Hey,

Welcome to SpectoLogic. I am Andreas, blogging for SpectoLogic, an organization that is currently, hmm under construction :-). Let’s dive into the topic.

Since my Raspberry PI II had been laying around for a while and Microsoft released now a first preview of „Windows 10 IoT Core Insider Preview“ I decided to get my hands dirty. I first stumbled across an article from Mario Fraiss on how to set up your Raspberry Pi with Windows 10 IoT in a Hyper-V or physical environment.

Unfortunately I am running Windows 10 Preview under Hyper-V and the solution he provides for the Hyper-V variant involves messing up with drivers of your SD-Device. Something I did not want to do on my precious device.

So I came up with the plan to write the image to a virtual drive and then move this over to the SD-card with the Win32 Disk Imager.

I created a second disk for my Windows 10 machine in my Hyper-V environment (Fixed Disk 8 GB in size, also a VHDX-File). Then in Windows 10 I ran the dism-statement (see his blog) and applied the image to this virtual disk that looks physical to Windows 10 *gg*. Everything worked fine.

The challenge began when I tried to run Win32 Disk Imager. Because I was not able to choose the fixed disk. This is due the implementation of Win32 Disk Imager which only allows the selection of removable devices (probably to protect unexperienced users from overwriting their operating system).

So I downloaded the source code and tools which I installed promptly on Windows 10. The culprit lies in disk.cpp in the method

• bool checkDriveType(char *name, ULONG *pid)

Simply replace following code:

if (GetDisksProperty(hDevice, pDevDesc, &deviceInfo) &&

    (

        ((driveType == DRIVE_REMOVABLE) && (pDevDesc->BusType != BusTypeSata)) || 

        ((driveType == DRIVE_FIXED) && 

         ((pDevDesc->BusType == BusTypeUsb) || (pDevDesc->BusType == 0xC) || (pDevDesc->BusType == 0xD)) 

        ) 

    ) 

   )

with this one

if(GetDisksProperty(hDevice, pDevDesc, &deviceInfo))

Then I recompiled the thing which was an adventure on it’s own as usually with QT. With my new version of Win32DiskImager No Protect (Use at YOUR OWN RISK) I  created an IMG-File (just select the first of the volumes, the tool internally uses the physical disk, so all the other partitions follow :-)).

Then I copied the 8GB IMG-File to my primary machine where I have my SD-Card attached and used the regular Win32 Disk Imager to apply the image to my SD-Card.

And you are ready to use it with your raspberry pi II. The reason why you see only one partition in Windows on your SD is that there are no drive letters assigned to the partitions.
