    system image backup, 807800c5 error


    hi,
    i have a problem with windows system image backup.
    my OEM windows 8.1 was installed on normal HDD with mbr partition config. so i bought an SDD make an image back up from my drive c. and then use windows DVD to recover(install) the image on new SDD.
    now after i upgrade to windows 10 i learned that i could change mbr to GPT and use EFi boot instead on using old legacy boot option.
    now after doing all these without reinstalling windows(caus i cannot go back to win 8.1 anymore)
    i decided to make a image back from windows 10 so i can restore to it in future.
    now the problem!
    the problem is every time windows tries to make an image, when it start to make an image from EFI partition it ran into this error :
    (the specified backup disk cannot be found) 0x807800c5
    really need help on this matter

    the error caused by another EFI system partition on the old hard disk which windows were installed on it.
    most people are (including myself) forget to remove this partition after mounting another hard disk or SSD and install the windows on the new one.
    the solution is to remove the EFI partition from old hard disk.
    1.cmd
    2.diskpart
    3.select disk X ( X== the number of your old HDD)
    3. list partition (find what is the number of your the partition labeled as system)
    4. select partiton X
    5. del partition override
    now you can make system image back up.
    you can extend one of your partitions using the newly created free spaced
    go to disk management select the partition you want to extend right click on it and select extend.

    I have the same problem with my backup failing, and I think this will solve my issue too, but I have one questions first. Here's my drive setup in Disk Management:

    I have two SSDs in the computer, a 240GB C: drive with the O/S (Disk 1), and a 480GB D: drive for scratch/storage space (Disk 0). So I don't know which, if any, EFI partitions I can safely delete. How can I find that out? I don't want to make it unbootable...

    Thanks for any help!

    If you just want to be able to restore, I would suggest using the Create Restore Point tool which work as a quick easy fix if anything goes wrong. If you still want a system image to boot off of or install (which is good to have), why don't you just use the tool Microsoft has made available for just that instead of creating one from your own system? Unless I've misunderstood the question.

    Hi KJax - thanks for the info. I think what I want is somewhere in between those two things... I want to take a snapshot of all my important files (which the Windows Backup program does automatically) and move it off to another drive for safety. This process gets part-way done then fails, like in the original post. I'd like to resolve my EFI question, remove the unneeded one, and hopefully run the scheduled backup successfully. Does that help?

    Thanks,
    Mike

    2 more steps


    @injaneb, thanks you put me on the right track! In my case there were 2 extra steps:
    1. The extra EFI was not on the C disk but on the J disk (the target of the backup) which was an external USB. I don't know why an EFI was made there. To remove that EFI partition, follow these instructions [1] carefully. I needed only the instructions using the built-in diskpart tool. Just make sure you selected the right disk!
    2. Before redoing the backup, delete the files on J: (the target disk) that were created by the previous botched backup. Their existence would cause exactly the same error code to show up.
