Ways to Fix “Windows Stop Code 0xc000021a” Error
Run a BSoD fixer
As we’ve already said, it’s hard to say what caused this stop error. To gain more time and fix the BSoD quicker, we recommend running a general blue screen troubleshooting tool. Restoro is run by an online database that has the latest system files that work on Windows 10 computers. This makes it easy to replace any parts that can cause a BSoD error.
This software can also help you by creating a restore point before starting the repairs, enabling you to easily restore the previous version of your system if something goes wrong. This is how Restoro can be used to fix registry errors:
- Download and install Restoro.
- Launch the application.
- Wait for the software to identify stability issues and possible corrupted files.
- Press Start Repair.
- Restart your PC for all the changes to take effect.
Unplug all peripheral devices
Peripheral devices are another possible cause of critical system errors that can’t be ruled out. The loading process can sometimes stop because of devices on the outside. Also, this stoppage can cause more than one error, such as the Blue Screen of Death crash with the 0xc000021a error code.
Some PC problems are hard to fix, like when repositories are broken or Windows files are missing. If you can’t get rid of an error, your system may be broken in some way. We suggest installing Restoro, a tool that will check your computer and tell you what’s wrong.
So, when booting from a USB or DVD, make sure that only the mouse, keyboard, and monitor are plugged in. You should turn off everything else, just in case one of the other devices is stopping Windows 10 from being installed.
Create a bootable drive again with genuine Windows
What comes first? If you can, try putting Windows 11/10 back on another computer. That’s the best way to find out if your bootable drive actually works. The process is the same whether you use a DVD or a USB thumb drive.
If at least one PC can boot, the problem is with the other PC. In this case, the installation drive is likely set up and made properly. If you can’t boot on any of the devices you’ve tried, make sure to install Windows 11/10 from scratch on a bootable drive and try booting again. Follow these steps if you’re not sure how to do it right:
- Download the Media Creation Tool.
- Plug in the USB flash drive with at least 4 GB.
- Run the Media Creation Tool and accept the License Terms.
- Choose Create installation media (USB flash drive, DVD, or ISO file) for another PC.
- Select the preferred language, architecture, and edition.
- Click Next.
- Choose USB flash drive and click Next.
- Wait until the installer downloads the files and, finally, you’ll have a properly created and configured bootable drive with Windows 11/10 installation.
Upgrade via the OS
- Download the Media Creation Tool.
- Run Media Creation Tool and accept the Licence Terms.
- Choose Upgrade this PC and the downloading process should commence.
- Once it downloads files, Media Creation will start upgrading.
Run SFC
- Press the Windows key + S, type cmd, and click Run as administrator under Command Prompt.
- Type the Command below and hit Enter:
sfc/scannow
- Wait for the scanning procedure to end and look for improvements.
