After automatic update to Sierra 10.12.6, Dual booted Windows get stuck on blinking cursor!

Hi! Unfortunately my hackintosh decided to automatically install the update 10.12.6 from 10.12.4 and I had to reinstall some kext files to get things back to work.

My dual booted Windows that previously worked stopped working, and is stuck on this screen (blinking cursor): https://i.stack.imgur.com/3T1Pa.jpg

Note that Windows previously worked! In Clover, I tried to change to Legacy Boot (https://imgur.com/a/lyzw4) but now I get "Press any key to boot from DVD/.." black screen error.

Any idea how I can get Windows back to work?
