HELP!!! Error Code 0xc000021a !!!

Hi ooldog,

It seems like the operating system is corrupted. You can refresh the system to check if the issue resolves. Switch ON the system and switch OFF the system 3 to 4 times when the Dell logo appears. This will make the system to go into **Windows 8 Advanced Startup Options** screen. Please select **Troubleshoot** option and choose the **REFRESH** option so that it refreshes the windows operating system.

Also, I would suggest that you run the diagnostics on the computer by following the steps mentioned in the video below and check if there is any issue with the hardware on your system.

hi Ravi BC,

• Your PC ran into Problem and it needs to restart. We're just collecting some error info, and then we'll restart for you.
• error. 0xc000021a

After it automatically restart it says

• Automatic repair couldn't repair your pc
• press Advanced Options to try other options to repair your pc or shut down to turn off your pc.
•  Log file: C:\Windows\System32\Logfiles\Srt\SrtTrail.txt .

i pressed advanced options and selected troubleshoot , on selecting troubleshoot it led me to refresh your pc on selecting it , i was led to choose an account to continue, on selecting it , it shows Dell, on clicking on Dell , it says, Hi Dell, enter the password for this account.

now the thing is i didn't have any password for my system............ so what to do??

There isn't any fix for ransomeware passworded machine. You have to reinstall using restore media.

error. 0xc000021a

"The drive where Windows is installed is locked.  Unlock the drive and try again.

Reset: "Unable to reset your PC.  A required drive partition is missing."

c:\windows\system32\Logfiles\Srt\SrtTrail.txt is a windows 8 log.

the error was always caused by failed Winlogon.exe or Csrss.exe

It can also be caused by trying to install full windows 8 with a windows to GO usb flash drive.

Hi Ravi,

as you suggested , i successfully ran the diagnostics. i did a quick scan and everything was all right except the note book panel

i didnt want to perform pc restore as it will lead to complete data loss and i dont want to lose my files.

 When I try the shift f8 option it goes to the the diagnostics. so i cant Disable Driver Signature Enforcement.

Hi ooldog,

You will need to get in touch with a local technician to back up the data from the system and reinstall the operating system.

Please private message me the system service tag if you do not have the operating system disc so that I can check and send you the disc as an exception.

hi  Ravi,

i have os disc, how do i backup my data from the system??

any help is much appreciated.

Hi ooldog,

To back up the data you will need to connect your hard drive as a secondary hard drive to a different compatible system.
