What should I do if the system selection interface becomes English?

The system selection interface has become English. My system is Chinese. It should look like the picture below, but it is now in English.

When you call Windows in the Chinese version of the system, you can start Windows. When you use the related menu options of the Manager (Boot Manager), you may find that the language of the menu option is not Chinese. The reason for this is that Boot Manager needs to read the language information from the BCD and record it in your BCD. If the menu language information is set incorrectly, there may be a problem that the language of the Boot Manager related menu does not match the expected language.
If you first install the Chinese version of Windows and install the English version of Windows to form a dual system coexistence, then the menu language information of the BCD record will be based on the last installed English version. And this problem just affects the operating system's selection menu language information.
To solve this problem, you can solve it by command line:
1, you can open the CMD command prompt with administrator privileges (right click on the shortcut of the command prompt, select in the right-click menu) “Run with administrator privileges ")

2, enter and execute the following command:
BCDEDIT -SET {BOOTMGR} LOCALE ZH-CN

The above command can be started The operating system selection menu, that is, the display language of the selection menu of which operating system needs to be activated when multiple operating systems coexist, is modified to Simplified Chinese
