Try what you did before, but leave out any display driver. You can correct the driver after the fact, so long as choosing no driver will give you some display to work with. (there is probably a slick command line way to fix this, but I am fairly new also and don't know how, but I have the hang of a couple distros.) As an alternative, try these options. This will use a vanilla kernel and will use PC EFI v9, which pretty much everyone should be shooting for. (if successful, it allows you to use Software Update without breaking your system!!!) I got it on mine. It's sweet!

God made man knowing his new creation would not live up to Gods' own standards, so God gave him a loophole, ignorance. Now man can exist in their imperfect state and God won't have to squish him. So, if I am ignorant at times, chill. God made me that way.
