Cannot assemble EFI-based images

Hi all

I have an UEFI system running Windows 2008R2 with GPT style partition.

I am able to run image backups successfully without problem. However, I am unable to assemble the backups into a single vhd. There are errors and warnings as follows:

ERROR: NTFS magic wrong
WARNING: Volume not an NTFS volume. Copying all blocks…
ERROR: Trying to write beyond partition

I am using the latest version of server and client. I thought Urbackup currently supports EFI partitions? Why is it that the disk assembly fails?
