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:

enter image description here

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.

It is most likely a problem with your graphics card. Please post more info on the card you have. You will probably have to give the kernel the right boot options in the end, and that should fix it. –  noleti Aug 7 '14 at 4:56
It's an AMD Radeon HD 7700 Series graphics card. I am currently updating the driver, would this help? –  Jking Aug 7 '14 at 5:17
I am unable to do that for I cannot finish the setup and start applications. Also, updating the drivers in Windows did not do anything. Any suggestions? –  Jking Aug 7 '14 at 5:53
Take a look at the Ubuntu Installation/MinimalCD wiki for information about the Ubuntu text-only installer. –  karel Aug 7 '14 at 6:03
I have, and this was more of a graphical anomaly. Installation to the drive went fine. Should I try something different than UUI? –  Jking Aug 7 '14 at 6:52
