Now that you have everything ready, it is time to turn on your Raspberry Pi. The first thing that you need to do is make sure that your monitor is set to the correct input. This is important if you want to use HDMI, because if your Raspberry Pi doesn't detect an HDMI monitor during the boot process, it will automatically use the default AV out.
When you power on your Raspberry Pi, you will see the Raspberry Pi boot screen.
The Raspberry Pi bootloader
If you see this, it means that all the bootloader files on your SD card have been found and the appropriate monitor has successfully been detected. If you don't see this, then make sure that all the cables are plugged in, your monitor or TV is on the correct input, and you have imaged the SD card correctly.
