    Which tool to recover the EFI partition? Booted into Rescue Disk


    My EFI is blown away. The rest of the disk is good.
    I have a thread going in 'general' but this is also relevant as it's kind of an upgrade you might say.

    I am overwhelmed by options.

    There is diskpart, Macrium Reflect on the rescue disk, Bootrec.exe tool... what else.
    I am getting nervous running diskpart and rebuilding the EFI with it.

    :)

    Disk Boot Failure, Attempting to restore EFI partition


    I would highly recommend you do as @dalchina suggested and boot the computer from Kyhi's Recovery Tools and see what the diagnostic tools on his recovery tools can do to fix the drive - you need to look specifically at partition recovery programs. From the screenshots the only partition you have on the drive is the 450MB Windows 10 recovery partition at the very end of the drive. You need to do more than create an EFI partition or "Fix Windows boot problems", you need to recover the Windows partition, if possible.

    Disk Boot Failure, Attempting to restore EFI partition


    So I've attempted the steps @dalchina suggested but it seems that Macrium Reflect can no longer "see" my Windows partition on my SSD drive. I am able to run Power Disk Recovery (should I be using something different?) and find what looks to be my Windows partition but I'm not sure if this is the best way to go about restoring my original boot partition - if indeed this is even advisable.

    Is there a better way to rescue my old Win10 boot partition?

    I'm also considering RMA'ing my SSD drive but would like to run a diagnostic on the drive itself first...

    Is there a utility on Kyhi's Recovery Disk (HDDScan?) that will do this?

    Can I delete one EFI partition?


    You should be able to delete that middle EFI system partition. This is what I would do. Make a bootable USB flash drive or DVD of Kyhi's recover tools:
    Windows 10 Recovery Tools - Bootable Rescue Disk

    Boot the computer from it (to make sure it works, for one reason). Use Macrium Reflect Free to make an image backup of both the EFI System partitions. You can use AEOMI partition assistant on the same flash drive/DVD to delete the middle EFI system partition, then reboot the computer from the HDD/SSD. If it has a problem, boot back to Kyhi's recovery tools and restore the EFI system partition you deleted from the backup image and then attempt to delete the other EFI system partition from the HDD/SSD.
