First and foremost, forgive me if any of the following command returns are too vague or missing; I'm typing this up partly from screenshots and partly from memory. Happy to run any or all of them again or further requested commands to get more accurate results.
When I try to boot, I get a black screen that says "Preparing Automatic Repair," then "Diagnosing your PC," and then "Attempting Repairs," and then "Automatic Repair couldn't repair your PC" on a blue screen. There are two buttons: Shut down and Advanced options.
I tried Startup Repair via Advanced Options, but it said
Startup Repair couldn't repair your PC
I then tried
X:\windows\system32>sfc /scannow
Windows Resource Protection found corrupt files and repaired them. Details are included int he CBS.Log windir/Logs/CBS/CBS.log. The system file repair changes will take effect after the next reboot.
On reboot, it booted into Automatic Repair again:
Automatic Repair couldn't repair your PC
After disabling automatic repair on launch, it says:
A required file is missing or contains errors. File: \Windows\system32\winload.exe Error code: 0xc000000f. Choose one of the options below to address this problem: Esc for recovery, Enter to try again, or F8 for startup settings.
The following is a series of further command prompt commands I input with their outputs:
X:\windows\system32>bootrec /fixmbr
The operation completed successfully.
X:\windows\system32>bootrec /fixboot
The operation completed successfully.
X:\windows\system32>bootrec /scanos
The operation completed successfully.
Total identified Windows installations: 0
X:\windows\system32>bootrec /rebuildbcd
The operation completed successfully.
Total identified Windows installations: 0
X:\windows\system32>bootsect /nt60 SYS /mbr
Successfully updated NTFS filesystem bootcode.
Successfully updated disk bootcode.
Bootcode was successfully updated on all targeted volumes.
I rebooted at this point and it still said:
A required file is missing or contains errors. File: \Windows\system32\winload.exe Error code: 0xc000000f. Choose one of the options below to address this problem: Esc for recovery, Enter to try again, or F8 for startup settings.
I then booted from the Windows 8.1 installation media and ran the following commands:
X:\Sources>diskpart
X:\Sources>list volume
Volume 0: E: CD-ROM
Volume 1: C: System Rese Partition
Volume 2: D: Partition
X:\Sources>exit
X:\Sources>copy E:\mount\Windows\System32\winload.exe D:\Windows\System32\winload.exe
File(s) copied successfully.
I then rebooted and faced the same:
A required file is missing or contains errors. File: \Windows\system32\winload.exe Error code: 0xc000000f. Choose one of the options below to address this problem: Esc for recovery, Enter to try again, or F8 for startup settings.
I then tried the following:
X:\Sources>ren C:\boot\bcd bcd.old
The system cannot find the file specified.
X:\Sources>bootrec /rebuildbcd
Successfully scanned Windows installations.
Total identified Windows installations: 0
X:\Sources>bcdboot D:\Windows /s C: /f ALL

X:\Sources>chkdsk D: /f /r
