Error creating High Sierra USB: "Couldn't detach OS X Base System"

[rcampillo1]

Hello all !!! ... I am getting the error:"Couldn't detach OS X Base System" when trying to create the
bootable USB !!! ...
I have tried with several USB memory sticks with the same result !!! ... Any Ideas ???
THKSM in advance !!!
Best regards,
Rafael
P.S. I am using the newest Unibeast v8.0 to creating the USB.
AAAhhh .... One more thing ... Actually I have my MacOS updated to
Sierra 10.12.6 version 16G1033 !!!! ... Could this be the reason ???

UPDATE !!!

After repeating the USB creation process and getting
The same error several times, I noticed by a casual
Fact that the USB was CORRECTLY build no matter
Of getting the error message !!!

The bootable USB worked perfectly !!!

Were you able to Install HS successfully? The reason I'm asking is that I'm also getting the same error, no matter how many times I format/reformat the pen drive with GPT partition scheme.

Hello,
Attached are the unibeast and install logs wherein I tried thrice formatting/reformatting the pen drive to get the same error as the thread name. Please see if anything can be found using these.

Thanks.
