Windows Failed to Start, winload.exe 0xc000000f
Hi Folks,
I have a pretty serious problem that I've already gone through a number of steps to try and remedy, to no avail. I'll go through the history and let you know where I am now.
My computer crashed about a week ago - I cant remember exactly what it said, but I believe it went through the usual "fatal error" blue screen of death stuff and something about a crash memory dump. I turned the computer off during the memory dump because it seemed to have frozen. This happens with relative frequency with this computer, usually brought on by overheating. Usually the regular automatic recovery fixes the issue (at least temporarily).
This time however I got the "Windows Boot Manager" error when I started up the computer next. With "Windows failed to start...Insert your windows installation disc..."
I can't remember the file, code, or info. But automatic repair was failing with these details:
Automatic repair failed with these details:
Problem Signature 01: 6.1.7600.16385
Problem Signature 02: 6.1.7600.16385
Problem Signature 03: unknown
Problem Signature 04: -1
Problem Signature 05: External Media
Problem Signature 06: 1
Problem Signature 07: Missing Boot Manager
OS Version: 6.1.7600.2.0.0.256.1
Locale ID: 1033
it may have been something with the bootloader since I ended up following all the instructions here: https://neosmart.net/wiki/recovering...ws-bootloader/
I rebuild the bootloader with all the "nuclear holocaust" instructions, but now when I go to boot from the HDD I get the same "Windows failed to start..." screen with:
Files: \Windows\system32\winload.exe
Status 0xc000000f
Info: Selected entry could not be loaded because the application is missing or corrupt
Running auto repair from the recovery disk gives me:
"Startup repair is unable to repair the computer automatically" with the details:
Problem Event Name: StartupRepairOffline
Problem Signature 01: 0.0.0.0
Problem Signature 02: 0.0.0.0
Problem Signature 03: unknown
Problem Signature 04: 0
Problem Signature 05: unknown
Problem Signature 06: 1
Problem Signature 07: unknown
OS Version: 6.1.7600.2.0.0.256.1
Locale ID: 1033
The Startup Repair diagnosis and repair log gives:
Number of repair attempts:1
System Disk = \device\harddisk0
Windows directory = C:\windows
AutoChk Run = 0
Number of root causes = 1
Every test is completed successfully until
"Boot configuration is corrupt
Repair Action: Partition table repair
Result: Failed Error code = 0x490"
I tried following these instructions: https://neosmart.net/wiki/winload-exe-missing-corrupt/
bootrec /rebuildbcd gives me:
"Successfully scanned Windows installations
Total identified Windows installations: 0"
sfc /scannow gives me:
"There is a system repair pending which requires reboot to complete. Restart Windows and run sfc again"
but I get that every time, regardless of attempting any other repair.
I also tried using the Easy Recovery Essential Tool recommended on that page and others. When it comes up with volumes to repair none of them have valid windows installations either.
I also followed the instructions here: Troubleshooting Windows 7 Failure to Boot
and get to here: Use Bootrec.exe in the Windows RE to troubleshoot startup issues
When I run /fixmbr and /fixboot I get "operation completed successfully"
when I run /scanos and /rebuildbcd I get "successfully scanned.... total identified...0"
I followed these commands as well:
- bcdedit /export C:\BCD_Backup
- c:
- cd boot
- attrib bcd -s -h -r
- ren c:\boot\bcd bcd.old
- bootrec /RebuildBcd
but there is already a bcd.old file (I must have done this before) and /rebuildbcd give me the same "total identified windows installations: 0"
bootsect /nt60 sys gives me a successful message but booting from the HDD gives me the same error and system repair gives me the same errors as well.
I can't follow step 7 because I can't boot into safe mode, and I haven't tried steps 8 or 9, because I figured I would check here first.
Thank you all very much for your help - happy to try and post anything.
