It seems the old problem of flushing is back.

When it is done however, it seems I can't actually boot from it. I want to re-install my laptop, using UEFI only (ideally with secure boot, but I don't know if it is possible), and full disk encryption, but I just can't seem to get a working bootable USB stick made. :-/ <div class="HOEnZb"><div class="h5"> On Thu, 2015-01-22 at 12:03 +0100, Daniel Holbach wrote: > Hello everybody, > > in the past few weeks I saw the discussion about what was the best way > to create Ubuntu USB sticks a couple of times.
