Bug Description
I attempted to install "Ubuntu 15.10" and "Ubuntu GNOME 15.10" using usb-creator. I tried "Beta 2" and a fresh daily (2015/10/10), both 64-bit. I tried it on five different computers. The resulting USB stick booted correctly on all UEFI-based systems, but on non-UEFI systems SYSLINUX presents the error message "Boot Error".
If I create the stick using usb-creator and an "Ubuntu 15.04" 64-bit ISO, the resulting USB stick boots fine on both UEFI and non-UEFI systems.
I tried two different USB sticks, same results.
I ran usb-creator on two different computers, using three different versions of Ubuntu (Ubuntu 14.10, Ubuntu GNOME 15.04, Ubuntu GNOME 15.10, all 64-bit), same results.
I used "Universal USB Installer" from PenDriveLinux.com on a Windows XP machine to create the Ubuntu GNOME 15.10 daily (2015/10/10) bootable USB stick, and *that* stick boots correctly on both UEFI-based and non-UEFI systems.
So, to summarize: if I use usb-creator, with any Ubuntu 15.10 ISO, and attempt to boot on a non-UEFI system, it fails. If I change any of those variables it works.
One more detail. I have one computer with a sophisticated BIOS; it can boot a USB stick in UEFI-mode or non-UEFI mode. On that computer, the bootable USB stick worked when booted in UEFI-mode and failed in non-UEFI mode with the same "Boot Error" as everything else.
(To be explicit: the bootable USB stick was created by usb-creator, and contained Ubuntu GNOME 15.10 daily from 2015/10/10, 64-bit.)
