[ubuntu] partition table lost in Gparted

view story

http://ubuntuforums.org – I try to resize my hard disk partition to make room for Karmic Koala Beta using Live USB. While I am resizing, power down suddenly. The partition is corrupted and unable to boot. Then I search online, and found the testdisk program. It recover my partition and I am able to boot to my ubuntu. However, the partition is not showed up at Gparted. When i use fdisk -l, ubuntu can recognize all the partition. Now i am not able to install the new ubuntu, because i still have other thing in other partition. In the installation, the partition just show up like Gparted. One huge unformated partitiion.
