+## `Ubuntu` How to install
+
+There are two main ways to install Ubuntu: on a laptop/desktop and in a virtual machine.
+
+### Installing Ubuntu on a Laptop/Desktop
+
+Before we begin, here's what you'll need:
+
+- A laptop or PC with at least 25GB of storage space.
+- A 4GB or larger USB stick/flash drive.
+- An Ubuntu ISO file. You can download it from the [official Ubuntu website](https://ubuntu.com/download).
+
+#### Create a bootable USB stick
+
+To install Ubuntu on your computer, you need to create a bootable USB drive with the Ubuntu ISO file. Here's how you can do it on Windows:
+
+1. Download the Ubuntu ISO file from the [official website](https://ubuntu.com/download).
+2. Download and install [Rufus](https://rufus.ie/). It's a free and open source USB stick writing tool that you can use to create a bootable USB drive.
+3. Insert a USB drive with at least 4GB of space into your computer.
+4. Open Rufus and select the USB drive you inserted.
+5. Select the Ubuntu ISO file you downloaded.
+6. Keep the rest as default and click "START".
+7. Rufus may ask for additional files to complete writing the ISO. If this happens, select **Yes** to continue.
+8. You'll be alerted that Rufus has detected that the Ubuntu ISO is an *ISOHybrid image*. Keep *Write in ISO Image mode* selected and click **OK** to continue.
+9. Rufus will warn you that all data on your selected USB device will be destroyed. Double check that you've selected the correct device and click **OK** when you're sure.
+10. Wait a few minutes for Rufus to write the ISO to your USB stick.
+
+If you are using a different operating system, you can use an alternative tool like [Etcher](https://www.balena.io/etcher) to create the bootable USB drive.
+
+#### Install Ubuntu
+
+1. Restart your computer and enter the BIOS by pressing F2 or F10 or F12 (depending on your computer) when the logo appears.
+2. Go to the "Boot" tab and select the bootable USB drive as the primary boot option. Save and exit the BIOS. Your computer will restart and boot into the Ubuntu installation process.
+3. Follow the on-screen instructions to install Ubuntu on your computer.
+4. In the "Type of Installation" page, select "Erase disk and install Ubuntu" if you want Ubuntu to be the only operating system on your hard drive.
+5. Review your configuration then click "Install" when you are sure. Note that once you begin the installation process, you cannot return to this point.
+6. Once the process finishes, you will be asked to restart the system. Remove the USB disk and press enter. Your system will reboot and start Ubuntu.
+
+You've successfully installed Ubuntu on your laptop or desktop computer. Enjoy exploring this powerful and user-friendly operating system!
+
+### Installing Ubuntu in a Virtual Machine via VirtualBox
+
+If you don't want to install Ubuntu directly on your computer, you can also install it in a virtual machine using VirtualBox. Here's how to do it:
+
+1. Download and install VirtualBox from the [official website](https://www.virtualbox.org/).
+2. Download the Ubuntu ISO file from the [official Ubuntu website](https://ubuntu.com/download).
+3. Open VirtualBox and click "New" to create a new virtual machine.
+4. Follow the on-screen instructions to create a new virtual machine. Fill in the appropriate details.
+5. Fill the basic details of your virtual machine.
+   - Name: Ubuntu 22.04 (depends on your version)
+   - Folder: Select folder where your virtual machines will be stored
+   - ISO Image: Ubuntu ISO file you downloaded
+   - Type: Linux
+   - Version: Ubuntu (64-bit)
+6. Create a user profile with a username and password for the automatic installation.
+7. Specify the resources for your virtual machine, such as RAM and CPU usage, and the size of the hard disk.
+   - Base memory: At least 4GB
+   - Processors: 4 CPUs
+   - Hard disk: Create a new virtual hard disk
+   - Disk size: At least 25 GB
+8. Review the summary of your machine settings and click "Finish" to create the virtual machine.
+9. Start the virtual machine and follow the on-screen instructions to complete the Ubuntu installation.
