Problems with Windows 10 after updating it on dualboot

I'm using dual boot which includes Ubuntu 16.04 LTS and Windows 10, ver. 17.03. Having updated Windows and waited for long to get "work with updates" done, I restarted my laptop and noticed that Windows cannot load(black, then purple screen, that's all). Even after using "rude" powering off it reloads but recovers the previous version. What can you advise me to do to successfully load Windows, but in the latest version? Thanks.
