I've written several messages on acronis's site and to tech support. They
don't answer. And I have their tech support for several months. I also have
threads on several forums. The problem proved to be complex. Maybe because
GPT and EFI are still fresh concepts and everyone's still thinking in terms
of MBR.

I thought I had logs to understand what happened but it seems that
operation was not logged.
The next step is to try load windows with edited bcd because right now it
does not load and it has no such mode as grub rescue to point to correct
partition.

Quite possible. It was a surprise for me when I chose to resize *adjacent*
partitions and acronis decided to move around some stuff. I should have
made a photo of the error then. I thought it works like transactional
database and does not break anything. I was wrong - it broke NTFS on my
windows D:. I could not recover MFT (Master File Table with files
locations) and did quick format as last cause. There is no valuable data,
just a lot of installed programs. Also hoping chkdsk /f might add missing
files back to MFT.

Thanks, you've helped a lot with my understanding of the problem. I will
write once this is solved.
