====Changeable operating systems====
Most computers have hardware (for example, central processing units, chips, disk drives, audio, video, and networking devices) that can work with changeable operating systems.  So a Microsoft Windows computer can be booted with a different operating system, like one of the GNU/Linux variations that Sugar is built on.

When a computer is powered up, a short piece of software saved in the computer's [[wikipedia:firmware|firmware]] gives it instructions to look for instructions to load an operating system from one or another standard devices, such as hard disk drives or CD/DVD/USB/SD storage devices.

# Insert the USB drive into a USB port on your computer. Ports directly connected to the mother board, or main circuit board, (usually made available on the back of the computer) are more likely to recognize the device at boot time.
 
# Set the option to "boot from USB" in your computer's [[wikipedia:BIOS|BIOS]], and then start up the computer. This can be done in a number of ways and will VARY from machine to machine. What you are looking for is the term "Boot Loader" or "Boot Order" or something to that effect. You may have to play around with the settings quite a bit to achieve success. The BIOS is usually not a graphical user interface. Your mouse will not work, generally, in the BIOS. Use the arrow keys. Read the help lines for each BIOS option. If you've not gone into the BIOS before, don't be afraid, you can't do too much damage there, if you pay attention.

You do this by interrupting the Helper CD boot by hitting the '''Esc''' key once the initial splash-screen appears. You should see a list of four boot options. At this point, hit the '''Tab''' key. The command line should appear. Add <code>selinix=0</code> to the end of the line and hit '''Enter''' (or Return). The boot should proceed from here as normal.
