Installing Kubuntu

September 3, 2006 § 4 Comments

This post outlines instructions for installing Kubuntu after successfully booting the live cd.

Step 1: Click on the install icon on the desktop. The welcome dialog of the installer is displayed.

Select English as the language of choice and click on Continue.

Step 2:

In the next dialog, select and set the timezone and country.

Step 3: Select the keyboard layout in the next dialog.

Step 4: Set the user name and password which you will use on a regular basis.

Step 5: The next step is to select the partitions to install Kubuntu to.

A common scenario will be making space to install Kubuntu onto a system which already has another operating system.

A simple installation of any linux system requires at least the following two partitions:

1. a root (/) partition for the entire system. This will also contain the user files in the /home directory. For a reasonably usable system a root partition of at least 10 GB is recommended.

2. a swap partition, which is used by linux as additional memory. Generally it is a good idea to make the swap partition double the amount of physical RAM present in the machine. So if we have 1 GB of RAM, then a swap partition of around 2GB is a good idea. Having a relatively larger swap partition (as in 2 GB) is beneficial if we want to remaster our own custom linux CDs also.

3. Additionally, its better, but not necessary to have a separate partition for user files in the /home directory. For our simple installation, we’ll just concentrate on a single root partition.

But if we have the following scenario: the entire hard disk is divided into four partitions: C, D, E, and F and we have Microsoft Windows installed. Then how do we proceed?

Suppose we have E and F drives as FAT32 partitions which we want to clear and install Kubuntu.

Since we have 4 partitions, they might be represented as





The jump in numbering from hda1 to hda5 signifies that the remainder partitions are logical partitions.

Once we are certain that we will use the space occupied by hda7 for our install, delete it in the partitioning step and create two partitions in the free space generated: one for swap and one for root.

In the Prepare disk space dialog, select Manually edit partition table since we want a custom partitioning setup for our install. Click on Continue.

Step 6: The next dialog shows the available partitions.


In the figure above, there are 5 partitions already defined.

We will be installing Kubuntu onto /dev/hda9, which is already a formatted reiserfs file system. In order to install linux, we require a native file system such as ext3 or reiserfs.

If we were going to delete the E drive of our Windows installation, we do so here. Let’s say we have a 30 GB E drive.

Select the partition and click on the Delete icon. We will now have 30 GB free space. Note that this is a permanent operation, and we should delete a partition only if we are sure that all information has been backed up. Perform this step carefully!

In the 30 GB free space created, we can now create a 2 GB swap partition, a 12 GB root partition, and a 16 GB home partition. Format the partitions after creating them.

Step 7: However, in this installation walkthrough, we are going to install Kubuntu onto hda9 as a single root (/) partition which is already formatted as reiserfs.
Set the mount points for (/) and swap as shown in the dialog below.

Prepare Mount Points

Click on Continue to proceed further.

Step 8: A final confirmation dialog is displayed. Ensure that all options have been selected properly, and click on Install to commence the installation.


The installation begins. During the installation process, the GRUB bootloader is installed. GRUB will create menu entries for the different operating systems already installed on the machine. So if we have an existing Windows or any other GNU/Linux system installed, or have an existing bootloader installed, the installation process will replace it with a new GRUB. For more information on choices for bootloader, you are encouraged to read through the Kubuntu community forums.

After the installation finishes, either continue using the live cd, or reboot as desired.

    Does Kubuntu actually supports Reiserfs?

  • csrins says:

    Haven’t actually tried creating a Reiserfs partition during Kubuntu install. However, Kubuntu installs fine to an existing Reiserfs partition.

    Needs looking up.

    I just tried creating a Reiserfs with Kubuntu and the laptop locked up, it probably couldn’t find /sbin/mkfs.reiser4. The file system was already a Reiserfs, but I felt it should be reformatted anyway. It seems Ubuntu doesn’t have a problem with this at all. I’m betting the reiserfs commands are missing from the Live CD. I suppose one could do the partitioning and formatting with Knoppix then install Kubuntu afterwards, being sure you installed the Reiserfs tools properly.

  • csrins says:

    Edgy (6.10) is able to create a reiserfs system for both Ubuntu and Kubuntu. But if an existing partition is used, then the installer does not proceed further giving an error “No root partition”. This is a known recorded bug, and the workaround is to delete and recreate the partition. This only occurs for reiserfs, not for ext3.
