Once you’ve downloaded the installer (to date about 1.4Gb), you will need to format a micro SD card
of at least 8Gb. You can use a variety of ways to do this depending on your desktop platform. If you use Mac
OS X, you can format the drive with Disk Utility. Or you can use the SD Formatter 4.0 utility available for
Windows or Mac OS X (http://sdcard.org/downloads/formatter_4/). Simply download the application
and install it. Then insert your micro SD card in your card reader and launch the application. Once you verify
you’ve selected the correct media, enter a name for the card (I used NOOBS) and click format. Figure 6-7
shows the SDFormatter application.

you must have an sd card reader/writer connected to your computer. some systems have sd card
drives built in (lenovo laptops, apple laptops and desktops, and so on). if you do not have an sd card
reader, you can find usB sd card readers anywhere electronics or photo equipment is sold. Most
readers can accept various formats including micro sd or micro sd via a micro sd to sd adapter.Once you’ve formatted the micro SD card, you now must copy the contents of the NOOBS image to
the card. Right-click the file you downloaded and choose the option to unzip or unarchive the file. This will
create a folder containing the NOOBS image. Copy all of those files (not the outside folder) to the SD card
and eject it. You are now ready to boot into NOOBS and install your operating system. When this process has
finished, safely remove the SD card and insert it into your Raspberry Pi.
