Cloning of 2nd disk messes up (EFI partition from 1st disk and only 2 of 3 from 2nd)

Thread needs solution

Have a huge problem making a clone of my 2nd disk (a HDD with 3 partitions).

When I select the source it show all 3 partitions (D: S: and W:).

I select the destionation (exact same disk type).

Now it shows a suggested layout with the EFI partition from my 1st disk, and the S: and W partitions from the 2nc). Why does it bring the 1st disk in here at all?

Any ideas?

Lars-Erik, are you attempting this clone from inside Windows?  Have you tried the same when booted from the Acronis bootable Rescue Media (booted in EFI mode)?

Cloning may be assuming that the target drive will be an OS boot drive to give the EFI partition layout?

This is one occasion where it would be recommended to do a full disk/partitions Backup of the source drive, then Restore that back directly to the Target drive - all of which can be done from within Windows and without using clone, with the added benefit that you also have a backup image to fall back on should either drive fail at another time.

A picture would help as well - I'm not exactly sure what you're seeing.  I don't see why it would see additional paritions of another drive - the source should only list the source paritions and the destination should only list destination paritions.  

If you are cloning disk 1 and it has an EFI partition scheme, whatever you clone to is going to have the same parition scheme.  A clone is essentially an exact copy of the original drive.  You cannot clone from EFI to MBR - anything on the second drive will be wiped, formatted and copied over exactly as it is from the original drive.
