Sorry, I don’t understand.
What does "Version 10.0.19042.685" have to do with this? That is the Windows build and is immaterial.
My comment related to the Intel ME (Management Engine), the last version for our board being 8.1.70.1590. Check in the BIOS for your version - if lower, update it using the contents of the IntelME.zip file by running from a DOS boot disk/USB BEFORE updating the BIOS.
Then, use the content of the P8Z68-V-GEN3-ASUS-9903.zip (not the zip itself) to update the BIOS from your USB via EZ Flash 2.
Please re-read the first post.
Again, your cloned Windows install MUST be converted to GPT (if not already done) or Windows will not boot.
