After partition tool GParted is done with the partitioning, I looked at the details and the further details of each action by clicking on them.
To save it as a record, I took 2 screen snapshots too (using the Screenshot tool), and it is said to be stored on /root. So after that, I reboot to Win7 (or can reboot to Ubuntu 9.04).
At this point, where can the files be located, as /root was there when GParted was running with Debian. thanks.
