Flashed wrong image to micro sd - Need different image flashed instead

If I flashed the wrong image to a microsd card, what steps should I take to clear the micro sd card, and flash a new image to the same micro sd card?

Thank you ahead of time.

Hey there, good news is that you should just be able to use etcher again to flash a new image to the SD card - it will automatically clear the old image and flash the new one for you.

Thank you. This helped.
