How to restore windows on Mac?

Question

Windows

Good afternoon, help me solve the problem, my father has a Mac book pro 2015 with windows 10, he decided to climb through the registry and changed access rights from system to administrator (without making a backup) after that, immediately after the windows boot screen, a black screen!

Who knows how to solve the problem? I really don't want to lose my data!

Thanks in advance.

Answer 1

You can try to catch the right moment and by pressing f8 it will boot into the recovery screen, then go to the console, run regedit and by connecting the registry branches of the main axis to fix the registry.
You can boot into any guest axis and pull data.
Or on a poppy it is impossible to boot from a USB flash drive?
