Connecting the hardware
Setting up your hardware in order to boot and see what's going on
The final setup we need is displayed in the diagram below. For now, this tutorial is only working for the Raspberry Pi Model 1B, Model 1B+ or Model 2B.
Make sure your harddisk is getting enough power. The Raspberry Pi is not yielding a lot of amps over the USB connectors, so even two USB ports bound together will usually not power your 2.5inch portable harddisk. Use a powered USB disk or add a powered USB Hub between the Raspberry Pi and your USB disk. I've tried without, and it won't work without.
Furthermore you need a Network cable to connect your Raspberry Pi to the internet.
Do not insert your SD Card yet, as there is no boot system on it (yet). Also don't worry if there is no signal on your HDMI monitor yet. We can fix that later, but it needs a boot system to setup a video output.
Before we can start creating this working setup, there are some other requirements that must be met.
- You need another computer to create a boot SD card. It could be a Mac, Windows or Linux (Ubuntu e.g.). I'll call this computer your main computer.
- A lot of commands need to be typed in a terminal, be it on the Raspberry Pi or on your main computer (Mac or Linux). For Windows you there are usually normal Windows programs to perform the same tasks. I will mention them if needed.
- When using Windows for SSH (we'll explain all about SSH later on) you can use Putty Portable instead of the Linux/Mac terminal. The portable version is easier to use if you do not have admin rights on the Windows machine.
Now we have a working hardware setup. Next step is to setup your boot device.
