Changes

If you already have Windows installed on your PC you can install Ubuntu Linux onto the same disk drive and boot from either operating system (a configuration know as ''dual booting''). During the installation process Ubuntu will resize the Windows partition on your hard disk to make room for the Ubuntu installation (you will be asked how much of your disk drive you wish to use for Linux) and set up a special boot manager that will allow you to choose whether to boot Linux or Windows each time you power up your system. All of this is non-destructive, in that your Windows partition and all the applications and data therein will be kept intact. All that will happen is that the Windows part of the disk will be smaller than it was originally.
