I am trying to install ubuntu 9.10 in my pc. as instructed, I burned the iso file I took from ubuntu site into a cd and restarted my computer. after that, I was promted for the language I want to use. I chose english, then when offered four or five option, I chose Install Ubuntu. after this step, I wait for a while, and then I see a message saying I/O Error. when I view the content of the cd with windows, everything works just fine... so I guess my cd is not damaged. anyone have any idea what could be causing this. I also read that burning the iso file onto an 80-minute cd is preferable, so I complied with that too. any help is greatly appreciated.
