MicroSD card issue

Remember, if you boot your Raspberry and nothing is working, you may have burned your microSD card wrong. This means that your card may not contain any boot partition as it should, and it is not able to boot the first files. This problem occurs when the distribution is burned to /dev/sdd1 and not /dev/sdd, as it should be. This is a common mistake, and there will be no errors on your monitor. It will just not work!
