    Cloning OS disk, how to get boot records pointed to correct disk?


    I have 2 PC's, my daily driver and the new PC I'm building. I want to move the NVME SSD in my daily driver to the new build, but I want to keep my daily driver operational for a couple more weeks (after which I'll sell it), so I can leisurely set up the new build with all my apps and settings, and also test all the hardware on the new build.

    So to that end, I'd like to install a SATA SSD into the daily driver, clone the NVME (on which the Win 10 OS is installed) to the SATA SSD, then remove the NVME. I haven't done this in years, and I recall back then, in the MBR days, this operation can create boot issues because the cloned disk contains pointers to the source disk, which once removed, is no longer in the system. We used to use EasyBCD to get boot records pointed to the right disk. How is this done with GPT disks?

    I plan to use Macrium Reflect 8 Free to clone the disk. Does Reflect automatically handle this pointer issue when cloning?

    This video on cloning HDD with OS to a SSD using Macrium Reflect (and cloning all of the various Windows partitions) shows the last step as using Reflect's "Fix Windows boot problems" options pre-emptively. Youtube link is to the timestamp where this step is taken: UPDATE: Using Macrium Reflect Free to Clone Windows to a Bootable M.2 SSD - YouTube

    And one of the top comments to the video:
    Everyone. DO NOT SKIP THE LAST STEP. Just saved hours of time for me. I had skipped it and after a few days my pc stopped booting correctly. I proceeded to pull this video back up on my phone, and follow the final instructions with the rescue disk since I still had made it during the video, and bam, problem solved. THANK YOU access random! One of the best tutorials Iíve ever seen.

    Other comments say things worked fine without that last step and using the last step created boot problems. Confusing!
