Beginning the Ubuntu Linux Installation
When configuring a dual boot environment it is best to select the "Guided" option from the above dialog. At this point it is necessary to decide how much of your Windows partition you wish to donate to the Ubuntu Linux installation. Move the slider until the Ubuntu partition allocation is a size you are comfortable with (the guided option will not let you create an Ubuntu partition smaller than 3Gb - this ensures you have enough space for the operating system togetehr with approximately 1Gb remaining for your data files).
When you have selected the size of the Ubuntu partition click the ''Forward'' button to proceed with the installation. When the warning dialog appears read it carefully and click continue if you are sure you wish to proceed.
