Hello. All out off sudden my Win10 computer stopped working properly. It was completely fine the day before, but over the night my computer stopped working. The problem is that when i attempt to start up my computer, it loads the BIOS, then the following error message occurs; "Bootmcr was not found". I've read on other forums that the fix would be to use the Win10 cdkey to repair the windows version, but i dont have any CD nor do any of my friends. So any ideas on how to progress further here?
