How to migrate from Windows to Linux?

1|center|600

If you are reading this post, it’s because for one reason or another, you decided to try Linux. You’ve thought it over and concluded that you want to give Linux a shot.

But… where to start? Currently, there are thousands of videos from YouTubers recommending X or Y distribution or Linux “flavor.” However, here we will focus on one specific Distro: Kubuntu.

The reason for choosing this Distro is the vast amount of documentation available. Even if you don’t want to read it all, it will be easier for an AI like Gemini or ChatGPT to correctly answer any questions about the system.

I am aware there are other distributions with a more “gamer” or “user-friendly” profile; however, the general process and workflow will be practically the same for any distribution:

Creating a Bootable USB

For this first step, we will refer to a previous post where we covered how to install VENTOY on our PC: Bootable USB Preparation Tutorial

Once this process is finished, we can proceed with the Linux installation on our computer.

Installing Kubuntu

For this section, I’ve included a silent video where you can follow the step-by-step instructions:

  • With the USB connected and just as you turn on the computer, access your BIOS and select to “boot” from your USB drive.
  • Then select the option “Try or Install Kubuntu” and wait for the installer to load.
  • Once there, select your language and country.
  • Select Install Kubuntu to install directly, or Try Kubuntu if you want to get familiar with the system before installing.
  • We will select Install.
  • Select your region and keyboard layout.
  • There are 3 installation modes: full, normal, and minimal. I will choose normal installation. To save time later, I will check the option “Download and install updates after installation.”
  • Then, select your hard drive.
Watch out for your hard drive!
Before proceeding with the Linux migration, make sure to have a full backup. Formatting the wrong partition is a common mistake.
  • Since this is an empty disk, it suggests erasing it completely. If you want to keep Windows, it will show the option “Install Alongside Windows,” allowing you to select the disk size you want to assign to each.
  • Click next and pay attention here: set your username and a password. Do not forget this password, as you will use it for everything in the future.
  • You can check the option to log in automatically, though I personally prefer not to.
  • Finally, it shows a summary of the processes; confirm, and the system will begin installing.
  • Now is a good time to go grab a coffee.

First Boot of Kubuntu

Once finished, a window will appear with the option to restart. It will ask you to remove the USB and press Enter to continue.

After that, if you installed alongside Windows, a menu should appear where you can choose which system to enter; by default, it will enter Kubuntu after 10 seconds. You can press Enter to skip the wait.

Enter your password, and finally, you are in Kubuntu.

The first thing we’ll do to keep our system protected is to enable automatic updates:

  • Open the System Settings app and search for Software Update.
  • Select Automatically, and here you can choose the update frequency.
  • I recommend enabling the “Use offline updates” option, as it will install updates only when you decide to shut down or restart.
  • To update manually, open Discover (the App store). Go to updates, click refresh, and pending updates should appear.

This concludes the installation. Later, we will see how to customize the system and prepare it for the FedoGamer script.
