PSA I recently sent out. There was one group of people who did not see the humor in this.  :D

The "bcd" is boot configuration data. It's what the boot loader uses to find the parts that it needs to start the boot process. That's what got backed up, the current boot config info. Seems like in your case, part of that is missing.

If you are willing to wipe and rebuild, you could try doing these two commands:

bootrec /fixmbr
bootrec /fixboot

and then follow with the bootrec /scanos and bootrec /rebuildbcd. Since your system is actually running the boot code up to the point where it is looking for NTLDR, I am not sure if this will help, but it doesn't take long.

At any rate if you wipe and rebuild, at least you'll have a clean environment again.It's just a pain to reinstall stuff, although it gives you a chance to revisit the programs you use.

If you boot to the installer and go into the command prompt in the troubleshooting section you can try some things. If your box isn't seeing the loader then you can try to set it up again.

bcdedit /export c:\bcdbkup --- never hurts
ren c:\boot\bcd bcd2.old --- you don't necessarily have to do this, this renames the existing file so it doesn't get looked at
bootrec /scanos --- verify that it finds a windows installation
bootrec /rebuildbcd --- reply yes to add, exit to restart

Hopefully that would get you farther along. Sometimes "things happen" but it is always concerning when you can't even start to boot.
