| − | The RPI will not boot up without an SD Card that is properly formatted to contain a suitable boot loader and operating system.
| |
| − | | |
| − | The distribution we have chosen to run in this lab and subsequent labs is called Raspbian.
| |
| − | | |
| − | We will use NOOBS operating system installer to install Raspbian
| |
| − | | |
| − | #Using a computer with an SD card reader, visit the raspberry pi official downloads page.

| − | #You will need a 4GB or larger card. You will need a 4GB or larger card. NOOBS holds the various distros and support files for the “recovery” process. Basically, the installer lives on the card
| |
| − | #Go to the SD Association’s website and download SD Formatter 4.0 for Windows<br/>([https://www.sdcard.org/downloads/formatter_4/ https://www.sdcard.org/downloads/formatter_4/])
| |
| − | #Follow the instructions to install the software.
| |
| − | #Insert your SD card into the computer or SD card reader and make a note of the drive letter allocated to it.
| |
| − | #In SD Formatter software, select the drive letter for your SD card and format it.
| |
| − | | |
| − | '''Copy and Paste the NOOBS files'''
| |
| − | | |
| − | #Once your SD card has been formatted, copy all the files in the extracted NOOBS folder and paste them onto the SD card drive.
| |
| − | #When this process has finished, safely remove the SD card and insert it into your Raspberry Pi.

| |
| − | #Find the device, assuming your system is different to mine. The easiest way is to run the following:
| |
| − | | |
| − | '''''#fdisk -l'''''
| |
| − | | |
| − | (This command lists all the mounted and unmounted devices on your computer.)
| |

| − | '''Noobs installer First boot'''
| |
| − | | |
| − | #Plug in your keyboard, mouse and monitor cables.
| |
| − | #Now plug in the USB power cable to your Pi.
| |
| − | #Your Raspberry Pi will boot, and a window will appear with a list of different operating systems that you can install. We recommend that you use Raspbian – tick the box next to Raspbian and click on <code>Install</code>.

| |
| − | | |
| − | #Raspbian will then run through its installation process. Note this can take a while.
| |
| − | #When the install process has completed, the Raspberry Pi configuration menu (raspi-config) will load. Here you are able to set the time and date for your region and enable a Raspberry Pi camera board, or even create users. You can exit this menu by using Tab on your keyboard to move to <code>Finish</code>.

| − | '''<u>Logging in with Default username and password</u>'''
| |
| − | | |
| − | The OS will boot to command line where you will need to enter the default username and password
| |
| − | | |
| − | *The default login for Raspbian OS<br/>Username: <code>pi</code> with the<br/>Password: <code>raspberry</code>
