Hello, in this thread http://www.experts-exchange.com/OS/Linux/Q_27375189.html
I found out that I lost my windows xp partition because mistakenly chosen as swap partition when installing ubuntu 10.04.
I used Gparted to turnoff the swap. Then used TestDrive to change the partition type back to ntfs. It is set as "primary bootable". see screenshot. I could see my windows files in testdrive. But after I reboot, Ubuntu does not see the partition and again gparted shows ubuntu is using it as swap.
How do I get out of this circle - I mean how do i set the partition as a ntfs partition that ubuntu no longer sees as a swap partition?
