Jun 26, 2016 Running a Surface 4 Pro with Windows 10. All info I can find refers specifically to a Windows Install.iso. My problem is ANY.iso Windows says it can't mount because the disc image file is corrupted. These are.iso files that are functioning ok on my Mac, and I made one in Windows from a DVD. Still corrupt.
64GB or more free storage space on your Mac startup disk:
- Your Mac can have as little as 64GB of free storage space, but at least 128GB of free storage space provides the best experience. Automatic Windows updates require that much space or more.
- If you have an iMac Pro or Mac Pro with 128GB of memory (RAM) or more, your startup disk needs at least as much free storage space as your Mac has memory.2
An external USB flash drive with a storage capacity of 16GB or more, unless you're using a Mac that doesn't need a flash drive to install Windows.
A 64-bit version of Windows 10 Home or Windows 10 Pro on a disk image (ISO) or other installation media. If installing Windows on your Mac for the first time, this must be a full version of Windows, not an upgrade.
- If your copy of Windows came on a USB flash drive, or you have a Windows product key and no installation disc, download a Windows 10 disk image from Microsoft.
- If your copy of Windows came on a DVD, you might need to create a disk image of that DVD.
How to install Windows 10 on Mac
To install Windows, use Boot Camp Assistant, which is included with your Mac.
1. Use Boot Camp Assistant to create a Windows partition
Open Boot Camp Assistant, which is in the Utilities folder of your Applications folder. Then follow the onscreen instructions.
- If you're asked to insert a USB drive, plug your USB flash drive into your Mac. Boot Camp Assistant will use it to create a bootable USB drive for Windows installation.
- When Boot Camp Assistant asks you to set the size of the Windows partition, remember the minimum storage-space requirements in the previous section. Set a partition size that meets your needs, because you can't change its size later.
2. Format the Windows (BOOTCAMP) partition
When Boot Camp Assistant finishes, your Mac restarts to the Windows installer. If the installer asks where to install Windows, select the BOOTCAMP partition and click Format. In most cases, the installer selects and formats the BOOTCAMP partition automatically.
3. Install Windows
Unplug any external devices that aren't necessary during installation. Then click Next and follow the onscreen instructions to begin installing Windows.
4. Use the Boot Camp installer in Windows
After Windows installation completes, your Mac starts up in Windows and opens a ”Welcome to the Boot Camp installer” window. Follow the onscreen instructions to install Boot Camp and Windows support software (drivers). You will be asked to restart when done.
- If the Boot Camp installer never opens, open the Boot Camp installer manually and use it to complete Boot Camp installation.
- If you have an external display connected to a Thunderbolt 3 port on your Mac, the display will be blank (black, grey or blue) for up to 2 minutes during installation.
How to switch between Windows and macOS
Restart, then press and hold the Option (or Alt) ⌥ key during startup to switch between Windows and macOS.

1. If you're using an iMac (Retina 5K, 27-inch, Late 2014) or iMac (27-inch, Late 2013) or iMac (27-inch, Late 2012) with a 3TB hard drive and macOS Mojave or later, learn about an alert you might see during installation.
2. For example, if your Mac has 128GB of memory, its startup disk must have at least 128GB of storage space available for Windows. To see how much memory your Mac has, choose Apple menu > About This Mac. To see how much storage space is available, click the Storage tab in the same window.
3. These Mac models were offered with 128GB hard drives as an option. Apple recommends 256GB or larger hard drives so that you can create a Boot Camp partition of at least 128GB.
2015 is going to be a big year for Microsoft with the forthcoming release of Windows 10 — you can read all about Microsoft's big January event right on our sister site Windows Central. Windows 10 is available as a technical preview, and if you're interested in trying it out on your Mac, you can do so safely without jeopardizing any of your Mac stuff, using virtualization software. What's more, you don't need to spend a dime doing it. Because both the Windows 10 preview and the virtualization software is free.
Step 0: Virtualization or Boot Camp?
Before you get Windows on your Mac, you have to decide how you want to run it: virtually within OS X, or on a separate hard drive partition using Boot Camp. Using software provided by Apple, you can turn your Mac into a dual-booting computer capable of running Windows or OS X natively. When your Mac is running Windows using Boot Camp, your Mac is a Windows PC. In order to do this, however, Boot Camp requires you to repartition your Mac's hard drive.
Virtualization software works differently: You're not messing with your Mac hard drive's partition map, you're just creating files and running Mac software that creates a virtual instance of a PC. If something goes really wrong — and this is preview software, remember — it's a lot easier to clean up the pieces using virtualization software than it can be if parts of your Mac's hard drive gets hosed.
Boot Camp doesn't officially support Windows 10 yet, and as such, its drivers may not play 100 percent nicely with the technical preview if you choose that route. I plan to revisit Boot Camp support for Windows 10 after Microsoft officially releases the new version, and I'll post my results. In the interim, though, I don't recommend using Boot Camp for Windows 10 Technical Preview.
Step 1: Download virtualization software
Running virtualization software seems to be the smartest option on the table at present for Microsoft's Windows 10 preview, and both Parallels Desktop or VMware Fusion are good options if you have them around.
If you don't already have virtual machine software on your Mac, you can download Oracle's VirtualBox. It's a virtualization tool just like Fusion and Parallels, but it has the virtue of being free. There are trial versions of Parallels Desktop and VMware Fusion which won't make you pay a fee for a two weeks or one month, respectively, so you're welcome to try those out if you prefer. But if you never want to pay a fee, check out VirtualBox.
My experience is that compared to VMware Fusion and Parallels Desktop, VirtualBox doesn't offer the same sort of robust performance or have quite as polished Mac integration (though there's no charge for it). You get what you pay for, et cetera.
Here are some links to virtualization software you can download for your Mac:
Step 2: Download Windows 10
After you have virtualization software, you'll need to download an ISO image of the Windows 10 technical preview. The ISO image is, for all intents and purposes, an exact copy of a physical Windows installation disc. You get this image from Microsoft itself by downloading it directly.
To get the disc image, you will need to register as part of Microsoft's Windows Insider Program. If you haven't already created a Microsoft account for OneDrive or Xbox Live or the like, you can do this during registration. You can also link the account to an existing email address to make it easier to remember and find later (much like iCloud).
Once you're set up and registered, Microsoft links you to a web page to download links; that page includes the product key you need to activate your preview version of Windows 10.
Step 3: Create a new virtual machine
- Launch VirtualBox.
- Click on the New button.
- In the Name field, type 'Windows 10' or whatever you'd like.
- Leave Type as Microsoft Windows
- Click on the Version menu and select Windows 8.1 (64 bit).
You should be able to use the default settings for the next several screens, assuming your base goal is to just poke around Windows 10 and see how it works. Create a virtual hard drive; set the file type to VDI; and make the drive dynamically allocated. This will create a virtual machine that will be listed in VirtualBox's Manager. Select it and click the Start button.
Step 4: Install Windows 10 Technical Preview
When you finish creating your virtual machine, you'll be prompted with the following: 'Please select a virtual optical disk file or a physical optical disk to start your new virtual machine from.' Click on the folder icon to bring up a file browser which you can use to locate the Windows Technical Preview ISO file you downloaded.
Download Windows 10 Disc Image For Mac
Click the Start button.

Follow the instructions given by the Windows 10 Technical Preview installer. It will ask you where you want to install Windows; the only option should be a drive with unallocated space corresponding to the virtual hard drive you've just created in VirtualBox. Select it and click Next.
The rest of the process is just a step-by-step setup, and that's literally all there is to it. After a virtual machine restart, you should soon be staring at a virtualized desktop of Windows 10, running on your Mac.
Any questions?
As I mentioned above, VirtualBox's Mac integration isn't quite as tight as its commercial virtualization alternatives; it's a bit easier with those to switch display resolutions, use accessories, and integrate your Mac's own files. But if you're on a short budget or just want to mess around with Windows 10 prior to its release, VirtualBox and the Windows technical preview can give you what you need without setting you back any cash. That counts for something.
