This page describes how to set up your computer in order to dual boot Ubuntu and Windows. Although this may seem obvious, it is important to back up your files to an external backup medium before attempting a dual-boot installation (or any other hard drive manipulation), in case your hard drive becomes corrupted during the process. External hard drives, USB flash drives, and multiple DVDs or CDs are all useful for this purpose. Some computer manufacturers that pre-install Windows provide a Windows recovery/re-installation CD or DVD with the computer. You may need to request a physical recovery/re-installation CD or DVD directly from your computer manufacturer. Once you have created a physical backup disc from a restore-image partition on the hard-drive, the restore-image partition can either be removed or left in place. When a Windows installation already occupies the entire hard drive, its partition needs to be shrunk, creating free space for the Ubuntu partition.
