In many cases, it is more convenient to configure a virtual machine and install the necessary programs on it than to do it on a real computer. First, when installing on a “clean” virtual machine, there is a greater chance that everything will pass without errors, since There will be no conflicts with already installed programs. Secondly, the virtual system can be easily “rolled back” to the previous state if something went wrong. Thirdly, all virtual machine data is stored as files on your computer, so it is easy to copy it somewhere else and, for example, take it with you on a business trip to work on any real computer in a familiar virtual environment. Fourthly, virtually any operating system (OS) can be installed on a virtual machine, including one that does not coincide with the system installed on your computer.

The operating system on your real computer will be called the host system , and the one installed on the virtual machine will be called guest or virtual .

Installing Oracle VirtualBox for Microsoft Windows
First, install a special program that will allow us to create virtual machines.Oracle VirtualBox
In any browser, open the official website virtualbox.org . Let's follow the link Downloadsand download two files to your computer:
  • VirtualBox 6.0.6 platform packages
  • VirtualBox 6.0.6 Oracle VM VirtualBox Extension Pack
(the numbers indicate the version number and may be different).
Run the first one. All settings leave the default. We will answer yes to all questions. During the installation, the network will be unavailable for some time (so do not start the installation if you have, for example, some file being downloaded at this time).

Upon completion of the installation, you must run the second file for execution and also answer all questions in the affirmative.

We indicate the memory size of 1024 MB (it’s important here that there is enough memory left for the main system; therefore, if the amount of RAM in your computer is less than 2 GB, then change the input value so that it is slightly less than half of the total memory).

Click the Next button (fig. 2).

In the same settings dialog box on the left, we’ll go to the Shared Folders section and on the right, click the small button with the plus sign to add a shared folder with which you can copy files from the host system to the virtual machine and back.

Check the Auto-connect checkbox and press the OK button twice .
