I wrote it for myself, I am afraid I will forget it, and I hope it will help everyone.
1. ubuntu version selection
Now (2018.4.23) the versions given on the ubuntu official website are ubuntu-16.04.4LTS and ubuntu-17.04 and the Chinese version of Ubuntu Kylin-17.10 developed by the National Defense University of Science and Technology. It is recommended to choose the version with the LTS suffix (LTS: Long Term Support, that is, long-term support). I have installed the latest ubuntu-17.04. As a result, various small bugs and many software incompatibilities can not be installed, and the experience is extremely poor.
这里建议ubuntu-16.04.4LTS
2. Preparation conditions
1. Prepare a 4g or more U disk as the system disk
2. Download the complete ISO file from the official website (note that the files you have downloaded here are correct, I myself do not know because the files are damaged, I have been It was not installed successfully, and finally re-downloaded) official website URL: https://www.ubuntu.com/desktop
3. Download the universal USB installer software, which is specially designed for making Linux system disk tools, especially easy to use! (I have used the so-called free, fool-like installation software on the market, which is not only rogue, but also cannot be installed well when installing Linux, so do not use these junk software! It will also damage the U disk!)
3. Start Installation
1. First open the universal USB installer, select the iso file and u disk of ubuntu, allocate the largest space (4098M), then click creat, and wait patiently for the completion of the production.
2. After the production is completed, restart the computer, enter the BIOS interface ("Basic Input Output System", the BIOS will be loaded first before loading the operating system, it is a set of programs that are solidified on a ROM chip on the motherboard of the computer.) Boot the boot. Item (boot) is set to U disk, that is, U disk, then save the changes and exit.
3. After that, the ubuntu icon will appear on the computer screen, directly select install ubuntu.
4. After a series of English flashes across your screen (in fact, Linux is detecting your hardware information), you will see a graphical interface that you can understand, allowing you to choose the language, time zone, etc. I emphasize that it is more important, never set an encryption password for your hard disk! Not only is it very troublesome to forget, but you also have to enter it when you turn it on. . . This is really crazy. The user login password can be set or not, that is, after setting, many software installations or access files require you to enter the user password. . .
Well, when you have selected all the options, the graphical interface will remind you to restart the computer. This time the boot item should select the hard disk where you installed the Linux system. After booting, a brand new interface appears, OK, your linux is installed!
Start your Linux trial and error journey!
