I just hit the upgrade to get 11.10, and I really do not like it. I would like to simply re-install from scratch Natty Narwhal. I don't know where to download the ISO file from, because the Ubuntu website only shows the main download for 11.10 or 10.04. I already have the USB installer needed to put it on again, so if anyone could post a link to the download, that would be extremely helpful. Thanks.
