liveusb-creator and "cp - non-destructive method"

[Giulio E.]

Hi guys.

I've been trying to create a USB stick with the GUI 'liveusb
---reset-mbr'. The ISO is "Fedora-Live-KDE-x86_64-22_Beta-TC6.iso" and
the USB stick is a new one (I'm almost sure it is sane).

There are two final results:
1) The 'dd method' seems to work fine and creates a bootable device
2) The 'cp method' seems to work fine, but then, after booting the
stick, I receive the message 'Missing Operative System'

Is that an intended behavior? Have you ever experienced this issue?

By the way, there is a similar bug report:
https://bugzilla.redhat.com/show_bug.cgi?id=1175514

But I'm sure I didn't set up an overlay.

Kind regards.

Well, after a hour or so of testing I found that it probably was
something related to the way I formatted the USB stick's partition.

I checked with KDE's and Mate's ISO: the 'cp' method worked and created
bootable devices. I also did some tests with (and without) custom labels
nor boot's flag.

I was not able to reproduce the issue at all. The tool behaved as it
should; so for me the case "QA:Testcase_USB_stick_Live LiveUSB-creator"
finally passes.

The non-destructive luc method can indeed have varying results 
depending on the existing partition table and filesystems on the 
stick, yes.
