How to fix system error c21a windows?

Question

Windows

Computer shut down during Windows update. Now, after loading, a blue screen crashes with the following message:

When booting from an installation flash drive, the same thing.
When you try to rollback the system to a working version, the same thing.

Has anyone come across and know other solutions to the problem? I will be grateful for the answers.

Answer 1

faced on a broken Windows. computer after a couple of reboots booted from the Windows recovery partition in recovery mode and there I rolled back to the previous shadow copy. you either do not have a recovery partition, or you did not wait for the boot in recovery mode, or the Windows version is below seven.

Answer 2

They recently brought me a laptop with this error, they also cut it down in the middle of the update. All dances did not end with anything. in fact, the kernel of Windows is damaged. Reinstall only. With this error, all recovery tools turn into dust. in general everything.
