Hey, I want to install Ubuntu on a boot camp partition. I dowlnloaded and burned the 32bit file from http://www.ubuntu.com/getubuntu/download but my computer isn't seeing it as a bootable disk. It doesn't show up as an option to boot from. Additionally, I can load the partition with nothing on it and when I do it says "insert bootable disc press any key when ready" but it does not recognize my disc. Ideas? I am a total computer newb.
