Download the most recent Insider Preview image for the MinnowBoard Max.
Sign in with your Microsoft Account. You need to be signed up for the Windows Insider Program to download the Insider Preview. Visit the download page for more details.
Click the desired image under the Windows 10 IoT Core Insider Preview. Once you have signed in, select the build version (a higher number indicates a newer build) and your device, click Download Now.
The Windows 10 Core IoT image for MinnowBoard Max will be used here.
Double click the downloaded ISO file. This will automatically mount the ISO as a new virtual CD-drive (Look for a new CD-ROM drive).
The mounted virtual drive contains a .msi installer file . Double click the file to start the installation and follow the installation steps.
The installer creates a new directory: C:\Program Files (x86)\Microsoft IoT\FFU\MinnowBoardMax\ which contains the image file flash.ffu.
Copy the flash.ffu to the root of the WinPE USB drive you created in Step 2 above. This USB drive will be used in the next step to install Windows IoT.
Eject the USB drive when done.
