Zorin OS 9-Booting from liveUSB error

I am attempting to install the Ubuntu-based Zorin OS 9 via liveUSB. I have done a number of installs of Ubuntu based OS's but have run into a problem with this one.

I have created a liveUSB within my installation of Zorin OS 9 Core using three different applications...UNetBootin, the out-of-the-box Startup Disk Creator, and MintStick from the Linux Mint repositories. Now, you may ask how did I get it installed on the machine I'm using to begin with?!? I created a DVD using Brasero. The machine I'm going to install it on has no optical drive hence the need for a liveUSB.

When booting from the UNetbootin and Startup Disk Creator I get the following error:

BusyBox v1.21.1 (Ubuntu 1:1.21.0-1ubuntu) built-in shell (ash)
Enter 'help' for a list of built-in commands.
(initramfs) stdin: Not a typewriter
mount: mounting /dev/loop0 on //filesystem.squashfs failed: No such device
Can not mount /dev/loop0(cdrom/casper/filesystem.squashfs on //filesystem.squashfs

When using a liveUSB made with MintStick the machine starts, I hit F9 for the boot menu, arrow down to select the USB drive, hit enter and the machine boots directly into the Ubuntu installation.

Extra specifics - both the machine using to create the live media and the target machine do not have any duel booting. One machine is an ASUS (target machine) and the other is a HP. When I installed Ubuntu 14.04 on the target machine the live media was created using MintStick installed within Xubuntu 14.10 and no issues.
