How do you open the Ubuntu system?

To open the Ubuntu system, you need to follow these steps:

1. Turn on the computer and access the Grub boot menu. In most cases, you can press the F2, F10, F12, or Delete key when starting up the computer to enter the boot menu. If you are unsure which key to use, refer to the documentation from the computer manufacturer.
2. Select the Ubuntu operating system in the Grub menu. It is usually listed at the top of the menu.
3. Press the Enter key to start the Ubuntu system.
4. If your computer has only the Ubuntu system when it starts up, it will directly go to the login screen. On this screen, enter your username and password, then press the Enter key. If it is your first time logging in, you may need to create a new user account.
5. Make sure that the username and password you enter are correct. If entered incorrectly, the system will display an error message and prompt you to re-enter.
6. Once you successfully log in, you will enter the Ubuntu desktop environment, where you can use various applications and perform different tasks.

These steps should help you open the Ubuntu system. If you encounter any problems or difficulties, please refer to the official Ubuntu documentation or search for solutions to related issues.
