Kanotix can be installed to the hard disk using the Acritox Installer, which, depending on optical drive, hard disk and processor speed, can take around 10 - 20 minutes.
The Acritoxinstaller comes with a user-friendly interface and many advanced features like:
LVM support, dmraid support, automatic partitioning (including ntfsresize-support), installation to USB-HDDs and update-installation of existing installations.
