We are trying to upgrade a W8 system to W10 using the Media Creation tool, and it has failed several times and reverts back to W8.

According to the information in your log, you have THISLenovo Erazer X510 Type 90AC Model 90AC57327869 Desktop.

You should consider doing a clean install of Windows 10 64-bit in your desktop and getting a fresh start.
If you decide to go that route, make sure to back up any personal data you don't want to lose before you start.

thanks, Mike
