I've been trying to boot into a bootable USB I created using Rufus with "GPT scheme for UEFI" and Fat32(I've tried NTFS too) partition from Ubuntu 16.04 iso file. When I plug in my USB, it shows up with a Windows icon, pressing enter makes the screen black with just the windows logo in the middle and pressing any key takes back to Clover. Pressing space while that partition is highlighted takes to a new menu screen which only shows two options 1. Boot Windows 2. Return. Pressing boot windows also just shows the logo. Am I doing something wrong?
