Hey, So i upgraded from win 7 home to windows 10 due the procces computer rebooted and i keep getting error 0xc000000f. I cant pass this screen. When i tried to do a fresh install of win 10 from usb it does installs fine and windows works but i cant activate it, so i installed 7 again and used the upgrade option and now getting: File:\Boot\BCD Error code: 0xc000000f. When im trying to try to repair it from win 10 install is says my drive is locked and i need to unblock that. Any help? *EDIT* when i tried to go to fresh install again it seems that my drives are clean and have nothing installed on (this after i used the upgrade option).
