I have recently built my own PC and I want to use Ubuntu as my OS, but when I try to boot Ubuntu up using my USB I get an error saying:

no default UI configuration directive found

I have tried to rename the OS Linux files, but that did not appear to work. (But I may have been doing it completely wrong.)

I'm running an AMD machine if that helps.

Here is a thread that might help. In addition to renaming the files, it mentions that formatting the USB key as FAT16, not as FAT32, might help. Some people complained that using Pendrivelinux installer caused some trouble.

Where does it say how to format as FAT16? – user134791 Feb 23 '13 at 5:47
