I've read some other threads with the same issue, not being able to solve my problem.
When I try to install Ubuntu with a USB, it does not recognize the OS I have already installed (Windows 8). I want a dual-boot system, I don't want to replace the one I already have.
It's a new notebook where I'm installing it into.
I've read this https://help.ubuntu.com/community/UEFI but it does not state this problem I'm having. I don't know if I have to make a new partition (or how), or what else to do. I have also read this Ubuntu is not detecting previous OS partitions but I don't understand what to do once I type what it says.
I would install it buy using Wubi but it fails on the middle of the instalation.
Here's the screen from GParted:
