    Laptop unable to boot from new SSD


    I need help transferring my desktop SSD to a new SSD that's going into a new laptop (Dell 7420).

    I used macrium relfect to clone the my desktop contents onto the new SSD that was then put into the laptop but it keeps saying no bootable device found (even though the SSD can be seen in bios as it recognises the brand and size).

    I've tried changing the SSD from MBR to GPT but this didn't help.

    This laptop BIOS does not support legacy boot, only UEFI. I've also tried changing from RAID to AHCI/NVME and this didn't help either.

    I really want to avoid doing a fresh install even though it seems likely but at this point I want to at least try to get this working since I've spent so long on it. Any ideas on what I can do or try next? The laptop m2 nvme slot definitely works because the current 512gb 2230 in there works with no issues so I don't know why my new one isn't being recognised.

    is the new one an nvme disk?

    was the source for the clone mbr?

    how did you do the conversion ?

    there have been numerous reports of macrium clones failing to boot, it can sometimes be fixed by running macriums "fix boot problems" or by running bcdboot command. I suggest diskgenius for os migration, it is very reliable.

    Since you somehow converted the cloned disk to gpt, it is not clear if there is now an esp partition on the cloned disk.

    That's right, it's a new nvme disk.

    The source was also MBR.

    I used easeUS to convert to GPT and back again to MDR. It's now currently MBR.

    I've attached a screenshot showing the disk and its partitioins. (I did try bcdedit but it can't find the boot file on this disk)

    The new nvme is disk 2.

    I would shrink D from the left by 300mb.

    delete the 50mb on disk2 so there is now 350mb unallocated space

    convert disk2 to gpt non destructively using a 3rd party partitioner.

    create esp partition and msr in the 350mb unallocated space.

    300mb esp partition and 50mb msr partition will be fine.
    The msr partition doesn't seem to be absolutely necessary but ms recommends it.


    populate the newly created esp with the necessary boot files using bcdboot command.

    Thanks for the help so far.

    I've followed the steps and managed to create the esp and msr partitions.

    But I'm now stuck on populating the esp, using bcdboot C:\Windows /s W: /f all just gives me an error. I've tried other variations and it still doesn't work.

    C:\Windows /s W: /f all
    the first bit is the windows partition

    In your case you need the cloned windows partition, not your currently booted C partition. The cloned partition was D: in your earlier screenshot.

    the bit after the /s switch is the destination for the boot files. It can be either the drive letter of the esp partition, or the device path.

    there is no W: in your second screenshot, so what were you pointing at?
