A couple of days ago, I downloaded VMware Player. I have installed some Virtual Machines, including Linux and ReactOS 0.2.9. This is the way to try out ReactOS. There's no need to burn a CD, then reboot the PC. Just launch the Player, then choose the VMX file (or just double-click on the VMX file) amd you've booted to that OS in a virtual machine on your PC. The machine is only able to access those devices that you want it to.
Run virtual machines created by VMware Workstation, GSX Server or ESX Server. VMware Player also supports Microsoft virtual machines and Symantec LiveState Recovery disk formats.Easily and safely evaluate pre-built application environments, beta software, or other software that is distributed in virtual machines, without any installation or configuration hassles. Share a virtual machine with a colleague or friend."
