Mega(1280) not showing up in Tools > Serial Port

I am having trouble programming my Arduino MEGA(1280). I just used my UNO to put the bootloader on it using http://www.gammon.com.au/forum/?id=11635. I didn’t receive any errors, and it looks like it was verified.

I then tried plugging the MEGA into my USB port, but it didn’t show up under the Arduino 1.0.5 IDE on Windows 7. I went into Device Manager, and the board is showing up as “FT232R USB UART”. Does anyone know how to make it show up in the IDE to upload sketches?
