The Raspberry Pi is a quite cool little computer system - nevertheless unlike normal computers it does not come preloaded with an operating system (OS). This means that in order to use the Raspberry Pi computer system you should install a OS of your selection onto a SD card as well as usage that to boot the computer system.

This post will demonstrate how to set up an os, flash it to a SD card and also boot your Raspberry Pi for the very first time.

If you want to follow the article at home you must have:

A Raspberry Pi - Version B
A SD Card (min. 2 GB).
A computer system with a net connection and a SD card reader.
A USB keyboard.
A HDMI monitor.
Choosing an Operating System (OS).

A Raspberry Pi does not run conventional os such as Windows 8 or OS X. This is since the Raspberry Pi is powered by a so-called ARM cpu, this sort of computer cpu can not perform the exact same programs as your computer. Instead it needs to run among the operating systems that have actually been optimized as well as ported to the Raspbery Pi ARM hardware design.

The good news is there are quite a few various os readily available. It is necessary to keep in mind that most of them are based on the linux bit.

Soft-float Debian "wheezy".

The soft-float debian operating system is made use of mostly if you are running intensive java based applications on your Raspberry Pi (We wont be doing that for now).

Arch Linux ARM.

This operating system is not for newbies so we wont chat more concerning it just now. However you should take a closer check out this if you are already a skilled Linux customer.

Raspbian "Wheezy".

The Raspbian "Wheezy" operating system is one of the most prominent os to operate on the Raspberry Pi. It has excellent assimilation with the hardware and comes pre-loaded with a graphical user interface as well as development tools. This will certainly can be found in really handy if you are not as well experienced in a linux atmosphere.

For the purpose of this post we will certainly make use of the Raspbian operating system since it is simple to get going with. Very first step is download and install the most up to date version of the Raspbian "Wheezy" operating system picture. It is freely offered here (scroll down to "Raw Pictures").

Once you have downloaded and move the data to a proper folder right click and also choose "Extract All ..." - this will extract the image documents from the downloaded and install zip documents.

Other Devices.

Along with the operating system we are also mosting likely to require a program that can transfer the operating system to our SD card as though the Raspberry Pi can use it too from. This program is called Win32DiskImager and also is available below free of charge.

Starting Win32DiskImager.

As soon as you have downloaded and install the Win32DiskImager documents - relocate to a proper folder, right-click as well as pick "Extract All ..." adhere to the guide to remove the program.

The program does not require to be installed - you can start it currently by dual clicking the documents "Win32DiskImager". Before starting plug the vacant SD card right into your computer system.

As soon as begun you will certainly need to pick the Rasbian "Wheezy" image documents, next choose the drive letter of your SD card.

KEEP IN MIND: Its crucial that you are 100% sure that the drive letter picked is your SD card.

Currently press "Create" as well as unwind as well as relax while the program mounts the operating system onto your SD card. While waiting you can link the Raspberry Pi to a USB Key-board & Computer Mouse and also a HDMI display or TV.

First boot.

Once we have actually configured the SD Card - plug it right into the Raspberry Pi. At this moment everything yet the power supply ought to be connected into the Raspberry Pi.

First Boot Setup.

Attach power as well as you must see the boot sequence on your TELEVISION (otherwise examine if you chose correct HDMI input on TELEVISION). After first boot the Raspberry Pi boot in arrangement setting. If it does not boot into configuration setting you can type the following command to arrive:.

sudo raspi-config.
When in setup mode we want to:.

Re-size to file-system to utilize the whole SD card in my situation (4GB) (First option in arrangement menu).
Adjustment the location to match your area (This is located under "Internationalization Options").
Modification the timezone to match your location (This is found under "Internationalization Options").
We can currently reboot the raspberry and also when it boots once again it will create our new arrangement! To log in use the adhering to credentials:.

User: pi.
Password: raspberry.
Your Raspberry is now configuration, configured and also prepared for you to use for any type of function you want.
