For months, I was able to dual boot Windows 7 and Windows 8 on my laptop. Both are on different partitions on the same hard drive. I primarily use Windows 8 and I almost never boot on 7, but it is there.
Yesterday, I decided to boot on Windows 7. As I was leading to the "Choose operating system screen" of Windows 8, I got to a blue error screen that said Windows 8 was unable to load. (Error code 0x0000225, missing winload.exe.) I tried refreshing via a bootable USB, but it failed. Thankfully I was able to boot to Windows 7. I switched the default OS to 7. At this point, whenever I boot, I get to choose between 7 or 8, in which 8 leads to the error screen.
I tried fixing the problem by recreating the BCD file, but afterwards, the computer doesn't recognize that I had a Windows 8 partition anymore (it doesn't let me choose between 7 or 8 on boot at all).
Is it possible to boot onto Windows 8 again? I have important files on that partition.
Extra Information: The partition that was Windows 8 now shows up on Disk Management as "Free Space".
