Visual guide to installing Windows 10 IoT Core on your Raspberry Pi 2

In a blink of an eye, we're already 8 months into testing windows 10. The unfinished pre-release software from Microsoft has come a long way and lots of things have changed since it was initially released last October. During the day 1 keynote at Build 2015, Microsoft laid out the future of Windows 10 development and besides focusing mainly on the Universal Windows Platform, they briefly mention Windows IoT.

Internet of things is a pretty hot concept these days and just everyone is hitching onto it, even Microsoft. Quoting what Terry Myerson said "with Windows 10, we are targeting the largest device span ever". From the likes of HoloLens all the way to the smallest of devices (IoT), Microsoft is genuinely interested in bringing Windows 10 these devices.

Back in February with the release of the Raspberry Pi 2, the foundation promised in their blog post that they are closely working with Microsoft to bring Windows 10 to the tiny $35 PC. At that time, the media was going crazy and most of us thought the Raspberry Pi 2 was going to be the most affordable Windows 10 system out there.

Well, as it turns out Windows 10 for the Raspberry Pi 2 is just a platform for creators to create some pretty cool projects like the holographic robot Microsoft demoed on stage during the keynote. Called Windows IoT Core, this version of Windows 10 for small compute boards like the Raspberry Pi 2, Intel Galileo and Arduino doesn't feature a graphical UI yet.

So, here we go again. Just a few weeks back i showed you how to setup the Raspberry Pi 2 with raspbian and today, i'll give you some insights into loading Windows 10 IoT Core onto your Raspberry Pi 2. Just remember, the current Windows 10 IoT Core is a little rough and some things like Wi-Fi still does not work. Also, if you're not into modding and creating, i would refrain you from installing Windows 10 IoT Core onto your Raspberry Pi 2.

My installation guide here is based off the official installation steps and if you are interested in getting Windows 10 IoT Core onto Arduino or Intel Galileo boards, click here

(!) What will you need:

  • Raspberry Pi 2
  • microUSB for power
  • HDMI and ethernet (optional)
  • 8GB (or more) microSD card
  • Internet connection to download the package
  • PC running Windows 10 (Build 10069 or above)
  • Upwards of 30 minutes of time 

Step 1: Register with the Microsoft Connect program 

 Unlike installing the Technical Preview for Windows 10, with Windows 10 IoT Core, you will need to register as user on Microsoft's Connect program to be able to download the installation package.

Step 2: Accepting the Terms of Service


After you are done entering your details for the Microsoft Connect program, you will then be redirected to a page which requires you to accept some terms and conditions for the Windows 10 IoT Core program. Just click on each of the surveys and 'try' reading through the terms and hit the accept terms checkmark on the bottom of the page. 

Step 3: Downloading Windows 10 IoT Core for the Raspberry Pi 2

The next thing you want to do is to download the image file from the Microsoft Connect site, to simplify your life, the direct link for the Raspberry Pi 2's Windows 10 IoT Core file is below. The ZIP file is about 500mb and depending on your internet connection, this will take a while.


Step 4: Extract flash.ffu from the ZIP file

Once you are done with the download, navigate your way to the downloads folder or wherever it is and click onto the ZIP file you just downloaded. You do not need to install a separate un-zipper software because Windows 10 already has one build in.

In the folder, find the file called flash.ffu (it's the biggest file in there) and copy it to a place outside the ZIP file. If you're keen on exactly following my tutorial, i've simply just copied the flash.ffu file to the downloads folder.

Step 5: Launch Command Prompt 

Then the next step is to launch Command Prompt with administrator privileges. To do that, search for Command Prompt with Cortana and right click on the program and click 'Run as administrator'.

Step 6: Insert the microSD card into your PC

Once Command Prompt is launched, inset your 8GB or more microSD card into the computer and you don't need to reformat it as the process later on will do it for you. In the command prompt window, type in the following codes
diskpart
list disk
exit
If you plugged in your microSD card into the system, you should see it listed as a offline disk when you type in list disk. Note the disk number of the microSD card as it might be different on your system. For my 8GB microSD card, it is listed as Disk 1. (screenshot in the next step).

Step 7: Identify the location of your flash.ffu file

Remember the flash.ffu file that you extracted from the download package earlier, well now you need to fin the directory of that folder. What you need to do is to navigate to where you copied that file to and right click on the flash.ffu file and click properties. Navigate the 'General' tab and you will see the location of the file there.

All you have to do now is to copy or type the file location of your flash.ffu file into the command prompt window you opened earlier. Just type cd in front of your file location and hit enter. Mind you that your username might be different than mine so you will need to change that (my username: dickw).
cd C:\Users\dickw\downloads

Step 8: Installing the image file onto your Raspberry Pi 2

If you executed the previous step correctly, you will see the following line of text on the very bottom of the page
C:\Users\dickw\Downloads>
So, the next thing to do is the copy the following line of code onto command prompt. But you have to make a slight change to the code below, replace the 'N' on PhysicalDriveN with the drive number you noted down earlier. For example, my microSD card is reference by the computer as Disk 1, so i will replace PhysicalDriveN as PhysicalDrive1
dism.exe /Apply-Image /ImageFile:flash.ffu /ApplyDrive:\\.\PhysicalDriveN /SkipPlatformCheck


Step 9: You're done! 

Shortly after running that previous line of code, you should see the progress bar on screen and when it reaches 100% then you are done. That is it, installing Windows 10 IoT Core on your Raspberry Pi 2 is as simple as installing Raspbian. It's the just the command prompt codes might be a little confusing.

Conclusion

You can now plug in your microSD card onto your Raspberry Pi 2 and boot up the system. If everything goes well, you will first see the blue Windows logo come up and then a blue page with some text will come up. After that, the Pi 2 will reboot and land on the Windows 10 IoT Core Insider Preview page.

At this point in time, i can't do much with the IoT core because i don't have the tools needed for my project. But rest assured, i'll update on my project when i get it up and running.
