Thank you again I am enjoying it.
I was actually surprised to find a free tool to migrate Windows from an MBR HDD to a GPT SSD drive.
For other users of the Asrock Z77 Pro4 Mainboard, in the BIOS, CSM must remain enabled, or the NVME drive is not detected. In my case I used the PCIE Gen3 16x slot although NVME only runs at PCIE 4x. The 16x slot was empty after my graphics card packed up. There is also a Gen 2 4x slot, which I could use for the NVME adaptor should I buy a new graphics card. Lets see how long the MB lasts.
