I am attempting to install Lubuntu using Wubi installer, however I am not succeeding. The installation process on Windows goes fine, then Wubi demands reboot, I do so and choose Lubuntu from the Windows boot menu. Then it loads and at some point, it always fails, reporting an installation error due to issue with media, implying that media is dirty is or damaged. This is happening both with Lubuntu and Xubuntu. Oddly, I was able to install Ubuntu, but this is an old desktop and Ubuntu doesn't run smoothly, so I need to look for the lighter alternatives LXDE and Xfce.
Any ideas on why this is happening and how to fix it?
