The process may take a few minutes depending on the size of the image and the speed of your computer. During the process, the app will show you the progress and estimated time remaining.

Step 5: Verify the Image

Once the flashing process is complete, Balena Etcher will automatically verify the image’s integrity. This step is essential because it ensures that the image was successfully written to the SD card.
