Just reset Windows 10 on my laptop because I was unable to sign into my Microsoft account therefore I couldn't access Cortana or the Store or any of the new Microsoft 10 features. Everything else worked fine. So I started the reset process and chose the option to save all my personal files, and the process went smoothly until it got to the end of the installation. Now it looks like I'm stuck in a boot loop and it has been going on for about 12 hrs now. I am going to go to work and hope it is finished resetting when I come home. Any help is greatly appreciated. I loved Windows 10 so far, I just needed to be able to sign into my Microsoft account.
