Dell 3520 Crashed

My 3520 had a popup asking me to upgrade to Win 10. I selcted "not at this time"....my computer went to a blue screen first telling me I had lost "boot command"...it then went to a black screen telling me the Boot Configuration Data was missing.
My Win8 recovery disk does nothing but finish the install and then tells me the installation can't continue and contact my net administrator or Dell Support. I have tried a fresh install of Windows but same thing...I get the following:

File: \Boot\BCD

Status: 0xc000000f

Info: The Boot Configuration Data for your PC is missing or contains errors.

Any ideas?

Thank You
