You can open *.iso files, but what you want is probably a way to burn this to a cd. I'd recommend CDBurnerXp as a burning tool. <a href="http://cdburnerxp.se/">http://cdburnerxp.se/</a> It will turn your iso image into a bootable cd. All you have to do after this is to reboot your computer with this cd inserted. <div class="gmail_quote">On Mon, Jul 27, 2009 at 5:06 PM, Mark C.

It installs from the web. You then have a choice at bootup of whether you want to use Ubuntu or Windows. <a href="http://wubi-installer.org/" target="_blank">http://wubi-installer.org/</a> -- Mark C.
