@FrenchPress I am also not able to resize my current partition, i was once able to do. It shows an error like this. 
and here is my partition.
It looks like you have a "logical" partition, not "primary" partition.
I always avoid to use logical partition to avoid such complication.
I wonder if other volunteers on this forum could give you some advice. Last time when my daughter-in-law made this mistake, I ended up erasing everything and start over 
I know why this happened to me. Before i asked you, i inserted my Bootable drive of ubuntu and tried to install alongside Zorin. but after i rebooted, even after selecting ubuntu from boot manager, i instead ended up on opening zorin os again. after which i removed the partition of ubuntu. and this happened. All in all, linux is damn confusing for beginners or intermediate peeps
the fun part is after it said finished installing, i rebooted and it opened zorin os again 
i know a bit of coding but its of zero use over here
We all have to start from somewhere.
No one is expert till they decided to learn things by themselves.
Just like my fellow humans, I was not born with a computer skill.
I agree with you - if one do not want to learn anything, then Linux is a lousy OS.
The thing is that Linux is very vast, and hence it takes time to learn it.
Linux is just like an encyclopaedia.
Reading it though in an Alphabetical order is not a good way to learn it.
The best way to learn it is hand-on.
Try it and make a mistake and learn from it.
Have you ever heard of those people who learn how to swim without getting into water? It just would not work.
Oh yes, my dad says the same 
something tells me that your dad belongs to the same age group as myself
what's your age then
Well, you never ask the age to ladies 
Hahahaha 
Atleast age group 
Well, joke aside, I really have no idea how to salvage your "logical partition trapped" installation.
I wonder if @marko94 might have some idea.
I also wonder @Gekkouga managed to understand my instruction before @100WCharge "hijacked" the thread.

Not really , it was long ago when I worked with logical partition.
so basically , my suggestion, format whole disk to GPT, and than start from the zero 
GPT is also better for dual boot, your disk with 1 T etc

Please watch out the language you use on this forum.
We are striving for the Family/Kids safe environment here. Our tolerance level for crude/coarse language is very low.
If you do not feel comfortable with it, I suggest you to go other forums with much higher tolerance level.
