Resizing NTFS Partition using gparted and chkdsk

Today I installed Ubuntu 12.04 on a Laptop which had Windows XP and Ubuntu 10.04 in dual boot and large extended NTFS partition on E:/ drive. First I tried to resize the NTFS partition using gparted of Ubuntu 10.04 but it failed and also made the NTFS partition unmountable on Ubuntu. I corrected the partition using testdisk and it became mountable. Then I decided to try gparted on Ubuntu 12.04 and successfully resize the partition as follows:
I inserted the usb Startup disk into usb port of the Laptop and booted into Ubuntu 12.04. Clicked on top left icon called Dash Home and searched for gparted and clicked on the gparted icon. I right clicked on the NTFS partition and selected check. As expected the gparted produced following error:
GParted 0.11.0 --enable-libparted-dmraid
Libparted 2.3

ERROR: NTFS is inconsistent. Run chkdsk /f on Windows then reboot it TWICE!
The usage of the /f parameter is very IMPORTANT! No modification was
and will be made to NTFS by this software until it gets repaired.


Then I rebooted into Windows XP and opened command prompt

>chkdsk E: /f

Then I  rebooted twice in Windows XP.

Once again I booted into Ubuntu 12.04 using usb startup disk and started gparted, right clicked on the partition and selected check. This time gparted reported as follows:
GParted 0.11.0 --enable-libparted-dmraid

Finally I could resize the NTFS partition and make a new ext4 partition to install Ubuntu 12.04.
