the way that works best for you. When adding Linux to a Windows computer, you'll install a boot manager [http://en.wikipedia.org/wiki/Boot_manager], such as GRUB [http://en.wikipedia.org/wiki/Grub] or LILO [http://en.wikipedia.org/wiki/LILO_%28boot_loader%29]. In Ubuntu and Puppy, this is an option in the last step in the install process. GRUB takes over the master boot record [http://en.wikipedia.org/wiki/Master_boot_record]
