I have had win 10 on my laptop 5 months or so being upgraded from win 8, 8.1 etc. In this time I have not been able to backup to my (eSATA) external HD. I need to do some program work so I want to back up before going ahead. Before someone says use this or that backup program to accomplish the backup. My desire is to have win 10 able to function properly before taking another road.
When I tried my back up this morning it looked like it was running through the whole process but in the end it said failed to backup, giving code 0x807800C5 . My backup location has 3tb so there is plenty of room for it.
Thanks for any info

Hello Terry,
Can you post a screenshot of your disks and partitions using the disk management window? I am wondering if you might have some partitions that are causing problems with the backup such as multiple EFI system partitions.
Recommended method for disk management screenshot so we see everything we need to:

Not sure what is going on with trying to get an image into here. I'll see what happens with this
maybe this time
If you are lucky that may be the case at a later time. Right now I recommend alternate programs. I use free Macrium.My desire is to have win 10 able to function properly
You have to decide wether you want to have your problem solved or wait for a useable Windows solution.
Ok,
My OS has always been on C:, my backup is to drive H:
32gb ram, this computer shipped with win 8, which I took to 8.1 and then 10.
It took me a couple of hours just to get this screen shot if that tells you anything
See post #2 here:
system image backup, 807800c5 error - Windows 10 blog
You have an unused EFI system partition on your disk #2 which is also the disk which contains your H: drive. That's probably what your problem is.
For you:
Right click on start icon, click command prompt (admin)
Type:
diskpart
select disk 2
list partition (find what is the number of your the partition labeled as system)
select partition X
del partition override
exit
exit
The select partition X above is probably going to be select partition 1. Just make sure it is the small EFI partition and not the big H: drive partition.
Thanks for all the help so far. However I have made the disk partition changes on disk 2 EFI partition and changed it a basic drive J: volume. I tried to do another back up and find the same problem ??
How did you change it to a basic drive J: volume? Why didn't you just delete the partition?Thanks for all the help so far. However I have made the disk partition changes on disk 2 EFI partition and changed it a basic drive J: volume. I tried to do another back up and find the same problem ??
