I successfully followed instructions in to make a bootable usb drive for ubuntu12.04 using the command 'gksudo usb-creator-gtk' in a terminal window - there were no error messages and the final pop message said I can now use the USB drive to successfully boot a system into the latest Ubuntu 12.04

However, on a brand new samsung laptop (NP-300E5Z-A0PIN - a i5 core machine), I get the following message: SYSLINUX 3.63 Debian-2008-07-15 EBIOS Copyright (c)1994-2008 H Peter Anvin Unknown keyword in configuration file Boot:

It hangs there...

Am I missing out any steps... how do I proceed with the installation... Many thanks in advance

This also happened when I tried booting on a ACER aspire 4710 laptop that I run an older version of ubuntu (and on which I made this bootable USB drive) – Drake May 23 '12 at 18:01
Did you check the md5sum of the iso ? – bodhi.zazen May 23 '12 at 18:21

I found this site, hopefully this will help you. Click Here

Below is the solution from that site:

After creating a USB bootable version of Ubuntu from the Startup Disk Creator (or usb-creator-gtk) and attempting to boot, I was greeted by the error above. It might look a bit scary but it’s really easy to fix, just plug the USB flash drive into a computer (windows or linux, mac too probably but I haven’t tried that.)

Solution 1:

Open the the syslinux folder in the root of the flash drive.
Inside is a file called syslinux.cfg you’ll want to edit that.
Find the line “ui gfxboot bootlogo” and simply remove the “ui “.
Save and try booting again.

Below is how my syslinux.cfg file looks after editing:

# D-I config version 2.0
include menu.cfg
default vesamenu.c32
prompt 0
timeout 50
gfxboot bootlogo

Solution 2

Alternatively it looks as though there is another way of fixing this issue if there is no “ui” in the file, this is to do as followed (as pointed out in the comments below):

Type “help” and press enter
Hit Enter again

This should boot correctly and shouldn’t need to be done every time.

Thanks a lot.... it worked.... Guess the original distribution should have been fixed long back.... – Drake May 24 '12 at 2:52
@Drake If this answered your question, you may mark this answer as accepted – Mitch May 24 '12 at 6:29
Solution 2 worked perfectly! Thanks! – Fabio Gomes Jun 13 '15 at 17:14

The problem is that usb-creator depends on syslinux-legacy 3.63, and uses it to write boot up informations into USB, while the parameters "ui" can only be accepted by syslinux 4.05, which was installed on ubuntu 12.04.

A simple solution to solve everything is:

sudo mv /usr/bin/syslinux-legacy /usr/bin/syslinux-legacy.bak
sudo ln -s /usr/bin/syslinux /usr/bin/syslinux-legacy

And you can actually use syslinux 4.05 to write boot information into USB.

I used usb-creator many times, This problem wasn't there. It may not be the main cause. – Anwar Shah Sep 23 '12 at 4:07
