Why try Kubuntu?

There are many good reasons to install Kubuntu! Including:

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

Preparing the installation media

Checking the MD5SUM

Doing this will make sure your download completed fully and has given you a fully working ISO to boot and perhaps later install from.

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

Microsoft Windows does not have any built in tools for MD5SUM but they do provide a tool for checking the MD5SUM. How-To-Geek also provides some reading material if you want to understand the technology behind MD5SUM if you like.

From Mac OS X

.. todo: TODO for 15.10 cycle:

It should be:

md5 /PATH/kubuntu-15.10-desktop-amd64.iso

output would be:

MD5 (/PATH/kubuntu-15.10-desktop-amd64.iso) = 2e9967a25d87f7c685c63101eddb17d6

List of UbuntuHashes:

From Ubuntu Linux

The first thing to do is to make sure you're in the directory with the .iso file (most likely in the Downloads directory). Then run the command 'md5sum': For more complex use of MD5SUM check this out

   md5sum kubuntu-15.10-desktop-amd64.iso

Windows 7/8

USB/Flash Drives

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

You can use UNetBootin to download the ISO(image file) for you or download it though Get Kubuntu.

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

UNetBootin Windows 8
Pay special attention when selecting the right USB device under 'Drive'


The recommended tool to use is ImgBurn There is a excellent how-to on the ImgBurn forums by the admin here.

Existing Kubuntu Install

USB/Flash Drives

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

You can use UNetBootin to download the ISO(image file) for you or download it though Get Kubuntu.

Using the command line we use the 'dd' command.

Insert your USB drive into your computer and find out the drive allocated to it using: lsblk
Then format the USB drive with the 'dd' command:
sudo dd if=Downloads/kubuntu-15.04-desktop-amd64.iso of=/dev/sdX

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


For making a DVD we recommend the awesome KDE tool K3b


Look for More actions..., click it then pick Burn Image... from the list of actions.

K3b Image Selection

Then you select the image (iso) that you want to burn to the DVD from your computer.

Most torrent and browsers store your downloads in the 'Download' directory.

Most of the default setting for K3b for DVD burning are fine.

Other Linux Distributions

GNOME based

USB/Flash Drives

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

You can use UNetBootin to download the ISO(image file) for you or download it though Get Kubuntu.


KDE based

If your using a Linux Distribution that uses KDE you can follow the Kubuntu instructions as K3b is provided in every KDE based Distro (Distribution).

Install Process

First, you will need to download Kubuntu. See Get Kubuntu

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)

Install Welcome Screen

When the installer starts you will see these options:

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


For 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 as Kubuntu is installing.
Install Prepare Screen

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 install 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 if at least 25GB can be freed.

Use entire disk

In this scenario the installer will create two(2) partitions on your hard drive. One(1) for the root, home, and everything else and one(1) for the swap.

Entire Disk option
This option will completely erase your hard drive. You will lose any operating systems (Windows, Mac OS X, Linux, etc.) and all your data that is stored on that drive.

Use entire disk and set up LVM

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

Manually setting up your hard drive
  • The root ( / ) directory needs at least 25 GBs 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 have going to dual boot.
  • Swap space of at least half of the available RAM is recommended. For instance, with 8 GBs, make the swap with at least 4 GBs.
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.

Setting your timezone


This is the step that will set up your keyboard's language and, if the language has it, 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 countries; in Kubuntu we try to make the system easy for everyone!

Keyboard Screen

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!

Entering your username, password, and hostname

Return to Kubuntu Home
