I can't figure out how to get my computer to boot the live DVD. It won't just boot the DVD on restart. I've gone into the bios and was confused even though I've altered boot priorities on other computers. I found the advanced startup in Win8 and selected to restart from DVD, but it just restarted windows.

I'm not planning to keep ubuntu, but I would be willing to just install it, except that I need to install 32 bit. That is what I've downloaded, but the installer keeps downloading 64bit. If I run the installer while disconnected to the internet, it doesn't work.
