W10 won't boot

I'm dead in the water without a paddle !
Upgraded my Toshiba laptop from Windows 7 to W10. Worked fine for 4 days. I downloaded and installed windows 10 firewall control app. It said it needed to close all apps including Windows Explorer. So I let it. It did its thing but seemed to hang. So I finally pressed the power key and it took me to the screen asking for my boot password. I entered it and then got a blue screen of death saying :

RECOVERY
Your PC needs to be repaired.
The Boot Configuration Data for your PC is missing or contains errors.
File \Boot\BCD
Error code 0xc000014c
You'll need to use recovery tools. Etc.

I don't have recovery tools!
I did create a system restore but can't get to it.
The laptop's hd contains a recovery partition but I don't know how to get to it since it won't boot and I don't know if it's a recovery for W7 or W10.
I also have an image backup on a hard drive which I made with EaseUS Todo Backup but again no way to access it.

Is this salvageable? Please help.
