swapon: /dev/hda5: Device or resource busy (etc...) ???!!!!

Hi,
that's my first attempt with linux so bear with me.
I am trying to install on an old Pentium I have at home but I have got this error from KNX2HD:

------------------start screen dump ------------------
root@1[knoppix]# knx2hd

----------end screen dump ---------------------

I know someone in this forusm suggests not to use Knoppix for HD installation but I am using the Live CD version on my company laptop too.
Can somebody help me ?

Thanks
