What happens to my computer when I reinstall Ubuntu?

When we do the installation of an operating system, what we do is copy certain key files from the USB to the main disk. In this way you are given the necessary information so that all the system files are installed. This is the common way to install an operating system and is almost always done from scratch.

For this reason, all the files are deleted , since the same installation wizard makes a quick format to our unit. Allowing it to be clean of all viruses or corrupted files, personal data is lost in this type of installation, so it is not recommended for cases in which information cannot be lost.

In this particular case, what we are doing is a similar process, but eliminating the factor that deletes the files. When we reinstall a system, we do not format the hard drive, but instead replace the original files with new ones , thus allowing errors to be corrected.

Depending on the version of Ubuntu that we are going to install, we may have a different tool. So we must take into account what our needs are, in order to choose the best version.
