If you make a New topic you are noticed among unanswered posts and the chances are you get an answer much faster
And it happened to be in one of "my threads", somewhere else it might have been unnoticed
This problem is unfortunately well known to us
There may be two culprits
Your video - use safe graphics mode
The chipset
To fix that (this is taken fromthe Ubuntu forum)
Test break=button this "nonsense command" let some people get into a real command line environment - not the hopeless busy boxyou are getting this error (and you have a SATA harddrive); this is the fix:
At the LiveCD initial boot screen:
o Select F6 for more options
o Add the following option to the beginning of the options list:
break=top
o Press enter to start booting
Ubuntu will start booting, but kick you out to a command prompt; at the prompt type these two commands:
modprobe piix
exit
You will now boot into the LiveCD normally.
