Windows Failed to start Status: 0xc000000f

When I boot into win 10 I get a black screen that says:
Windows Failed to start
Status: 0xc000000f

When I boot to a Win 10 Install disk I select:
English, next
Repair your computer
Troubleshoot
Advanced options
Startup Repair
It says it's Diagnosing problems
Attempting repairs
Startup Repair couldn't repair your PC.

What can I do to fix the boot up problem?

Thank you,

You have a problem with your Boot Manager. Do you have any form of backup? I have repaired mine using a windows 7 Boot Disk. If you have a DVD of your Windows 10 you can try booting to it and try to get to a CMD prompt and type in the following:

BootRec /FixBoot
BootRec / Fix MBR
BootRec / RebuildBCD

Do not use the last choice unless you have to.

Welcome to The Forum BTW::)

Thanks for the reply...

I tried that. It didn't fix anything.

When I get the black screen saying:
Windows Failed to start
Status: 0xc000000f
it also has:
file: \Windows\system32\winload.efi

I do have a dual boot with
Win10 on C:
Win7 on E:

The file C:\Windows\System32\Winload.efi is on the drive.
