Hallo. I have an epic laptop with a broken battery and in the middle of a windows update the power cord got out. After that I cannot go into windows. At first, I tried to restore the system with the troubleshooter, but it asked to connect with administrator account. Since there was not one, I could not procced to restore the system. There is nothing important to lose so finally I decided to make a new installation of windows. The problem is that after the laptop starts only in EFI Shell environment. I tried to figure out the way to install windows, but it seems that the boot manager is missing. How can I install windows 10 in such a case? I appreciate any help‼!
