Ok here's what I did. I recreated the grub.cfg file and pasted the ubuntu configuration. Then I deleted both of the .lua files since I asume they're no longer required. After that I went into the isos directory, and renamed the ubuntu9.1 image to ubuntu.iso. When I booted off the USB flash drive, it gave me a menu. However when I pressed enter, since I only have one usb image, it just said something like, press a key to continue. Then it returned me back to the same menu. Am I missing anything else here? Do you think I need a menu.lst file? The post doesn't mention it though. or maybe I shouldn't rename the ubuntu file. Thanks for all the help!
