I am using Ubuntu 12.10 which is on a dual boot with Windows 7. I initially had 30 GB for Ubuntu ,but I decided I need more , now I booted Ubuntu from its Live CD ,used GParted , shrunk Windows partition by 50 GB ,so I got 50GB-unallocated space. Now I want to merge that with Ubuntu's partition (extended) . But I keep getting an "overlapping partition" error , and I am not able too identify where the overlapping is happening. Can anyone please help me out here ? /dev/sda4 is where my Ubuntu's 30GB extended partition is (which contains /dev/sda5 and /dev/sda6) and /dev/sda3 is my Windows 7's partition. I have 50GB of Unallocated space between /dev/sda3 and /dev/sda4 ubuntu@ubuntu:~$ sudo fdisk -l -u

You might have encountered the following bug:

Bug 686668 - Growing logical partition overlaps end of extended partition

This problem was fixed in GParted version 0.14.1.

To use the latest version of GParted (currently 0.16.1), you might try booting your computer from media containing GParted Live.
