Preparation

Note: This article takes the installation of Ubuntu 23.04 as an example.

The preparatory work needs to be done on another system, and here we will perform the following operations on Windows 10.

1. Download Ubuntu image

Open the official website of Ubuntu: https://ubuntu.com/download/desktop

After entering the page, click the [Download] button on the right to start downloading the ISO system image file of Ubuntu.

2. Creating a USB bootable drive

1) Download Rufus writing tool and open it after the download is complete.

Download link: https://drive.google.com/file/d/1Z-sMEl91ItJDwfzJHgPoWqbPZXG0-qAv/view

2) Insert the USB flash drive that will be used as a bootable disk. If there are any files on the USB drive, please make sure to back them up to prevent data loss. Once the USB drive is inserted, the capacity of the USB drive will be displayed in the device area.

3) Click "SELECT" and then find the downloaded Ubuntu system image file, and click "OPEN".

4) Click "START" to write the Ubuntu system image to the USB drive.

 If the following prompt appears, select "Write in ISO image mode" and click [OK].

5) After the writing process completes, you can safely remove the USB flash drive.
