There have been reports such as this for years now, and I have not found a definitive answer.
From reading the few different 'solutions' some people found, it appears to be related to 'some' BIOS's having difficulty ..... most 'solutions' have been to use a different USB stick

Maurice, I think you long ago in this thread passed the pain/gain threshold.
No one here will consider your decision other than in that light, so no worries.

Some of us have more interest in the cause of the problem, than finding a solution (yes I mean me

) and this can colour our responses too, which may not be 'in the best interest' of the thread starter.
I do hope you have derived some benefit from the thread ...... even if it is more familiarity with the Live USB Creator utility, and the knowledge you CAN create a working USB stick, even if it might not work on that particular PC.
Take care ....... and back to having some fun!!!
