Now perform the following steps;
- The downloaded image unzips to 16Gb so make sure you have at least this amount of free disk space).
- Download and install Win32 Disk Imager from this link: http://sourceforge.net/projects/win32diskimager/files/latest/download
- Unzip the SdCard image
- Plug the SdCard into an SdCard slot or adaptor for your PC.
- Run the unzipped Win32DiskImager.exe application (may just be shown as Win32DiskImager depending on your windows settings)
- Ensure the correct driver letter is selected for the SD card – double check this is right in Windows Explorer as Win32DiskImager will overwrite the entire drive without warning if the wrong drive is selected!
- Select the unzipped image file.
- Press Write and wait for the program to write the operating system onto the SD card. If the iwi32diskimager complains the image is too big to fit on your 16Gb SD card, just continue anyway. The last part of the image is empty anyway.
- Once the writing is done plug the SD card into the Raspberry Pi 2B or Pi 3 and power it up
