I downloaded Ubuntu 12.04 to my desktop and burned to a CD using Infra Recorder and instructions on ubuntu website. Restarted PC to boot from CD receive black screen with "Loading bootlogo..." then nothing happens and I have to restart with windows.
The CD seems to be correct. Folders include .disk, boot, casper, dists, install, isolinux, pics, pool, preseed, autorun file, md5sum text file, readme.diskdefines file, wubi app.
