What is a virtual machine?

Users of personal computers have a huge set of tools, but I use it not all.

With the help of some functions, it is possible to increase the usability of a PC and provide reliable protection. One of the options to improve the system, is to install a virtual machine.
What is a virtual machine? Is the emulation of the operating system, but if to explain in simple language, you can run another OS as a normal program.

No need to reinstall Windows, all the data remain intact, but at any moment you can open the operating system in a window.

Why you need a Windows virtual machine?
This technology will be used for different purposes. Some people are afraid to run downloaded from the Internet files, so run them on an emulated OS.

This is the real way to check data for viruses without risks. Running the VM separately, whatever you installed programs, it does not affect the main operating system.

In addition, such a useful tool is used to run programs and games that are not on older versions of Windows or created under Windows 7,8,10, Vista and so on.

Not everyone knows that it is at all possible, and that even the most dangerous Internet viruses have penetrated into your system, it's perfect.

The installation of the virtual machine is not time consuming and to start serious knowledge is required. The special installers made for beginners, but they need to put specific configurations, so be sure to use our instructions provided below.

How to install a virtual machine?
To do this, you will first need to download the virtual machine. Programs for this, the most popular is VirtualBox, Hyper-V, Virtual PC and VMWare.

Which operating system to boot up to you, some people put the modern OS to gradually get used to it.

Of all the options available, I liked the virtual machine is Virtualbox. To download must only of. website, install and launch.

When installing and opening the VM, select "Run as administrator" to not show unnecessary errors.
To show a good example we have already downloaded the virtual machine VirtualBox, installed it and launched.

Now, there are:

1.After the first run, just press the "Create"button.
2.The user will need to choose the operating system for the virtual machine. There are many options, the version is also choose at its sole discretion. The name can be arbitrary.
3.Next you want to set the size of memory. Note that the VM will consume PC resources, so you need to leave the part under the main OSes. If you are installing on the Windows of the eighth version, allocate at least 1 GB., otherwise it will run slowly.
4.Similarly, to set the amount of memory from the hard disk that will be used by the VM.
5.We choose create a new virtual hard disk, so the next step asking you to choose its type. We will not describe each of them, just choose the first option.
6.Even here you want to choose a format storing information on the hard disk. Dynamic virtual disk allows not immediately occupy the entire space.
7.The last step of creating a virtual machine is an indication of the amount of allocated memory. And quite a few gigabytes, but if you plan to install multiple OS's to load a bunch of programs and you have external hard disk, it is better to allocate more memory.
8.Preparatory work was completed, but before starting the virtual machine you need to go to the settings section.
9.First go to settings, system, remove the option diskette, so as to load the operating system will disk or image.
10.It is advisable to include acceleration, especially if you are planning to install the 64 bit eight.
11.In the display settings, turn on both types of acceleration.
12.In the section "Media" you can specify where to boot the OS. If it's a drive, select live CD/DVD.
13.A window opens so you can specify the path to the downloaded Windows image.
14.Verify that the selected image was attached in the media.
15.Don't forget to go to network settings and enable there network adapter at the same time, by selecting the proper connection type.
16.In the settings USB is also required to carry out a few simple actions. Install filters to one of the connected device displayed in the host operating system and other virtual machine (also for correct operation of all USB plug-in created plugin VirtualBox 4.2.16 Oracle VM VirtualBox Extension Pack, it can also be downloaded from the official website).
17.Another important parameter in the General section of the folder. Create a folder for sharing in any directory. In the settings you will need to click on the folder with plus sign, then choose it and be sure to tick the box for auto-connect.
18.After clicking OK in the settings window, you will return to the VM, it can now start.

The installation of the virtual machine and its configuration ends. The idea is that after completing all the steps, you should open a window that will run the new OS.

What to do if you receive the error?
Nothing is perfect, and the use of complex technologies, mistakes are quite possible. I have, when you try to start the virtual machine, appeared this window.

To solve the problem is not difficult, but it will need to go into BIOS. It looks all different, I have a modern version, but the steps are no different, so with knowledge of the English language, you can easily fix the problem:

1.Go into the BIOS and go from there to "Advanced"section.
2.A window opens with a proposal to switch to advanced mode, click OK.
3.Now go to the tab "Advanced" where you have to select a configuration of CPU.
4.If you have Intel, you will need to enable a special option.
5.If an AMD processor, enable the option Secure Virtual Machines. Press F10 and save changes.
6.By doing this, when you try to start the virtual machine, opened the window where you began installing Windows.

Then you will understand, install OS as usual and begin to use it.

A virtual machine is really convenient, and perform the necessary actions once, you will be able at any moment to run them. Evaluate the opportunities for additional OSes, without installing it to the hard drive and awkward transitions.
