So two days ago I decided to format my laptop and install windows 8.1 on it. On first boot everything was fine, great even. But on second boot I got the dreaded black screen. It won't log into windows, and I immediately get a black screen right after the bios screen. I can't access safe mode; tried holding shift + f8 and it doesn't do anything. Loaded windows into a USB drive and tried the bootrec /fixboot and /fixmbr commands, both of which reported successful and didn't fix the issue at hand, mind you rebuildbcd says it can't detect a windows installation. There are no restore points and I can't refresh windows because it says the drive is locked. What can I do to resolve the issue at hand? Is there a way to get to the data on the drive and back it up before formatting? I did try plugging the hard drive to my desktop, but I can't access it's contents without having to format it.
