In the end I gave up with Macrium Reflect. I hosed the disk, set BIOS to Legacy, and did a clean install of Win 10, fully updated. Runs ok no probs.
I have 5 E6410 machines here with latest A17 BIOS and fully updated to Win10 ver 1803. Four of the machines are set up in Legacy boot mode, and they run fine. However the fifth machine has been set up in UEFI boot mode and has run Win 10 fine up to the 1803 update. Since then, the machine fails to shutdown completely with the power button remaining illuminated. If I press the button for a few seconds, the machine fully shuts down. Is there a fix for this?
