Persistent live USB Ubuntu 14 not working

Question

Used Fedora Live USB creator 3.12 to create a live USB of Ubuntu 14 (latest 64 bit build)

I can successfully boot the USB on my Surface Pro 3 but I cannot get the persistence to work. It is not an option in the Grub menu either. I am using a 32GB drive and I did enable a 4gb partition for persistence.

UNetbootin is a native Ubuntu app and it is also in the Fedora repos. — karel, Dec 03 '14 at 15:48
as said by @karel unetbootin gives you option for persistent data storage on live USB — Alex Jones, Dec 03 '14 at 15:54
Could we please stop recommending UNetbootin for UEFI and Windows 8 machines? I have nothing personal against the tool itself, there have just been too many users booting their new machines in legacy mode and wrecking their existing installations. — LiveWireBT, Dec 03 '14 at 18:14

Sounds like bug LP #1159016. Persistence not working on UEFI machines. You can fix this problem by editing the /EFI/BOOT/grub.cfg file and adding the word persistent to the lines starting with linux.

That sounds reasonable, given that the Fedora Live USB creator doesn't do modifications to the layout, which I'm not sure of. For UEFI the easiest way would be to just copy the files contained in the ISO to USB, then modifying said grub.cfg to add persistence should work http://askubuntu.com/q/395879/40581 – LiveWireBT Dec 03 '14 at 18:32
I don't see /EFI/ubuntu at all. Just /EFI/BOOT – user354383 Dec 03 '14 at 19:13
I used unetbootin, but had the same issue in Wily. On a live Wily USB, the file is in /cdrom/boot/grub/grub.cfg. It was mounted readonly, so I had to remount before I edited, using mount -o rw,remount /cdrom. – transistor1 Mar 11 '16 at 01:17
