I’m trying to dual boot my Dell XPS 15 7590 running Windows 10 Pro with Ubuntu 18.04. After booting the live USB with try Ubuntu without installing or install Ubuntu I cannot actually install the OS. I’m using a 8 GB USB stick, but I cannot select the 128 GB partition I created before. I could only select a language and keyboard layout before this error message shows up: “You need at least 8.6 GB of free space to install Ubuntu. This computer only has 8.0 GB.”
Any idea what I could have done wrong?
