Burn the ISO to cd (or run it from a virtual drive or from within a virtual machine.)

Here are the 3 ways to run VMWare Converter.

1.  Autostarting the CD from a drive (virtual or real) starts the 'no-install' hot cloning option.  The currently istalled OS, or a networked OS can be cloned this way.  An enterprise licence is required to 'no-install' hot clone the current OS, but it's possible to hot-clone a networked machine without one.

2.  You can explore the CD and install VMware Converter onto the current OS and then hot-clone it.

3.  You can boot up a machine from the CD (or virtual machine from ISO) and it boots into a WinPE environment and you can cold-clone the OS.

The third option is probably the easiest and cleanest.
