lsblk

lsblk

Find the name of the SD card. The name of the SD card, not the individual partitions (Important)

Now unmount the partitions if they are mounted

umount /dev/partitionName

Now make sure you know where your image is you'd like to write to your SD card

dd bs=4M if=/path/to/img.img of=/dev/sdCardName

You should be able to boot the image now
