I'm quite new to this, but the instructions seem pretty simple to follow. At boot type: config=live.plist

then at root type: bootlive; exit

I left the RAMDisk blank for this first attempt, just to make sure it worked.

So I pressed Enter and waited a moment, then it gave me this error:

Something about not being able to find a network or local drive. Any ideas? I tried it on 3 computers and got the same result every time.
