I have a Samsung laptop with WIndows 8 but it won't boot, all I get is a message: Your PC needs to be repaired. The boot configuration data for your pc is missing or contains errors. File:\ EFI\Microsoft\Boot\BCD Error code: 0xC0000001 It stays on the screen for some seconds and then reboots. I have tried booting with a Windows 8 disc but the same happens, I have turned off secure boot in the BIOS and the same happens, whatever I seem to try it keeps coming up with the same message so I am at a loss to get past this error message. I am hoping you guys will have the answer.
