Gparted complains about lack of space to create a partition

Question

I just installed Ubuntu 17 and removed my Windows 10 entirely.

I didn't have important data so I chose to erase all my data.

Now I'm facing a problem in creating a partition. Gparted keeps telling me I only have 192MB free:

I've already seen this thread :) it's different. I explained above. — Ahmad Ayman, Aug 30 '17 at 23:02
Have you considered this answer in particular: https://askubuntu.com/a/237453/480481 Looks like your root partition has taken up the whole drive (except the minimal 192GB free space). — pomsky, Aug 31 '17 at 00:16
Yea i tried thia method particularly, and didn't work it's 192 MB not GB. That's why it's driving me crazy — Ahmad Ayman, Aug 31 '17 at 01:35
What's your question? What are you trying to achieve? You set up Ubuntu to use logical volumes instead of partitions which can certainly be managed and resized but not with GParted. — David Foerster, Sep 11 '17 at 10:04
You already have a partition created, and mounted. What are you trying to achieve? — Elder Geek, Sep 17 '17 at 22:24

You need to create/modify LVM volumes using the CLI, or you could install a GUI like system-config-lvm.

In terminal...

sudo apt-get update

sudo apt-get install system-config-lvm

Then type lvm into the Unity dashboard search box to start this app.

Do backups of important files before trying to modify LVM volumes/partitions.

See https://wiki.ubuntu.com/Lvm for basic help. You can also search https://help.ubuntu.com for "system-config-lvm" and find a lot more detailed help.
