Installation is relatively simple, as long as you have a little basic knowledge of hardware, maintenance is very troublesome, and you need to have professional knowledge of software and hardware, know certain English terms and have rich experience. I have been doing computer installation and maintenance for almost eight years, and there are still many problems that I can't solve. I suggest that you start with the installation of the system, and then learn more about the hardware, such as the hardware model, which board is compatible with which hardware will be better. Finally, learn computer maintenance. Generally, hardware is not easy to maintain. If it is broken, replace it. If we use software, we will have experience in reinstalling the system directly. For example, boot into the system blue screen, the system startup file is lost or damaged, and directly install the system. For example, there is no response when booting, which is mostly caused by poor hardware access. In a word, there are many problems in computer maintenance. If you have the basic knowledge of installing the system, I suggest you learn by doing.
