Why can't I join unallocated space with my NTFS partition in GParted?

Question

I can't resize my NTFS partition named My Folder to join the unallocated space for some reasons I can't get.

Answer 1

If you booted from the same hard disk that you are trying to resize partitions on, that would explain the problem. It is error-prone and often not even possible to modify partitions on the same disk you are using. You must instead run GParted from another disk.

Instead of running it from a system that is installed on that drive, boot into a live Ubuntu system. Boot from a USB flash drive that an Ubuntu ISO image has been written to, just as you would do if you were installing Ubuntu. But select "Try Ubuntu" instead of "Install Ubuntu" and then you can run GParted.

This was what happened to me. If you boot from same hard disk--I mean the hard disk where you want join or otherwise modify the partitions--It won't work. You have to use a live Ubuntu system instead.
