Do I need to reload Linux Lite again to set partition ?

[DLX]

I'm sure before I start to load LL I set two partition at 250gb and an 80gb for LL
The 250gb were left at NTFS I was going to change them later.

Now I'm looking to change size I can only see one drive with partition of 461gb.
I can't resize or unmount at the OS LL is using this drive.

The setting are grayed out I had this before I just had to unmount.

Using Gparted this should see the other NTFS partition right?
Is the easy and quickest way to format and reload LL again setting partition 80gb for LL

I have looked at youtube before I started this question.
