Without being able to look at your system, the only thing I have to go on is the 0xc000000f error - which presumes that the winload.efi file is either missing or located in the wrong place.
Until this is fixed, I'd suggest that you boot your system by pressing F8 and selecting the drive to use.
The system seems to be OK, it's just the boot stuff that's messed up.
I am not a BCD or boot sequence expert. I would suggest that you start a new post in the Windows 10 forum titled something like "BCD help needed" and describe how the system successfully boots.
You need help with reconstructing the boot stuff.
Another option is to try a Refresh of the operating system.
That might help the boot stuff without erasing your files.
If you can't find someone who's good at the BCD/boot stuff, then you may have to resort to a Reset of the system (which will wipe out all of your data)
But that's not essential at this point as you can still boot to Windows.
FWIW - here's a link on how to export and rebuild the BCD: https://support.microsoft.com/en-us/kb/927392
Search the web for "boot rec /rebuildbcd found Total identified Windows installations: 0" (without the quotes)
That may help to find help with this.
