I wanted to dual boot Debian with my Ubuntu machine, but I cannot seem to create a partition using GParted. I go to "Create a Partition" but it's greyed out and I can't click "New".
I'm sorry if this is a stupid question, I'd just started using Linux and I've used Windows all my life.
Thank you!
EDIT: Going into a live usb didn't work.
sudo gparted
