Windows 7: Unable to boot, error 0xc0000428

Unable to boot, error 0xc0000428

Hello all,

My computer (Dell Latitude D830, running Windows 7 Enterprise 32-bit) won't boot. The situation arose after a BSOD incident, but I have been trying for months to fix it and think I'm getting close. The auto-recovery tool on the install disc has not been able to fix anything. I have searched quite a bit on sevenforums for my error below but haven't found a solution that works for me.

Currently, upon booting I get error code 0xc0000428 for \Windows\system32\winload.exe. This screenshot is identical to mine:



I am unable to get past this screen, so tried using the command line on my installation disc to try and disable driver signature enforcement. I navigated to \Windows\System32 (where bcdedit.exe lives, not sure if that was necessary) and tried these commands:

bcdedit.exe -set loadoptions DDISABLE_INTEGRITY_CHECKS
bcdedit.exe -set TESTSIGNING ON

both return the same:
"An error occurred while attempting to reference the specified entry.
The system cannot find the file specified."

I also tried
sfc /scannow

which returns
"There is a system repair pending which requires reboot to complete. Restart Windows and run sfc again."

Restarting of course just puts me back to square one.

I even tried to force the scan by using SFC /SCANNOW /OFFBOOTDIR=C:\ /OFFWINDIR=C:\Windows

which produces "Windows Resource Protection did not find any integrity violations." Does anyone have any tips on where to go from here?

Have you reported this problem to your I.T. Department? They might be able to help you.

Code:
bcdedit.exe /store C:\boot\bcd  /set  loadoptions DDISABLE_INTEGRITY_CHECKS
bcdedit.exe /store C:\boot\bcd   /set  TESTSIGNING ON
replace C with your actual boot disk letter!

Because you are using Windows 7 Enterprise I highly recommend contacting your IT Department before changing anything.

Ah, thank you very much, Kaktussoft! I will try that later tonight when I'm home and see if that fixes the issue.

Layback Bear, I appreciate the input. Although I'm using Enterprise, it's actually a personal computer. I have the license to use it through my university. So I get to mess around with these fun things as much as I want!

Boot into System Recovery Options and select "command prompt"
or Advanced Boot Options using F8 trcks (repair your computer->command prompt)

Attached to this post is a screenshot of my output for both your suggestions. My disk partitions appear healthy and the changes to the bcd commands didn't seem to change anything. Is my syntax correct for those? Or do I need to be in a different directory? The C: drive is definitely my booting partition.

Code:
 
diskpart
sel  vol  c

Is that partition active?

Code:
 
bcdedit/store  c:\boot\bcd  /enum  all
Code:
 
bcdedit/enum all
Code:
dir  c:\boot\bcd
dir /ahs  c:\boot\bcd

In win7 recovery environment:
Code:
c:
attrib -h -s bootmgr
ren bootmgr bootmgr.old
If both commands succeed succesfully bootmgr file c:\bootmgr isn't there anymore. But it's there with name bootmgr.old (just to keep it)

Now reboot to recovery environment again and perform a startup repair. Your winload.exe and bootmgr are out of sync for some unknown reason. Startup repair puts a fresh copy of bootmgr on C. Try to boot normally afterwards

What did you do just prior to problem appeared? such problem can appear if you install win8

Here are screenshots of the output. The partition is listed as active. I couldn't fit the actual commands for
Code:
 
bcdedit/store  c:\boot\bcd  /enum  all
Code:
 
bcdedit/enum all
on the screenshots of their output, but the attachments follow the order of your suggestions and they produce the same output anyway. I will respond to your most recent post about bootmgr as soon as I'm home again. Thank you so much!
