LiveCD Fails!?

[Husse]

Welcome to Mint
Your post is somewhat contradictory - on the one hand you say you boot successfully on the other that you end up in a "busy box" (which is a primitive terminal)
I suppose you mean that you manage to come as far as the "busy box" but no further....
This happens with some hardware and if the CD is not OK
Did you check the md5sum and burned as slow as possible?
If yes take a look at the troubleshooter
