Download the Win32DiskImager utility located here: Win32DiskImager After the download has finished, double click on the file to install Win32DiskImager on your computer.

Launch Win32DiscImager

Insert the SD card into your SD card reader (on your computer. You can use the SD Card slot (if you have one) or a cheap SD adapter in a USB port.) and check which drive letter was assigned. You can easily see the drive letter (for example G:) by looking in the left column of Windows Explorer.

In Win32DiskImager, select the image file you extracted previously, and select the letter of the SD card in the device box. Be careful to select the correct drive; if you get the wrong one you can destroy your data on the computer's hard disk!

Click Write and wait for the imaging process to complete.

Exit the imager and eject the SD card.
