Do You Want to try a different Operating System to increase the experience, but obviously you hate to Format your Computer and again Installing the softwares, drivers, games to make it usable again. Then, let me tell you, there is a solution, called the Virtual Box. Virtual Box is an open source software developed by Oracle. After installing Virtual Box to your Computer, You only need iso image of the Operating System Installation Disk to begin. Virtual Box creates a virtual Hard Drive on your computer. It uses this virtual Hard Drive as the Hard Disk of the OS you want to install. Apart from this, you need to allot some resources to your OS, like RAM. This alloted RAM will be the RAM of the istalled OS.
I like Virtual Box as it allows you to communicate between the Virtual Machine and the Host Machine through a share folder. You can create a share folder on your computer. This folder will be treated as the network drive by Virtual Box.
I am currently using Windows 7 Host Machine and a Fedora Virtual Machine.
Here is a screenshot.
I will recommend you to use Virtual Box only when you have got more on the Hardware. If your RAM is good, it is a good option for you.
You can Download this OpenSource Software from here.
If you face any problem in using this, you can always ask me.
