Thank you very much for providing solutions. It's finally solved for me. For anyone interested I accessed the partition on windows and overwritten the two efi files. Followed guide shown in this youtube video

Cheers!

Hello! I know it is an old thread, but I have problems with boot when installing this security update (2017-003) on Yosemite 10.10.5.
Also, clover r4630 is installed, and the same problem appears (as i understend, there should be fix from r4147).
So, will replacing *.efi files help here?

Thanks everyone!
