After a Windows update, I can't get to the Windows login screen, and arrive at a screen that states, "there is an invalid object in the boot configuration data store windows 8." The message suggests that I do a system repair from my Win 8 install disc. I booted to the disc and then, per Microsoft's suggestion, accessed a command prompt, where I tried bootrec /RebuildBcd. The command completed "successfully," but reported that no operating system was found. An automatic repair also failed. Is there anything else that I can try to get my system back? I can't boot top Safe Mode either.
I do have a Partition Manager backup. If nothing else works, can I copy the BCD fiiles from the backup over the ones in my presently-bad system? I don't use System Restore, and my backup is little older that I'd like. Thanks!!
