    MacriumReflect8 Cloned system drive to an SSD won't boot W10Pro


    I created a clone of an M.2 PCIe NVMe 512GB SSD (boot drive C ) containing a Windows 10 Pro OS on my ASUS Laptop to a WD_Black M.2 PCIe NVME 1T SSD in an enclosure attached by a new USB cable to my Laptop using Macrium Reflect 8. All indications from MR showed no problem and a successful clone. I had formatted the drive from its RAW state to a standard partition covering the entire capacity of the new drive prior to attempting the clone. Using the BIOS boot loader I instructed the Laptop to boot from the new drive in the enclosure. It failed to start. There was nothing wrong with the old drive or the windows installation. I am using the Laptop and Windows 10 Pro, version 21H2 Build # 19044.1387 at this very moment to write this note. Has anyone got a clue as to why I cannot boot from the new cloned drive or if there is any way I can cause it to work. Thanks.

    Did you attach the newly cloned disk internally?

    You stated that you created 1 single partition covering the entire new SSD. How many partitions did you clone to it? If you have 1 single partition, it is likely missing the EFI System Partition the computer boots from.

    Since I can't see any way to post a reply to each user who commented on my post:

    Here goes;

    to SIW2: answer is NO. It was to an SSD attached to the Laptop by a USB cable and special PCIe Caddy or External case.

    to Navy LCDR: I cloned my entire 512 GB C PCIe SSD drive, which is also on my Laptop. I formatted my larger 1TB PCIe SSD as one large partition to receive the cloned Windows 10 OS.
    Thanks to both repliers. All help welcome! Any further suggestions most welcome.

    That really doesn't make any sense. On your original disk, there should be several partitions to clone, not just one. So how did you clone the multiple partitions on the original drive to the single partition you created on the SSD?

    Back to NAVYLCDR:

    So you can see what happened with the MacriumReflect cloning I attach an image of the Disk Management data respecting the partitioning of both the source drive and the destination drive. Something appears to be wrong with the clone. It does show a properly sized EFI partition and a a properly sized Recovery partition, but the OS partition is missing salient features. Why this happened, I have no clue. This may explain why it won't boot.

    From the screenshot above, open a Command Prompt with Admin privileges ("run as administrator"), and run:

    Code:
    diskpart
    select disk 2
    list part
    select part # <-replace # with the actual number of the 100 MB EFI System Partition, going to be 1 or 2
    assign letter=s
    exit
    bcdboot E:\Windows /s S: /f UEFI
    diskpart
    select vol s
    remove
    exit
    exit
    Then see if you can boot from it.
