Detailed installation history of Ubuntu 20.04 LTS

This article records the creation of a USB boot disk and system installation. System configuration is covered in a separate article.

Materials Needed:

• 4GB or larger USB flash drive
• Ubuntu 20.04 ISO file (download from Ubuntu official website)

1. Make a USB boot disk

Use an old version of Ubuntu to create an Ubuntu 20.04 boot disk

The following reference to the Ubuntu official tutorial requires Ubuntu 14.04 or above. I use Ubuntu 16.04

Enter Startup Disk Creator in the startup bar to open the system's built-in startup disk creation tool

It will automatically detect the iso file in the Downloads folder and the USB drive inserted into the computer

Back up the files in the USB drive, click Make Startup Disk, and a dialog box pops up asking "Do you want to write the image to the device? Click OK. After writing is complete, you can use it as a startup disk to start installing the system.

Use Windows to create Ubuntu 20.04 boot disk

Let me dig a hole first. I'll install Windows and then write it.

2. Install Ubuntu 20.04 using the boot disk

Setting up the BIOS

Insert the USB disk made as the boot disk into the computer on which you want to install Ubuntu 20.04, restart the computer, and enter the BIOS system before the system is loaded (press F2 or F12 before the welcome interface of the current computer system appears. The keys are different for different computers, and some will be displayed in the bottom line of text prompts on the boot interface; you can go online to check the key to enter the BIOS corresponding to your computer model, or try pressing F2 and F12 at the same time). After entering the BIOS, use the left and right arrow keys on the keyboard to switch to the Boot page (different computers have different BIOS systems, so the operations may also be different), then press the up and down arrow keys to select the USB HDD line, which is the USB boot disk we plugged into the computer.

Then adjust the Boot priority order. My computer's BIOS uses F6 to move up options. There will be prompts for the operation keys on the interface. You can check which key to use in your computer's BIOS. Some computers can directly select a boot to start directly. Move the USB boot disk up to the first position.

Then use the left and right arrow keys to switch to the Exit page and select Exit Saving Changes to save the setting changes and exit. A confirmation box pops up asking "Do you want to save the settings changes and exit?" Select Yes to confirm.

The system automatically restarts and then enters the startup selection interface. Just use the default first-line option Ubuntu and press Enter (this interface will only stay for a few seconds, and the item where the cursor is currently located will be automatically selected and started if no operation is performed).

Start installing Ubuntu 20.04

Enter the installation wizard interface and select the language in the left box. After selecting the language, you can choose Try Ubuntu to try out Ubuntu 20.04 first. The operations you make will not affect the existing system on the computer. If you don’t want to install it, you can shut down the computer, unplug the USB drive and restart it, and you will return to the original system.

After trying the system, you can select Install Ubuntu 20.04 LTS on the desktop to start the installation. If you stay in the installation boot interface, directly select Install Ubuntu. The effects of the two are the same.

Select the desired system language and click Continue to enter the next step of keyboard settings. The default is the QWER standard keyboard. If there is no problem, you can directly click Continue to enter the next step.

After setting the language and keyboard, enter the update and software installation selection page. Choose Normal installation or Minimal installation according to your needs. The former is a standard installation, and the latter is a minimal installation, which only installs the most basic software and will install faster. The two options in Other options also depend on your needs. If you choose the two options here, you need to be connected to the Internet to install.

Choose dual system installation or overwrite the original system

Click Continue to enter the system installation type selection. The first option is to erase the original system; the second option is to install a dual system, which will retain the original system; the third option is to erase the entire disk; the fourth option is a custom installation. I choose the third option here, erase the entire disk and install Ubuntu, and click Install now.

A confirmation interface will pop up to show the disk changes. After confirming that all files on the computer have been backed up, click Continue to start the installation.

Select the time zone, set the account name and password, and click Continue to start installing the system.

After the installation is complete, you will be prompted to restart the system. Select Restart and you will be prompted to unplug the boot disk and press Enter. Then you will enter the Ubuntu 20.04 welcome interface and the installation is complete.

3. Optional Configuration

I'm a girl
! ! ! ! ! !
#%@#$@#I finally installed the Chinese input method! I have something to say! ! !
After installing the system, I started to install Sogou input method, but found that 20.04 removed qt4, and the installation dependency of Sogou input method could not be solved. Then I tried to install other input methods. When configuring language support, a message popped up saying that I had not authenticated. Then I suspended the system and logged in again, and there was an authenticate window stuck in the upper left corner of the screen, and clicking authenticate or cancel didn't work? ? ? Then I restarted the computer and logged into the system but the screen was black? ? ? The other ttys are available, but the visual user interface is black, and I can only control a mouse cursor, which is wandering around on a black screen? ? ? And the sound of the laptop is getting louder and louder. I don't know if it's because my computer performance is not good or the graphics interface is buggy and can't be calculated. sigh
Then I reinstalled the system and it returned to normal.

Finally, I will mention here how to adjust the system display text size, and write another article to talk about the installation of Chinese input method. There are two ways to adjust the size, and the second one is recommended.

DisplaysAdjust screen magnification

Click the status bar in the upper right corner and enter the settings interface from the drop-down menu. Find Displays in the left column of the settings interface. The fourth row of Built-in display, Scale, is the screen magnification ratio, but there are only two integer options: 100% and 200%. After switching to Fractional Scaling in the fifth row, the fourth row will have five options: 100%, 125%, 150%, 175%, and 200%. However, the screen display quality does deteriorate after selecting a fractional size, so it is recommended to use the following method. By the way, in the top title bar of this interface, you can see Night Light on the right side of Displays, which can adjust the warm red light at night. But after turning it on, I feel that it is still a bit too red when adjusted to the weakest level. It is still recommended to use redshift.

Universal Access Adjust text enlargement

The method to open the settings is the same as above: click the status bar in the upper right corner and enter the settings interface from the drop-down menu. Find Universal Access in the left column of the settings interface. The second line of Seeing on the right is Large Text. When it is turned on, the system text will be enlarged. There are some magnification functions in the fourth row of Zoom that you can try, such as a magnifying glass that follows the cursor.
