Started with Budgie. Then discovered Zorin which I am going to stick with.
Problem is that my system looks like this now…
I have tried to use Gparted and KDE partition manager, but it won’t let me delete unused and blank partition.
How do I make my Zorin Partition bigger and remove the partition that is now blank?
You can use GParted and then right click on your Zorin partition & select Resize. 
Vasileios,
Thank you for your reply.
This did not work.
I opened GParted, and when I right click, and get to the menu, it does not allow me to resize or move the partition.
I can create new partitions, but I cannot resize the Zorin partition.
Any other ideas, or suggestions?
Thanks
You have to do it while booted to a live USB. After booting to your USB drive, select GParted from the applications then you should be able to resize.
Wow this post really slipped through the cracks. As @GrillerMiller mentioned, you’ll need to do it from a LiveUSB where your Linux system is not active - as you can’t intervene on a partition while it’s being used.
