Just add it before rhgb right?

Tried and after I hit F10 to boot, it says "Booting a command list" with a steady cursor, and then after a period of time, just a black screen.

I also tried removing "silent" to see if I could get any output, but nothing. I don't want to turn this into an unrelated support thread on you Matthew, so let me know if I need to take this elsewhere.
