I have followed the instructions as outlined : http://www.knoppix.net/wiki/Hd_Install_HowTo

From the boot: prompt I have typed 'sudo knoppix-installer' and receive the following message :
'Could not find kernal image : sudo'

I thought it may be a corrupt copy but I have downloaded it twice and I get the same message.
What am I doing wrong I'm I missing something simple here ! Both copies boot fine from the CD rom fine.

I have searched the forums etc. but I can not find an answer.

Much appreciated for all your help.
