I am booting live booting Ubuntu from a USB flash drive. At the setup screen (this is the first boot), the screen is very pixelated rendering the software unusable. I am unable to get past the setup screen because of this. Here are some pictures:
The third picture has the same overlaid pixelated pattern as the fourth and fifth pictures.
I used Universal USB Installer to put the official Ubuntu 14.04 ISO onto my flash drive. After selecting the drive in the boot menu, the images tell it all. How would I be able to fix this problem and properly boot Ubuntu [Setting this up is very important to my development at this stage]?
Would downgrading to an earlier version have any effect?
Also I am a young web developer, new to Linux, so an explanation of why this may have happened is encouraged.
