Struggling to Make My Virtual Machine Work

I've been up and down the comments section here and I can't seem to find advice on this, so I'm hoping you can help.

I get to step 5.2 (right after ejecting the virtual CD) and...nothing happens. I get the screen as pictured, and when the startup options timer runs out, that's it. It just hangs there on a blank grey screen. Maybe I made an error on a previous step? I know it says,

When the installation finishes, Mac OS X will crash into a black screen with white text.

but my two-minute memory has already forgotten whether that happened or if it simply said "installation complete" and I went from there.

Any ideas? (Should I delete the whole thing and try again, maybe?)
