http://www.linuxforums.org – I downloaded Ubuntu 9.10 and burned the image of the is to a cd using infrarecorder. After that I booted ubuntu and after i selected the language and try to install it, it gives me a message saying ERROR READING BOOT CD and it gives me an option to reboot. I tried rebooting it several times but the same error message keeps coming up. The disk is clean and I can read it on my laptop but not my desktop. Can anyone help me? (HowTos)
