Run Win32 Disk Imager, preferably using the “Run as Administrator” option. You may need to right-click on the software’s icon and select “Run as Administrator” if you do not have administrator privileges on your account. Select the image file you wish to flash. If the file does not appear, simply change the “Disk Images” option to “All Files”. Select the file you need and then choose which drive you want to flash the image file to.
Insert your SD card or USB flash drive to the computer and the app should detect it in a few seconds. Select the device you want to flash the image file to and click the “Write” option. Click yes if the program asks to confirm overwriting the contents in the SD card or USB flash drive.
