Why try Kubuntu?

There are many good reasons to install Kubuntu! Some of them include:

  • Kubuntu makes your PC friendly.
  • Kubuntu is an operating system built by a friendly worldwide team of expert developers. It contains all the applications you need: web browser, office suite, media apps, instant messaging, and many others. For a list of the included software, see the Software page.
  • Kubuntu is a free, open-source alternative to Windows and Mac OS X.
  • It can be easily installed alongside, or instead of Windows.

Preparing the Installation media

Getting the ISO(Disc Image):

Download it though Get Kubuntu.

Checking the MD5SUM

From Windows XP -> 7 -> 8 -> 10

Microsoft Windows does not have any built in tools for MD5SUM but they do provide a tool. How-To-Geek also provides some information regarding MD5SUM reading material or Cygwin can be installed and unix utilties can be used instead.

From Mac OS X

Open the terminal app, then navigate to the directory where the ISO is saved. Run:

md5 -r kubuntu-15.10-desktop-amd64.iso

And compare the output to the hashes page for the ISO file.

From Ubuntu Linux

The first thing to do is to make sure your in the directory with the .iso file (It will most likely be found in the the Downloads directory). The run the command ‘md5sum’. For more a more detailed explanation of MD5SUM. Then running the command ‘md5sum’:

md5sum kubuntu-15.10-desktop-amd64.iso

Windows 7/8

USB/Flash Drives

For a GUI (Graphic User Interface) we use UNetBootin.

If you choose the Diskimage option you use the ... button to select your downloaded ISO. Then click OK.



Pay special attention when selecting the right USB device under ‘Drive’

You can use unetbootin to download the ISO(image file) automatically or it can be downloaded at Get Kubuntu.


The recommended tool for you to use is ImgBurn. There is an excellent tutorial written by the Admin on the ImgBurn forums. It can be found here.

Existing Kubuntu Install

USB/Flash Drives

Since UNetBootin is a cross-platform application we will be using the same instructions from USB/Flash Drives


Be extremely careful to set /dev/sdX to the right value, if you point it to your hard drive you will wipe the disk.



Look for More actions... click it and then pick Burn image... from the list of actions


Then you select the ISO(Disk Image) that you want to burn to the DVD from your computer.


Most torrent clients and browsers store your downloads in the ‘Download’ directory.


Most of the default settings for K3b for DVD burning do not require any changes.

Other Linux Distributions

GNOME Environment

USB/Flash Drives

For a GUI(Graphic User Interface) we’ll stick to using this tutorial: USB/Flash Drives



For Linux Distributions that use GNOME we’ll be using the default DVD burning tool Brasero.

KDE Environment

You can follow the same instructions as a Existing Kubuntu Install

Install Process


You will need to press a special key on the keyboard in order to boot from your chosen Installation Media. Ex: Esc, F2, F10, F12, or Del it all depends on the OEM(Original Equipment Manufacturer)

First we’ll need the Kubuntu Disk Image(ISO) from here: Preparing the Installation media


When the installer starts you will see these options:

  • Try out Kubuntu without changing anything on your computer.
  • Install Kubuntu on your computer.


Fro the best result, ensure that:

  • Your computer has enough room for Kubuntu and your data (your songs, pictures, videos, and documents).
  • Your computer is connected to the Internet so that you can download updates and third-party software during the installation of “Kubuntu”.

Include this third-party software: includes software that either does not follow the Open Source model or the Ubuntu Philosophy, but is safe for use on your system.

Download updates while installing: will ensure that you have the latest bug and security fixes included and applied once the installation is complete.

Disk Setup

This is where you choose how to organize your hard drive. This step is the most complicated and consequential in the entire installation process, so take your time.


You will be able to change your mind and go back until the Install Now button is clicked

The following sections are some possible installation scenarios you might choose. Each of these choices points to a page or series of pages with more details. For each option (except Manual), the installer asks which hard drive to use. After choosing, you will see a before and after layout on that hard drive.


This will resize the partitions for you and install Kubuntu on the free space. With this option you can create what is called a dual-boot and choose which OS to boot into at startup.


This is available only at least 25GB are free.

Use entire disk

Using this option the installer will create two partitions on your hard drive; one for most of the content, including the root and home directories, and one for the swap.



This optio will completely erase your hard drive. You will lose any operation systems(Windows, Mac OS X, Linux, etc.

Use entire disk and set up LVM

Use entire disk and set up encrypted LVM

When using Manual to set up your system as you would like it, keep these thoughts in mind:

  • The root ( / ) directory needs at least 25 GB of space.
  • The home ( /home ) directory needs as much space as you will need for your files, music, pictures and documents. So it is best to use the remaining space for the home partition, unless you are going to have a dual boot. So it is best to use the remaining space for the home partition, unless you have going to dual boot.
  • Swap space of at least half of the available RAM is recommended. For instance, with 8 GB of RAM you should make the swap have at least 4 GB.


If you have a Windows 8 sticker on your machine you might need to make a separate EFI partition with a fat32 filesystem.

For more detailed information regarding the Disk Setup of a Linux system you can check the DiskSpace page.


During this step you get to pick the Region where you live and then the Timezone of the location in that Region. An example would be that I live in New York, so my Region is North America and my Timezone is New York (EST).



This is the step that will set up your keyboard’s language or, if applicable a different version of the language. For example, there is a Cherokee American English setting as well as different setups with special keys used in certain languages; in Kubuntu we try to make the use of the system easy for everyone!


User Info

At this step of the installation you will be putting in user information like your name, username, and password. The password will be your key to logging into your new installation as well as installing new software, updating your system, and more, so keep it written down somewhere!
