Startup Disk created on 16 GB Verbatim Store'n'Go V3 USB Drive cannot boot

[Steffen Sølling]

I created a Startup Disk using Startup Disk Creator on 64 bit Ubuntu 15.04 Desktop

The source image I used was a 64 bit Ubuntu 15.04 Desktop iso
The device I used was 16 GB Verbatim Store'n'Go V3 USB Drive

Startup Disk Creator did not report any errors.

However, the resulting startup disk is useless. I have tried using it on two different machines. They both report similar error messages. In both cases the boot proces ends with this message:

"(initramfs) Unable to find a medium containing a live file system"

I have submitted photo documentation from both machines in a zip file
