In addition, you should also make a note of any software applications that you have installed on your computer. This will make it easier to reinstall them after you have installed Ubuntu.
3. Create Installation Media
To install Ubuntu on your computer, you will need to create installation media. This can be either a bootable USB drive or a DVD. Here is how you can create a bootable USB drive:
- Download the Ubuntu ISO file from the official Ubuntu website.
- Insert a USB drive into your computer with at least 4 GB of free space.
- Download and install a tool to create a bootable USB drive, such as Rufus or Etcher.
- Run the tool and select the Ubuntu ISO file and the USB drive as the destination.

Alternatively, you can create a bootable DVD by burning the Ubuntu ISO file to a DVD using a tool such as ImgBurn.
Once you have created the installation media, you are ready to proceed with the installation of Ubuntu on your computer.
1. Boot from Installation Media
To install Ubuntu, you will need to boot your computer from the installation media that you created in the previous step. Here is how you can do it:
- Insert the USB drive or DVD into your computer.
- Restart your computer.
- Press the key that takes you to the boot menu during the startup process. This key varies depending on the computer manufacturer but is usually F12 or Esc.

Once your computer boots from the installation media, you will be presented with the Ubuntu installation menu.
2. Select Installation Options
After booting from the installation media, you will be prompted to select various installation options, such as language and time zone. Here are the steps to follow:
- Select your preferred language from the list of available languages.
- Select your time zone from the map or list of available time zones.
- Choose your keyboard layout by selecting the country where it was made or the layout that matches your keyboard.
