 Some distributions have a Live CD "installer", where the computer boots the operating system from the disk, and then proceeds to install it onto the computer's hard disk, providing a seamless transition from the OS running from the CD to the OS running from the hard disk.Both servers and personal computers that come with Linux already installed are available from vendors including Hewlett-Packard, Dell and System76.On embedded devices, Linux is typically held in the device's firmware and may or may not be consumer-accessible.
