If you are reading this post, I guess you’re experiencing a windows boot failure, with a BSOD (Blue Screen Of Death) and error code 0xc000021a. You’re in a panic, and you’re googling for a fix.
If this the case, you’re at the right place for finding the fix.
I, my self, experienced a Windows 10 boot failure, causing a BSOD, with the following message:
“Your PC ran into a problem and needs to restart. We’re just collecting some error info, and then we’ll restart for you.“
at the bottom of BSOD was the error code: 0xc000021a
How to Fixe this problem?
After Windows 10 show the BSOD, it starts generating the memory dump file, under “C:\Windows\Minidump”. Just after that Windows 10 will start the WinPE environment.
In the WinPE menu, click “Troubleshoot” icon;
On the next menu, click on “Advanced options”
On the Advanced options menu, click on “Command Prompt” icon;
On the command prompt, type the following command:
“BCDEDIT“
This will display your boot parameters, such as your Windows partition and your Windows folder.
You need this information for use in the “SFC” command to repair broken or corrupted system files.
In my case the system partition is on “D:” and the system folder is “\Windows“.
Now type the following command to start scanning and repairing the system files:
sfc /scannow /offbootdir=d:\ /offwindir=d:\windows
This command will repair the Winlogon.exe and csrss.exe files that the integrity was corrupted.
What next?
