Boot Camp won’t have recognized Windows 10 ISO ERROR What you NEED to know: • Your downloaded ISO image from Microsoft Website maybe incomplete. Windows_10_1511_X64.iso has 3.7GB or more. If you downloaded the ISO file below than this, you will get this error. • Downloading ISO from MS website is such a pain, it stops at some point in time when you already downloaded 2.8GB or more but you still get the ISO, there is no way to check if the MD5sum of the ISO you downloaded is correct. Creating a bootable Windows 10 64bit USB flash drive did not work for me. I converted it to ISO file using OS X Disk Utility giving me 7.89GB file size.

An ISO image is a container that stores a replica of the content of a physical disc, which typically can be a CD, DVD, or even Blu-Ray. Software companies also use ISO images as a medium to. Then right-click the ISO file and select Burn disc image. If you want to install Windows 10 directly from the ISO file without using a DVD or flash drive, you can do so by mounting the ISO file. This will perform an upgrade of your current operating system to Windows 10. To mount the ISO file.

During the process, Boot Camp give me this error, “Your bootable drive cannot be created. There is not enough space available on the disk.” Take note that I am using Sandisk 3.0 32GB. To solved this issue, this is what I did.

Get the ISO file Windows 10 using Windows Media Creation Tool. • Download Microsoft Installation Media Creation Tool; • Select Windows 10 version 64bit; • Select “Create installation media for another PC”; • You will see a screen asking you to choose the media to use. Select “ISO file”; • Wait for your download to finish and copy to your USB. Use Boot Camp to install Windows from your ISO file • From PC, transfer the ISO file to Mac and paste to Documents or any location; • Open Boot Camp and locate the ISO file created using Windows Media Creation Tool. • Follow the instructions Step 3-6 here: STEP 3. You are done.

Had the same issue. You have to download the specific Windows 10 64-bit ISO from Microsoft. For instance, I used the Windows 10 Media Creator to make an ISO that had 32-bit and 64-bit versions on one disk and it didn't get recognized. Here's the link on Microsoft's site. MAKE SURE you have a Windows 10 key *FIRST*. I literally (as in the real definition of it) spent over six hours today on the phone arguing with Microsoft that I needed a key and had valid Win8.1 keys but they said no, you *have* to do an upgrade.

Called back a second time (waited 2 hours on hold *again* and got the same answers.) Another thing. If you don't have a purchased Windows 10 key and are instead getting a free update to it from Win7 or Win8x (I'm guessing not bc of wanting to boot to an iso, but just in case you think you can upgrade that way. You can't btw) the update will fail on the new rMB 2015 because of the new SSD. Specifically it will die when it's trying to reboot and say 'Something Happened' and that it failed. Simply go to 'Reboot and install updates' and it will complete the setup that way.

Once you do get the upgrade installed, you can use Magical Jellybean's KeyFinder to get your shiny new Windows 10 key, then if you want, do a clean install that way. It's sooooo annoying that MS won't just give you a Win10 key if you give them a Win8.1 key (they even remoted into my machine to confirm it was valid and installed, but still no!) Anyway, hope that helps and saves you the three days of hurt I've had trying to get Win10 Pro on my 2015 rMB 12'. Boot Camp absolutely supports it. You just *have* to use their Boot Camp utility to create a bootable USB stick because it installs drivers for the SSD, keyboard and trackpad needed *during the install!* If you simply create the partition, then try to boot from the Windows ISO, you'll be left a) without a keyboard and trackpad to even let you click through the installer, but even if you then connect them via USB, it will not see the SSD when choosing a partition. Actually you won't see anything in that list. You need the bootable media to have Windows recognize the SSD to install on. When you do, then you'll have a working keyboard and trackpad, and you'll see the boot camp partition.

• Unpack and run the installer Depending on which web browser you're using and your browser's configuration, your browser may automatically open the '.dmg' file which was just downloaded. Adobe flash player for mac. The installer will then download to your computer. If it doesn't automatically open, once the download has completed, open your Downloads folder and find the 'dmg' installer file. Ensure that it is actually the same file you just downloaded from Adobe.

Found that out the hard way. I'm actually making bootable ISO's from those bootable USB drives so they will have the required drivers should I again try to do a clean install from the CD. Few clarifications to the above and an update on my update! 🙂 One, using the ISO created by Microsoft's Win10 MC tool doesn't work for the Retina MacBook 12' 2015. Nor does using the direct ISO downloads that I mentioned. While you can *boot* from the ISO, as I said above, you can't actually do anything once you're booted in and starting at the first step of setup because the keyboard and trackpad don't work. Even if you plug in a keyboard and mouse over USB (through the USB to USB-C adapter) you still won't see the SSD when choosing a partition.
