If you have Desktop or Laptop having Vista preinstalled and you are planning to try out Windows 7 operating system then VPC (Virtual PC)
is the best way to install. It’s completely safe and easy to install an
operating system in VPC without creating a new partition to install new
one.
Though you can dual boot Windows 7 with Vista
(Vista installed first), it’s a good idea to use Virtual PC to install
Windows 7 inside the already installed Vista. For those who don’t know, Microsoft Virtual PC
let’s you run multiple operating systems at the same time on the same
physical system. You can switch between two operating systems within
seconds.
In this tutorial we will show you how to install Windows 7 inside Windows Vista using Microsoft Virtual PC.Requirements:* Windows 7 DVD* Microsoft Virtual PC (free)Procedure:1. Download and install Virtual PC from here.2. Run the Virtual PC software. To do this, type Virtual PC in Vista Start menu search box and hit enter.3. Click on “New” option and click “Next” to continue.4. Select “Create a virtual machine” option from the available three options. I prefer this option as this lets you customize as you like. Click “Next”.5. Here, type a name for the new virtual machine. The file is automatically saved to the My Virtual Machines folder. To save it to a different location, use the “Browse” button.6. Select the operating system that you would like to install using Virtual PC from the drop down box. In this tutorial we choose “Other” since Windows 7 option is not available in VPC as of now . After selecting the operating system, click “Next”.7. If you have more than 1GB of RAM in your system, select “Adjusting the RAM” else select “Using the recommended RAM”. If you have chosen “Adjusting the RAM” then, select the amount of RAM you would like to allocate to run Virtual machine (Windows 7) and click “Next”. (By default, it will use 662 MB of RAM, if you like to keep as it is, blindly click “Next”).8. In the next screen, select “A new virtual hard disk” and once again “click” button.9. In this step, browse the location where you want to create a virtual hard disk and specify a name for the virtual hard drive. Also don’t forget to specify the size of the Virtual Hard Drive. I prefer at least 16GB (Recommended by Microsoft).10. Click finish button.11. This will open a small window called “Virtual PC Console”. Click on “Start” button to start the actual process.12.
