As we commented before, VirtualBox is an application that allows you to create virtual machines on your computer and run a different operating system and programs without partitioning your disk or installing a new one. After you install the software, you specify for the new machine the space on disk and amount of RAM memory you are going to destine for it. You have to be careful not to give too much RAM to the new machine since it will lower the performance of your native operating system. Virtual box automatically makes some presets for you, anyway.
After you create the new machine, you locate your mouse pointer in the open window of it and start it with the CD of your alternate operating system in the CD drive. After you install the OS you can continue adding programs and running them, watching the amount of RAM your are using. In case you don’t need the virtual machine anymore you simply eliminate it and all the disk space it was using, which was really just a special file with all the info, is free again. The amount of space on disk is not just reserved but used dynamically, though.
With this amazing software you can create virtual LANs and even export your virtual machine to be used on another computer running VirtualBox.
