I have been running Ubuntu 14.04 32 bit for a while but was told that my computer could run a 64 bit OS. So I downloaded Ubuntu 14.04 64 bit for desktop iso and made a bootable usb using Ubuntu's startup disk creator. I plugged it into the computer and tried to boot from the usb. When it tried to boot, this message showed up;
Missing parameter in configuration file. Keyword: path
After that these lines showed up and duplicated every few seconds;
gfxboot.c32: not a COM32R image
Does this mean that I cannot run 64 bit Ubuntu? Also, I am using a Dell Inspiron 1525.
