Hi there,


I have a dual boot PC with ubuntu and Windows 10. When starting up Windows it began updating and got stuck at 77%. I let it continue for quite a while but even the dots stopped moving. I then stopped the computer. When restarting it in Windows, I get a blank screen with a blinking prompt in upper left corner. No response to typing, no cmd, nothing. It will only respond to Ctrl+Alt+Supr, to restart again.


How can I recover Windows 10? Please note that my PC works perfectly fine in Ubuntu. I am writing this post from it. I would like to keep the dual boot while recovering Windows. Is it possible to do it without reinstalling it?


THanks,
