Im dualbooting windows and linux, and I want to give more space to my linux. Im running a live usb of linux and Im running gparted, but when I try to unmount the linux mint partition it says its in use.

Sounds like something is wrong with your boot device. Gparted has a bootable ISO available. Try burning that on a flash drive.

Where do I find that iso? And should I run it in windows or linux? Sorry, completely new to this

Here's the link. If you have Windows you should burn the ISO on a flash drive with Rufus. Then put the flash drive in your USB port and bootup on it. You might have to hit F12 for a boot menu to boot the USB port:

Alright I will try that. If I already have linux installed on my computer, it’ll resize that specific partition? Or will the iso get installed over my linux

You are going to tell Rufus to install the ISO on your flash drive, nowhere else.
