system installation - "Boot Error" on live-usb flash drive with 15.10

I'm trying to install Ubuntu 15.10 32bits on a Samsung NP-N150-JP05FR, with a live usb created with usb-creator-gtk (from ubuntu 15.10, as superuser) on a FAT32 usb flash drive and get this error :

SYSLINUX 6.03 EDD 20150813 Copyright (C) 1994-2012 H. Peter Anvin et al
Boot Error

Any key pressed make that message repeat.

I often install ubuntu with live usb, using either usb-creator-gtk or UNetbootin. I actually already installed ubuntu (14.04) on that computer a few months ago. I can't figure out the issue.

Already tried :

• different USB flash drives


• checking .iso integrity


• renaming isolinux files to syslinux



• checking for USB Mass Storage Emulation type option in Bios (no such)


• UNetbootin instead of usb-creator-gtk


• removing "ui" from syslinux.cfg

According to the release notes at https://wiki.ubuntu.com/WilyWerewolf/ReleaseNotes you can't use usb-creator from lower version of Ubuntu ( including 15.04) to make live-usb of Ubuntu 15.10

Due to changes in syslinux, it is not currently possible to use
usb-creator from 14.04 and earlier releases to write USB images for

15.04 or later; we believe that it is also not possible to use usb-creator from a 15.04 or later system to write USB images for
earlier releases. For now the workaround is to use a matching release
of Ubuntu to write the images, but we intend to issue updates soon to
work around this incompatibility

You may still make it from 15.10 or from Windows(universal-usb-installer for example)

I tested usb-creator-gtk from ubuntu 15.10 in my virtualbox, it crashed at the end of the process! So we have to say NO to usb-creator-gtk! Tested with unetbootin 608-1 installed through USC, writing to usb succeeded but usb is not bootable!

However, I found away that worked perfectly inside ubuntu, even with older ubuntu version.

1. Right click your ubuntu-15.10-desktop-amd64.iso > Open with Disk Image writer


2. Choose your usb drive and click Start Restoring... and follow the instruction.

That usb is bootable without any error. After installing ubuntu, you will need to format that usb with gparted if you want to store data on that usb again.
