SEC: UNCLASSIFIED:-[newbie]Making a backup copy of Linux-Mandrake boot disk for version 6.5

[marco . mastrocinque]

Hi All,
             Have installed a linux-mandrake version 6.5 on my system. I use a
boot disk to install the system. Not sure how to make a backcopy? May seem very
obvious but not sure as I'm very new to linux.

Thanks Marco.
