10.4 is not supported as Guest OS. 10.5 and 10.6 are, but only the server releases. 10.7, codename Lion, does not work in VB, even though the EULA permits it. Speaking of EULA, you're trying to run the desktop version, else you wouldn't say you got errors with your install disc (btw, I can't see your tiff image, create jpg or png instead). With that said, read this: Important notice regarding Mac OS X as Guest
Since you don't specify that it's about Server, I will lock this thread.
