I have a MacBook and I'd like to install Windows 7 via USB. I've created the partition using Boot Camp and I've got an.ISO of my Windows 7 install disk. Is it possible to install this via USB, ins. Sep 22, 2019  I don't have my superdrive in my macbook so I'm trying to install windows 7 using bootcamp and the USB stick. I made a 100GB partition on my SSD to use for windows using bootcamp. When I restart and hold the alt key, my bootable USB for windows 7 never appears. May 17, 2017 For Mac users who also need to use a PC at work, home or just with specific applications, there is a solution. Using Boot Camp Assistant, you can install Windows 7 on your Intel-based Mac computer in its own partition.

How do I use the Boot Camp 5 Support Software I downloaded from the web page? Boot Camp Mac Install Windows 7 From Usb


  1. The download file is a .zip file. Double click it to uncompress it.
  2. Double-click the Boot Camp disk image.
  3. Copy the Boot Camp and '$WinPEDriver$' folders to the root level of a USB flash drive or hard drive that is formatted with the FAT file system (see question below for steps on how to format).
  4. Install Windows, leaving the flash or hard drive attached to the USB port of your Mac.
  5. Installation of the drivers can take a few minutes. Don't interrupt the installation process. A completion dialog box will appear when everything is installed. Click Finish when the dialog appears.
  6. When your system restarts your Windows 8 installation is done.
Note: If the flash drive or hard drive was not attached when you installed Windows and was inserted after restarting into Windows 8, double-click the Boot Camp folder, then locate and double click the 'setup.exe' file to start the installation of the Boot Camp 5 Support Software.

How do I format USB media to the FAT file system?
Use Disk Utility to format a disk to use with a Windows computer. Here's how:

Important: Formatting a disk erases all the files on it. Copy any files you want to save to another disk before formatting the disk.

  1. Open Disk Utility.
  2. Select the disk you want to format for use with Windows computers.
  3. Click Erase, and choose one of the following from the Format pop-up menu:
    • If the size of the disk is 32 GB or less, choose MS-DOS (FAT).
    • If the size of the disk is over 32 GB, choose ExFAT.
  4. Type a name for the disk. The maximum length is 11 characters.
  5. Click the Erase button and then click Erase again.


Boot Camp Assistant: Install Windows on Mac worked like a charm very first time.


  1. Use the Boot Camp Assistant, not Disk Utility, to set up your drive. You will need to start with one partition (not including the 10.8 recovery partition, that's different). **** near everyone I know that's had serious issues with getting BC set up was NOT using the Boot Camp Assistant, and therefore their drive was not properly set up.
  2. Windows 7 SP1 x64 .iso file, in my case, was located on the desktop of the Retina MBP, as I'd placed it there earlier.
  3. Plug >4GB USB stick in one of the USB slots. Mine was a USB 2 stick.
  4. After making sure that I had a network connection, I left all three checkboxes checked. The Boot Camp Assistant recognized both my USB stick and the iso image on its own.
  5. After building the install iso on the stick (pretty slow process), it then downloaded the drivers from Apple and saved those to the stick. This required authentication.
  6. It then let me choose the size of the partition, partitioned the drive and rebooted to the USB stick. I've seen this fail if you have two USB sticks plugged in for some reason.
  7. Once it rebooted into the installer, I was eventually presented with a list of partition. Per the documentation, I selected the one named 'BOOTCAMP' and reformatted it NTFS. Once it finished that, the install did it's thing.

Really, it was that simple, and pretty much the same process for every other machine I have ever needed to run Windows on. I have heard stories of people having problems when using drives (especially SSDs) that were not factory standard.

Installing Windows on a Mac should be a piece of cake with Bootcamp, but thatrarely is the case. In fact, I would personally say that Boot Camp Assistantis one of the worst apps that comes with OS X and unlike the rest, it doesn’twork seamlessly.

A few of its drawbacks:

  • It only supports a drive with a single partition.
  • It often throws very obscure error messages with limited detail.
  • It re-downloads 1.6 GB Windows drivers every single time it runs. These areplaced under /Library/Application Support/BootCamp/WindowsSupport.dmg anddeleted and re-downloaded each time Boot Camp Assistant starts processing.

This post did take a lot of work to complie and I did bone my hard drive afew times while trying certain ideas, so please throw out a thanks if ithelped you out :)

Disclaimer: This guide below contains procedures which can potentiallydestroy your partitions and data. I accept no responsibility for such loss soplease proceed at your own risk.

Update (2016-07-20): I have updated this post with further improvementsrelating to downloading of Boot Camp drivers and ensuring that a Hybrid MBR isnot used (which would cause issues when installing Windows).

  • An 8 GB or larger USB stick
  • A copy of the Windows 10 ISO
  • A valid Windows 10 license
  • A downloaded copy of unetbootin
  1. Start Boot Camp Assistant
  2. Select Action / Download Windows Support Software
  3. Choose your Downloads directory, enter your password and then clickSave

This will be the only step that we will use Boot Camp Assistant for.

Formatting Your USB Stick

Attach your USB stick and start Disk Utility, select your USB drive in theleft panel under External, click Erase and set the options as follows(exactly) and click Erase:

Name: FAT32
Format: MS-DOS (FAT)
Scheme: Master Boot Record

Turning Your USB Stick into a Windows Installer

Open unetbootin, enter your password, set the options as follows andclick OK:

Diskimage: checked, set to ISO and browse to your Windows 10 ISO
Type: USB Drive
Drive: Your USB drive (you should only see one entry here)

If you see more than one drive listed, you may confirm which is your USB driveby opening the Terminal and typing:

You’ll see your USB drive in the output and it should look something like this:

Once you have kicked off unetbootin, grab a snack while the Windows ISO iscopied to the USB stick. This process takes around 15 minutes to complete.

Finishing Up

When this has completed, you may right click on the USB stick in Finder,select Rename “FAT32” and rename it as you like (I’ll call mine“WINDOWS 10”).

Finally, copy the WindowsSupport in your Downloads directory tothe Windows 10 USB stick so it’s easy to get to after our installation.

In Disk Utility, select your internal hard drive on the left panel, andclick on Partition.

Click the + button and create a new partition of your desired size for yourWindows installation and name it as you wish (I’ll call mine “BOOTCAMP”). Ensure that the Format is set to MS-DOS (FAT) and click on Apply.

Huge thanks to Rod’s post from the superuser post titledWindows detects GPT disk as MBR in EFI boot.

New cooking games 2016 download. Once you add a FAT32 partition with either Boot Camp Assistant or Disk Utility,your disk is converted into a hybrid GPT / MBR disk which is actually notsupported by newer versions of Windows. In this step, we revert thisadditional change made by Disk Utility by switching back to a pure GPTpartition table.

  1. Dowload the latest version ofGPT fdiskby browsing to the version, then gdisk-binaries and clicking the filewith the *.pkg extension (e.g. gdisk-1.0.1.pkg).
  2. Install GPT fdisk by running the installer you downloaded

  3. Open a Terminal and check the state of your MBR

    If your MBR partition is set to hybrid, please continue with step 4,otherwise if it is set to protective, you may skip the rest of thissection. Simply type q and hit return to exit GPT fdisk.

  4. Type p to view the existing partition table and verify you’re workingon the correct disk

  5. Type x to enter the expert menu

  6. Type n to create a fresh protective MBR

  7. Type w to save your changes and confirm the change when asked Dev c++ ultima version pagina oficial.

  8. Type q to exit GPT fdisk

  9. Run GPT fdisk to show your disk layout:

    Your partition table should look something like this:

Disconnecting All Devices From USB Ports

This step is critical as I have had rather serious problems during Windowsinstallation when certain external drives are connected.

Unplug everything from your Mac except your keyboard (if wired) and yourbootable Windows USB stick (which we prepared earlier).

If your Mac contains multiple physical drives, you will need to disconnectall disks except the one which you intend to install Windows on or you mayencounter the following error:

Windows could not prepare the computer to boot into the next phase of installation. To install Windows, restart the installation.

Booting From the USB Stick

Boot From Usb Windows 7

Ensure that the USB stick containing the Windows installer is inserted andthen restart your Mac while holding down the option (alt) key.

You should now be presented with a list of bootable drives. Select the USBdrive (usually titled “EFI Boot”) to begin installing Windows.

Correcting Your Windows Hard Disk Partition

When you are asked Where do you want to install Windows?, select theWindows partition created earlier (which I called “BOOTCAMP”) and clickDelete.

Next, select the chunk of Unallocated Space and click on New to createa proper Windows NTFS partition.

Note: OS X only supports creation of FAT filesystems, so this is why we needto re-create the partition ourselves during install.

Completing the Installation

Allow the installer to complete and boot into Windows.

Installing Boot Camp Support Software

Once Windows is up and running, install the Boot Camp Support software runningWindowsSupport/BootCamp/Setup.exe on your USB stick.

Note: The installer takes a little while to show up, so please be patient.

You may encounter a known issue whereby the Boot Camp Support Softwareinstaller locks up while installing Realtek audio.

If this occurs, you will need to open Task Manager and kill theRealtekSetup.exe process.

After the installer has completed, answer No when prompted to rebootand install the Realtek drivers manually by running%USERPROFILE%AppDataLocalTempRarSFX0BootCampDriversRealTekRealtekSetup.exe.If you can’t find this file, check any other directories starting withRARSFX under %USERPROFILE%AppDataLocalTemp.

Once complete, reboot Windows.

  • The flipflop-windows-sheel binary (see README for a download link)

Mapping Your Mac Keyboard

Install and run SharpKeys and then configure the following mappings tocorrect your Mac keyboard so that it behaves like a regular Windows keyboard:

Function: F13 -> Special: PrtSc
Special: Left Alt => Special: Left Windows
Special: Left Windows => Special: Left Alt
Special: Right Alt => Special: Right Windows
Special: Right Windows => Special: Right Alt

Note: for F13, you’ll need to select Press a key and click F13 on yourkeyboard.

Switching to Natural Scrolling

If you wish to flip scrolling direction to match that on OS X, runFlipWheel.exe and then click on Flip All.

Enabling Num Lock on Boot

Paste the following into a file named Enable NumLock on Boot.reg thenimport this into the registry to enable NumLock when Windows boots up(it doesn’t by default).

Completing Configuration

That’s it, give your machine one last reboot and you’ll have a fully workingWindows 10 installation.

Note: I have found Apple’s Magic Mouse to be extremely unreliable usingthe Boot Camp drivers from Apple. As such, I recommend purchasing a Logitech(or similar) mouse for use in Windows. I have no trouble plugging thewireless receiver for my Logitech mouse into one of the USB ports of my wiredApple Keyboard and it’s so tiny that you can’t see it at all.

Removing the Windows Partitions

If you decide to remove Windows, you may find that Disk Utility doesn’t allowyou to delete the two partitions that have been created by the Windowsinstaller.

This happens due to the fact that the first small partition created is of atype called Microsoft Reserved which OS X’s Disk Utility doesn’t support.

The safest way to delete these partitions is through the Windows installer. Sosimply boot from your USB stick as we did before and when you reach theWhere do you want to install Windows? question, you may delete your“BOOTCAMP” partition and the small 16 MB partition of type MSR (Reserved)just above the BOOTCAMP partition.
