Using Virtual Machines is a great way to test software without making changes to your ‘main’ machine.
To create a virtual machine in Windows 7 without using 3rd party software you’ll need to download Microsoft’s Virtual PC. If you also want XP-mode, help yourself. Both are available here.
Once you’ve installed Windows Virtual PC you’ll probably want to create other VM’s running other OS’s.
To do that, do the following;
Navigate to (by default) your home folder and find the Virtual Machines folder, inside that folder on the toolbar click on Create Virtual Machine.
2. Name your VM and choose it’s location, click Next
Specify the amount of RAM you want the VM to use. I have 3GB RAM on my PC, so I’ve been using 1.5GB RAM in the VM, it works flawlessly. Uncheck the Networking box if you want the VM offline and hit Next.
Set your VHDD preference, undo disk gives you temporary storage so you can change the VM without changing the VHDD. Click on Create.
When your finished creating the VHDD you’ll need to install the OS, navigate to the VM folder again and select the newly created VM. Click on Settings in the toolbar.
Navigate to the DVD Drive tab and check the Open an ISO Image radio button if you’re installing the OS from an ISO, or Access a physical drive if you want to install from a real DVD.
Double click the same selection as before to power up the VM and boot from the ISO/DVD, proceed through the installation as normal.
