I tried downloading the 32 bit version of Ubuntu 13.04, and when it finished, I used the universal USB installer tool, provided on the ubuntu website. That was all successful, but when I tried to boot it, the GUI was completely messed up. It loaded the system itself, but once it went into the desktop with the dialog prompting for a language for installation, the screen went whacko. Every other Horizontal line of pixels was messed up, and it had columns (kind of) that repeated what the screen should look like, but only a small region of it.
My Processor is AMD 64 bit, so I tried again with the 64 bit version of Ubuntu, but the exact same thing happened. (By the way, I have slow internet, so each download took about 4-5 hours, along with several failed downloads.) I tried the same thing using a different usb mounting software, but the same GUI issue happened. Each time I retried, I completely wiped and re-formatted the USB disk. Nothing is working. What should I do? Should I download the Windows Installer? Use a CD? Please help! Any feedback is appreciated.
