What is the procedure, if any, for obtaining a proper installation of Ubuntu from the DVD installer on a USB drive?

I tried to follow the instructions on the DVD I produced from the ISO image. Working with OSX, when it came time to "install alongside other OS" that option was not presented to me.

After a lot of experiments I did manage to produce a set of partitions (why aren't these automatic or at least suggested?) that were acceptable and apparently got a good install on the USB drive.

However, upon attempting to boot with it, the "Option" hold did not produce an EFI boot possibility similar to what I get from putting the downloaded ISO onto a USB. I think that the Grub codes failed to get installed and recognized.

Any concrete help would be appreciated.

Bob

Take a look at my answer Here, it might help. –  Mitch Jul 2 '13 at 6:52
    
Mitch, I tried your pathway and it gave me some odd results. Instead of booting to the drive your app created, I got stuck in a dialogue with GRUB at the command line level. I don't think I should have to deal with GRUB just to boot up. –  Bob Terry Jul 4 '13 at 0:52

Well I have dome that with some success, but going back to my original question, it seems there is no guidance as to how to use the Ubuntu installer to create a system on a USB drive. The Ubuntu procedure lets me use the system from the USB, but it seems oddly limited. –  Bob Terry Jul 4 '13 at 15:54
