When you first turn on your computer, a ``bootloader'' must start Ubuntu or another operating system. \marginnote{A \define{bootloader} is the initial software that loads the operating system when you switch on the computer.} When you installed Ubuntu, you installed an advanced bootloader called \define{\acronym{GRUB}} which allows you to choose between the various operating systems on your computer, such as Ubuntu, Windows, Solaris or Mac \acronym{OS~X}. However, when you installed Windows, it replaced the \acronym{GRUB} with its own bootloader, thus removing the ability to choose which operating system you'd like to use. You can restore \acronym{GRUB} and regain the ability to choose your operating system by using the same \acronym{CD} you used to install Ubuntu.
