The $25 micro computer has acquired a cult status. This is why when I wrote that Raspberry Pi sucks, I faced harsh reactions from the Raspberry Pi fans. If you have just bought a Raspberry Pi, then you are lucky to get the free RAM upgrade on it. Now when you have your Raspberry Pi in hands, lets see how to install Raspbian OS on a SD Card in Ubuntu. on it in easy way using graphical interface. The experts can use the terminal method to install it, but assuming you are a beginner it would be better to use GUI. Before going any further, just make sure that you have all the things needed to make your Raspberry Pi work.
Step 1: Download the ISO file of Raspbian OS:
You can get the image file from this Raspberry Pi site. Go to the Raspbian “wheezy” section to download it. It is downloaded in .zip format. Right click on it to extract it. It will give you an .iso image file. To use this .iso image, we need an application that can read .iso files. For this purpose, we will use ImageViewer.
Step 2: Install ImageWriter:
You can install it from Ubuntu Software Center. Open Software Center and search for ImageWriter.
Step 3: Install the OS on a SD Card:
As you know, Raspberry Pi only boots from SD card (and not USB storage). You need an SD card of at least 4 GB in size. Make sure to format SD card before installing the OS on it. Now open ImageViewer. And browse to the location of the ISO image. If you are lost, try following this path: File System->Home->User->Downloads
Important: Make sure there are no spaces anywhere in the path to the ISO image. Which means don’t save it to some directory that has “blank space” in its name.
Click on the Write to device. It will take couple of minutes to install it. Enjoy :)
