If you need to install an operating system or do some maintenance work on your computer, you need to select the CD menu option at startup. However, for some uncommon computer brands or hidden menus, it may be difficult to choose the option to start the CD. Here are some useful tips to help you find and choose the right menu option to start the CD.

First of all, when starting the computer, you should choose the appropriate button according to the brand and model of the computer and enter the startup CD menu. Some commonly used buttons include Esc, F2, F9, F 12, Del or unique buttons in different computer brands to start the menu. These buttons can help you enter the BIOS setup or startup menu, where you can select CD menu options.

If you don't know the brand and model of your computer, or even if you press the correct button, you can't enter the startup CD menu, then you can try the following steps:

Restart the computer and enter BIOS settings. In the BIOS settings, find the startup option and use the CD as the preference.

Restart the computer and try to use different buttons to enter the startup menu. Sometimes different computer brands and models use different buttons. By searching for relevant information, you can find the appropriate menu option to start the CD.

If your computer doesn't support the startup CD menu option, you need to use other startup methods, such as booting from a USB device or installing with imaging software.

In a word, it is an important step to choose the correct menu option of the startup CD to repair the computer or install the operating system. If you encounter difficulties, you can follow the tips and steps to try to solve the problem. The best choice is to find the most reliable startup CD menu option by searching the relevant information of computer brand and model.
