If you want to learn How to virtualize an operating system quickly and easily, I recommend you try VirtualBox. It is a free, open source and cross-platform program (it is available for Windows, Mac OS X and Linux) that allows you to virtualize all the main operating systems in a very simple way and without making the PC heavier. Of course, the speed of execution of virtual machines (as virtual machines created by virtualization programs are called) depends on the power of the PC in use and the amount of RAM available for software, but generally no major slowdowns.

If you want to download VirtualBox on your PC, connect to the program's website and click on the item related to the software version that best suits the operating system you use (in the case of Windows VirtualBox 4.2.6 for Windows x86 / amd64 hosts ).

Enter the name you want to assign to the virtual machine to be created in the appropriate text field and click the button siguiente to continue creating the virtual machine.

The next step is to first set the amount of RAM to be assigned to the virtual pc and then the size of your HDD.

VirtualBox will choose the optimal values ​​based on the operating system selected at the beginning. Finally click crear twice in a row and you will have completed the process of creating your virtual machine.

Once you have obtained the virtual PC in which you want run the operating system you want to test, you must go to the installation process of the latter, which must be done as if you were using a real PC. This means that you must first "power" your virtual machine system installation disc, and in this case the available options are two: physically insert diskette on the PC or use a Image File ISO saved in the hard disk of the PC.

In the first case, you must select the name of the virtual machine in the main VirtualBox window and click the button adjustments. Then go up Archivingclick on the icon CD (empty) it's on the left and click on the icon CD located on the right and then select the item Host reader from the menu that appears. In the second case, however, you must select the item Choose a virtual CD / DVD disc file (o Choose the album ) in the menu and select the ISO image related to the operating system you want to install on the virtual PC.
