Problems encountered during Ubuntu Installation

I have encountered some problems when installing Ubuntu. First, I declare that I am a linux hacker and I have never touched it. Because I am about to graduate soon, I have been recruiting many campus jobs recently. I am very grateful to have some knowledge about Linux, so I was eager to install Linux. Step 1: Download the linux image file http://www.ubuntu.org.cn/official network address Step 2: Use winRAR or another tool that can open the image file to open the downloaded Ubuntu and copy the wubi.exe file, and put the ISO file in the same directory. Step 3 of www.2cto.com: Click wubi.exe, set the location of the partition to be installed, and allocate the size and space. Wait until the boot program is complete and restart. Step 4: Select ubuntu after restart to complete installation! I encountered a problem. I didn't know how to install it at first. I watched a lot of videos and used many tools. The error is always returned, and I don't know why, that the system's valid media files cannot be found, and so on. At first, I directly click wubi in iso to install wubi, which is also the same error. Finally, I had to test wubi and put it in the same directory as ISO.
