Requirements

In order to practice, we will install Kubuntu following these requirements and tools:

• 1 x USB flash drive >=8GB as bootable media
  
• 1 x USB flash drive >=32GB as hard disk formatted as GPT
• 1 x first partition EFI 200MB
• 1 x second partition SWAP 2GB
• 1 x third partition ROOT 28GB at slash
  
• UEFI-based method
  
• dualboot method automatically

This tutorial is designed for beginners and people with minimum computing knowledge. If you have practiced and grasped this safe-for-newbie method, you will soon understand to do it on a hard disk drive or SSD even the external ones.

Download Kubuntu

In order to install Kubuntu, you should have Kubuntu image file. Download Kubuntu 22.04 here. If you don't know how to, please read Kubuntu Download Guide. 

Making Bootable Media 

After downloading Kubuntu image, you should make a Kubuntu bootable. Follow our Bootable USB Making Guide.

Booting Your Computer

After making bootable, you should boot the bootable USB on your computer. Follow our ThinkPad Booting Guide. Other brands will be able to follow by adapting it.

Enter LiveCD

Once booted up properly, you will see Kubuntu LiveCD offering two choices either to "TRY KUBUNTU" or "INSTALL KUBUNTU". 

Begin Installation

Double-click Install Kubuntu at the desktop to start the Kubuntu 22.04 system installer.

Step 1. Selecting Language

Select English and click Continue.

Step 2. Selecting Keyboard Layout

Select English (US) and click Continue. This still can be changed later once the system has been installed.

Step 3. Selecting Network

Select "I don't want to connect..." and click Continue. 

Step 4. Selecting Software Updates

Select "Normal Installation" and click Continue. 

Step 5. Selecting Manual Disk Partitioning

Select "Manual" from the disk partitioning choice.

Step 5A. Create First Partition

To our installation, our USB flash drive is /dev/sdc and yours might be different so please adapt it yourself. 

1. Select free space under /dev/sdc.

2. Click Add...

3. On the dialog, change size to 200 MB

4. Change Use as to EFI SYSTEM PARTITION

5. Click OK and you created an EFI partition at /dev/sdc1.

Step 5B. Create Second Partition

Because we created EFI partition, now the free space is decreased.

1. Select free space under EFI partition /dev/sdc1.

2. Click Add...

3. On the dialog, change Size to 2000 MB (two gigabytes)

4. Change Use as to SWAP

5. Click OK and you created a SWAP partition at /dev/sdc2.

Step 5C. Create Third Partition

Because we created two partitions already, now free space is also decreased accordingly to about 28GB left.

1. Select free space left.

2. Click Add...

3. On the dialog, don't change Size and let it be as is.

4. Change Use as to EXT2 Filesystem. 

NOTE: If you install Kubuntu into hard disk, change use as to EXT4 Journaling Filesystem instead.

5. Change Mount point to slash ( / ).

6. Click OK and you created a ROOT partition at /dev/sdc3. 

To this point, you have created three partitions required for Kubuntu in the USB flash drive.

Step 5D. Place the Bootloader

For UEFI computers, the bootloader of an operating system is placed at its EFI partition. 

1. See Boot Loader section under the partition list.

2. Change the selection into /dev/sdc1. 

NOTE: change this according to where your own EFI partition is.

3. You should check that your EFI and your bootloader should point to the same place. In this example, /dev/sdc1. 

Step 5E. Start Installation

1. Click Install Now. 

2. Read carefully, for a dialog will show a summary of what disk partitions will be deleted and formatted. 

3. Once everything is correct and no mistake spotted, click Continue. You will jump to next section.

4. Otherwise, click Cancel and carefully correct every mistake, then repeat Step 5E once again.

Step 6. Select Timezone

Select your timezone and click Continue. For example, since we live at West Indonesia Time, we select Asia / Jakarta.

Step 7. Create Username and Password

Fill the 5 text boxes with username and password as exactly the following:

• master
• master

• master
• master

Select Login Automatically and then click Continue.

This choice of username and password is a help for beginners for it is very easy to remember and you can change it later once Kubuntu is installed.
