I'm interested in somehow getting a virtual computer program on my computer such as VMware or others. The thing that I've had noticed, however, is that they all require you to have the additional operating system that you want to run in order to boot from it. I'm looking for virtualization that simply uses a sort of "copy" your current computer(OS and all) without you having to have an additional OS cd, .iso, etc since i just want it to test software and am not looking to test (and do not want to buy) a different OS. Can any of VMware's software do this? If not, is there another program that can do what I described above without having an additional OS? Thanks in advance.
