I followed the instructions on the ubuntu webpage. I tried two different downloads and I have tried 3 different CDs and 1 DVD. I tried ISO recorder and Windows default one. I changed my bios to boot from the CD drive. When I turn my computer on you can hear the disc drive spin like it is trying to read it but the screen just stays black with a white "_" flashing at the top. Then after a while it just boots to windows. Any ideas what's wrong? I am now downloading a copy of linux mint, not that I really want that but just to try and see if that will work.
