I have a Gateway NE series laptop originally running Windows 8. I've had it since November and each time I turn it on a black screen with a blue box appears that says, "Windows Boot Manager, Boot failed.", the next screen says, "No Bootable Device. Hit any key." After hitting a key a grey screen appears that says: Boot option menu 1. Windows Boot Manager (Hitachi HTS543232A7A384) After choosing that option it brings me back to the first screen. Any help would be greatly appreciated.
