When using GParted to resize Windows 10/8/7 system partition, only to find out Gpated unable to resize NTFS partition. You may find that the Move/Resize option is grayed out or some error messages.
This may occur when the kernel that has support for mounting NTFS file system is absent. You may try to install “ntfsprogs/ntfs-3g” to fix this.
Bad sectors on the partition to be resized may also cause this problem. You can boot into Windows to run chkdsk command. It is always recommended to do a defragment before making changes to partitions.
If GParted cannot resize NTFS partition still, try the following fix command:
sudo apt-get install ntfsprogs
After these steps, you should be able to resize NTFS partition.
Apparently, it is not the best tools for managing partitions formatted with NTFS file system. After all, GParted is a linux-based free partition tool. If you can boot into Windows, it is highly recommended to use Windows partition tools for NTFS partitions.
