copying Ubuntu partition
 

how can copy Ubuntu partition completely to another empty partition on another hard disk so that be executable like before?

Hi!
You can use "dd" utility for making a full copy of you disk partition
(e.g. "dd if=/dev/hda1 of=/dev/hdb1 bs=1m" where /dev/hda1 is your ubuntu partition and /dev/hdb1 is you empty partition).
Notice that /dev/hdb1 must be unmounted and has same size as /dev/hda1; You can create that partition in cfdisk utility;
dd make copy byte-by-byte, so if original partition is bootable - copy partitional state bootable too;

it's all in general terms, for more information read dd docs (man dd)

best regards

P.S. sorry, I did not pay attention to the date of post. but answer can be useful to someone else

Greetings to all!

To add to what LiteCFD wrote, the easiest to use should probably be Clonezilla: http://clonezilla.org
It uses a liveCD or live USB. And AFAIK, it's not possible to use it directly from Ubuntu.
