KB4512476 causes winload.exe boot loop on Server 2008 SP2 (Not R2)

August monthly rollup KB4512476 after install causes our Server 2008 SP2 box to fail with the below error:

File: \windows\system32\boot\winload.exe
Status: 0xc0000428
Info : Windows cannot verify the digital signature of this device.

I’ve found a workaround for the boot issue if you can get to the Windows recovery environment.

1. In the Windows Recovery environment open the command prompt

2. Type in BCDEDIT and record what the identifier is. Normally this is {default}

3. Type the following command BCDEDIT /set {default} nointegritychecks 1

  • Replace {default} in the above command if your identifier is different!

4. Reboot

Once you’ve booted up make sure to install the KBs listed in the 2019 SHA requirements post.

Once you have all required KBs installed run the following command to enable integrity checks again BCDEDIT /set {default} nointegritychecks 0
