I bought a new bigger SSD for my Windows 8.1 computer and I tried cloning the C drive to this new SDD using Ease Todo. Everything seemed fine until I restarted my computer after unplugging the original SSD. The computer displayed a BAD_SYSTEM_CONFIG error which I have since been able to fix. I was then getting a boot configuration data missing error. I have followed advice I found online asking me to try the bootrec method of fixing this problem but it didn't work for me. I then removed all my hard drives but the original C drive and now when windows loads I only have a black screen after the BIOS. I made a recovery USB but none of the troubleshooting options work for me (errors or unsuccessful attempts). I am at a loss as to how this happened (I thought cloning a drive would be simple!) and I have hit a brick wall. Any help or advice would be greatly appreciated.
