When you first turn on your computer, a ``bootloader'' is responsible for initiating the start of an operating system, such as Ubuntu or Windows.

1629.

\marginnote{A \define{bootloader} is the initial software that loads the operating system when the computer is powered up.}

1630.

When you installed Ubuntu, you automatically installed an advanced bootloader called \define{\acronym{GRUB}}. \acronym{GRUB} allows you to choose between the various operating systems installed on your computer, such as Ubuntu, Windows, Solaris, or \OSX. If Windows is installed after Ubuntu, the Windows installation removed \acronym{GRUB} and replaced the bootloader with it's own. As a result, you can no longer choose an operating system to use. You can restore \acronym{GRUB} and regain the ability to choose your operating system by following the steps below, using the same \acronym{DVD} you used to install Ubuntu.

First, insert your Ubuntu \acronym{DVD} into your computer and then restart the computer, making sure to instruct your computer to boot from the \acronym{DVD} drive and not the hard drive (see \chaplink{ch:installation}). Next, choose your language (\eg, English) and select \menu{Try Ubuntu}. Once Ubuntu starts, click on the top-most icon in the Launcher (the Dash icon). Then, search for \userinput{Terminal} using the search box. Then, select Terminal in the search results (or press \keystroke{Ctrl+Alt+T}). A window should open with a blinking prompt line. \paragraph{} Enter the following, and press the \keystroke{Enter} key:

\marginnote{The device (\filepath{/dev/sda1}, \filepath{/dev/sda2}, etc.) we are looking for is identified by the word ``Linux'' in the System column. Modify the instructions below if necessary, replacing \filepath{/dev/sda1} with the name of your Linux device.} This output shows that your system (Linux, on which Ubuntu is based) is installed on device \filepath{/dev/sda1}, but as indicated by the asterisk in the Boot column, your computer is booting to \filepath{/dev/sda2} (where Windows is located). We need to fix this by telling the computer to boot to the Linux device instead.

To do this, create a place to connect your existing Ubuntu installation with your temporary troubleshooting session:
