installing UBUNTU ~ JUOL COMPUTER

Ubuntu is a computer operating system based on the Debian GNU/Linux distribution and distributed as free and open source software. It is named after the Southern African philosophy of Ubuntu ("humanity towards others"). Ubuntu is sponsored by the UK-based company Canonical Ltd., owned by South African entrepreneur Mark Shuttleworth. Canonical generates revenue by selling technical support and services related to Ubuntu, while the operating system itself is entirely free of charge.
Installing UBUNTU
Installation of Ubuntu is generally performed with the live CD or can be installed via a live USB drive. The Ubuntu OS can be run directly from the CD (sometimes with a significant performance loss), allowing a user to "test-drive" the OS for hardware compatibility and driver support. The CD also contains the Ubiquity installer, which can then guide the user through the permanent installation process. CD images of all current and past versions are available for download at the Ubuntu web site. Installing from the CD requires a minimum of 256 MiB of RAM.
Users can download a disk image (.iso) of the CD, which can then either be written to a physical medium (CD or DVD), or optionally run directly from a hard drive (via UNetbootin or GRUB). Ubuntu is also available on ARM, PowerPC, SPARC, and IA-64 platforms, although none are officially supported.
Canonical offered Ubuntu and Kubuntu Live installation CDs of the latest distribution of the operating system at no cost (though discontinued as of April 2011), including paid postage for destinations in most countries around the world (via a service called ShipIt). Various third-party programs such as remastersys and Reconstructor are available to create customised copies of the Ubuntu Live CDs.
A Microsoft Windows migration tool, called Migration Assistant (introduced in April 2007), can be used to import bookmarks, desktop background (wallpaper), and various settings from an existing MS Windows installation into a new Ubuntu installation.
Ubuntu and Kubuntu can be booted and run from a USB Flash drive (as long as the BIOS supports booting from USB), with the option of saving settings to the flashdrive. This allows a portable installation that can be run on any PC which is capable of booting from a USB drive. In newer versions of Ubuntu, the USB creator program is available to install Ubuntu on a USB drive (with or without a LiveCD disc).
Wubi, which is included as an option on the Live CD, allows Ubuntu to be installed and run from within a virtual Windows loop device (as a large image file that is managed like any other Windows program via the Windows Control Panel). This method requires no partitioning of a Windows user's hard drive. Wubi also makes use of the Migration Assistant to import users' settings. It also incurs a slight performance loss.
