Creating A Bootable Usb Drive For Windows 10 On MacFor

Installing Windows on a Mac should be a piece of cake with Bootcamp, but that rarely is the case. In fact, I would personally say that Boot Camp Assistant is one of the worst apps that comes with OS X and unlike the rest, it doesn’t work 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 are placed under /Library/Application Support/BootCamp/WindowsSupport.dmg and deleted 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 a few times while trying certain ideas, so please throw out a thanks if it helped you out:) Disclaimer: This guide below contains procedures which can potentially destroy your partitions and data.

I accept no responsibility for such loss so please proceed at your own risk. Update (2016-07-20): I have updated this post with further improvements relating to downloading of Boot Camp drivers and ensuring that a Hybrid MBR is not used (which would cause issues when installing Windows). What You Will Need • An 8 GB or larger USB stick • A copy of the • A valid Windows 10 license • A downloaded copy of Downloading Boot Camp Drivers • Start Boot Camp Assistant • Select Action / Download Windows Support Software • Choose your Downloads directory, enter your password and then click Save This will be the only step that we will use Boot Camp Assistant for. Diskutil list FAT32 You’ll see your USB drive in the output and it should look something like this: /dev/disk2 (external, physical): #: TYPE NAME SIZE IDENTIFIER 0: FDisk_partition_scheme *16.0 GB disk2 1: DOS_FAT_32 FAT32 16.0 GB disk2s1 Once you have kicked off unetbootin, grab a snack while the Windows ISO is copied 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 to the Windows 10 USB stick so it’s easy to get to after our installation. Partitioning Your Drive In Disk Utility, select your internal hard drive on the left panel, and click on Partition. Click the + button and create a new partition of your desired size for your Windows 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. Ensuring that a Hybrid MBR is not used Huge thanks to Rod’s post from the superuser post titled. 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 not supported by newer versions of Windows.

In this step, we revert this additional change made by Disk Utility by switching back to a pure GPT partition table. • Dowload the latest version of by browsing to the version, then gdisk-binaries and clicking the file with the *.pkg extension (e.g. • Install GPT fdisk by running the installer you downloaded • Open a Terminal and check the state of your MBR. Sudo gdisk /dev/disk0 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 this section.

Simply type q and hit return to exit GPT fdisk. • Type p to view the existing partition table and verify you’re working on the correct disk • Type x to enter the expert menu • Type n to create a fresh protective MBR • Type w to save your changes and confirm the change when asked • Type q to exit GPT fdisk • Run GPT fdisk to show your disk layout. GPT fdisk (gdisk ) version 1.0.1 Warning: Devices opened with shared lock will not have their partition table automatically reloaded! Partition table scan: MBR: protective BSD: not present APM: not present GPT: present Found valid GPT with protective MBR; using GPT. Installing Windows Disconnecting All Devices From USB Ports This step is critical as I have had rather serious problems during Windows installation when certain external drives are connected. Unplug everything from your Mac except your keyboard (if wired) and your bootable Windows USB stick (which we prepared earlier).

If your Mac contains multiple physical drives, you will need to disconnect all disks except the one which you intend to install Windows on or you may encounter 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 Ensure that the USB stick containing the Windows installer is inserted and then restart your Mac while holding down the option (alt) key. You should now be presented with a list of bootable drives. Select the USB drive (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 the Windows partition created earlier (which I called “BOOTCAMP”) and click Delete. Next, select the chunk of Unallocated Space and click on New to create a proper Windows NTFS partition.
