Best fellow surfuce pro users. I got from my girlfriend her surface pro to repair. She told me that from one moment the tablet had a blue screen. And asked politly if i could help her. Turning the device on gave me a blue screen that said recovery and gave me this information Your PC needs to be repaired The Boot Configuration Data file is missing some required information File: \BCD Error code: 0xc0000034 Only with the option to go to uefi setting when pressing the windows button. I dowloaded windows 8 and thought i was able to restore the file that was missing trought a bootable usb. The i found out that pressing the volume down key and then the on button would let me boot in the usb stick, this unfortanly didnt happen and now i am still stuck in the blue recovery screen with no options. ( the usb stick works fine on a windows laptop) I searched forums why i coudnt boot from the usb stick , called microsoft but didnt get any answers. Maybe someone in this forum could help me. I would be very gratefull.
