located in /Applications/Utilities.

  3. At the introduction screen, click Continue.

    The system is checked for total available disk space. Older Time Machine snapshots and cached iCloud files are removed to make space for Boot Camp. This process may take a long time to complete (you can click the Stop button to skip this process).

  4. At the Select Tasks step, select all the tasks, then click Continue.

  5. At the Create Bootable USB Drive for Windows Installation step, choose the Windows ISO image and the USB drive, then click Continue.

    The Windows files are copied to the USB drive. This process may take a long time to complete (you can click the Stop button to interrupt this process).

  6. At the Create a Partition for Windows step, specify a partition size by dragging the divider between the macOS and Windows partitions. If you have multiple internal hard drives, you can select a different hard drive from the one running macOS and create a single partition on that drive to use solely for Windows.

  7. Click Install.

When this step is complete, the Windows installer starts.

Step 3: Install Windows

  1. In the Windows installer, follow the onscreen instructions.

  2. When you’re asked where to install Windows, select the BOOTCAMP partition (you may need to scroll through the list of partitions to see it), then click Next.

    WARNING: Do not create or delete a partition, or select any other partition. Doing so may delete the entire contents of your macOS partition.

  3. Continue following the onscreen instructions to finish installing Windows.

    After you install the Windows software, your Mac automatically restarts using Windows.

  4. Follow the onscreen instructions to set up Windows.

Step 4: Install Boot Camp on Windows

After installing Windows, Boot Camp drivers that support your Mac hardware start installing.

Note: If the support software doesn’t install automatically, you need to install it manually. For instructions, see the Apple Support article If the Boot Camp installer doesn't open after using Boot Camp Assistant.

  1. In the Boot Camp installer in Windows, follow the onscreen instructions.

    Important: Do not click the Cancel button in any of the installer dialogs.

    If a message appears that says the software you’re installing has not passed Windows Logo testing, click Continue Anyway.

    You don’t need to respond to installer dialogs that appear only briefly during installation, but if a dialog asks you to install device software, click Install.

    If nothing appears to be happening, there may be a hidden window that you must respond to. Look behind open windows.

  2. When the installation is complete, click Finish, then click Yes to restart your Mac.

  3. After your Mac restarts, follow the instructions for any other installers that appear.

UNetbootin for Mac OS X can be used to automate the process of extracting the Ubuntu ISO file to USB, and making the USB drive bootable. The resulting USB drive, however, can be booted on PCs only. If attempting to make a USB drive that can be booted from a Mac, follow the instructions below.

Install Hackintosh From Usb

Install Mac Using Usb

We would encourage Mac users to download Ubuntu Desktop Edition by burning a CD for the time being. But if you would prefer to use a USB, please follow the instructions below.

Note: this procedure requires an .img file that you will be required to create from the .iso file you download.

TIP: Drag and Drop a file from Finder to Terminal to 'paste' the full path without typing and risking type errors.

Install Mac Using Usb Flash Drive

  • Download the desired file

  • Open the Terminal (in /Applications/Utilities/ or query Terminal in Spotlight)

  • Convert the .iso file to .img using the convert option of hdiutil

  • Note: OS X tends to put the .dmg ending on the output file automatically.

  • Run to get the current list of devices

  • Insert your flash media

  • Run again and determine the device node assigned to your flash media (e.g. /dev/disk2)

  • Run

    (replace N with the disk number from the last command; in the previous example, N would be 2)

    • If you see the error 'Unmount of diskN failed: at least one volume could not be unmounted', start Disk Utility.app and unmount the volume (don't eject).

  • Execute (replace /path/to/downloaded.img with the path where the image file is located; for example, ./ubuntu.img or ./ubuntu.dmg).

  • Using /dev/rdisk instead of /dev/disk may be faster.

    • If you see the error dd: Invalid number '1m', you are using GNU dd. Use the same command but replace bs=1m with bs=1M.

    • If you see the error dd: /dev/diskN: Resource busy, make sure the disk is not in use. Start Disk Utility.app and unmount the volume (don't eject).

  • Run and remove your flash media when the command completes

  • Restart your Mac and press alt while the Mac is restarting to choose the USB-Stick

Please notice: While all of the info and above commands are executed properly on a MacBook Air 3,2 (that is the 2010 version 13' version of the Air) the end result will not produce a bootable USB device, at least not with the image for Ubuntu 10.10 64-bit. When booting of the USB device the following message or something similar will appear: 'Missing operating system' and the process is auto-magically halted.

To get the USB device (e.g. a USB stick) to show up at all in the boot menu you also may have to reboot/turn on/off the computer a couple of times and also resync the partition tables using rEFIt. After doing this the USB should then appear as a bootable device while holding in the alt or c key when you are rebooting the computer. Notice that both the computers built in bootloader and rEFIt will identify the USB device as a Windows device, but that's not a problem and expected.

A workaround to the-usb-device-is-not-booting-problem is to:

  • Install rEFIt.
  • Create a bootable start disk using Ubuntu and a USB stick.
  • Create a separate partition on the Airs HD.
  • dd the whole USB stick to that partition.
  • Resync with rEFIt. Turn power off and on.
  • Select Pingo/Windows logo: Install should start. (Here you might want to press F6 to change parameters, e.g. use nomodeset)

Alternatively, burning a CD and installing via an external CD-drive will work fine on the Macbook Air 3,2.
