How to resolve 0xc000021a (STATUS_SYSTEM_PROCESS_TERMINATE)

Question

I am having a huge problem that my windows 7 is not loading.

I had uninstalled my bluetooth driver and then tried to reinstall it. The problem started then that all the folders from libraries vanished and windows explorer tab did'nt work.

So I restarted my computer and then got this error The boot selection failed because required device is inaccessible

I tried system repair from windows dvd but it could'nt correct the error.After repairing stopped I got blue screen showing fatal error with code c000021a and message STOP . However after some time the message has reverted back to the previous one of boot device."

As an aside I have dual booting with ubuntu installed and ubuntu is working absolutely fine.

When I try to load windows in safe boot it shows that it tries to load some driver file and then gives the above mentioned error....

I have dell inspiron laptop and have done all the memory diagnostics inbuilt which are shown as having been passed.

How can I try to make windows work.....Please help and do tell if any other information is required...

Answer 1

Use a W7 installation DVD, boot from it and try a System Restore, pick a date before the boot problem started.

STATUS_SYSTEM_PROCESS_TERMINATED occurs when a user-mode subsystem, such as WinLogon or the Client Server Run-Time Subsystem (CSRSS), has been fatally compromised and security can no longer be guaranteed. In response, the operating system switches to kernel mode. Microsoft Windows cannot run without WinLogon or CSRSS. Therefore, this is one of the few cases where the failure of a user-mode service can shut down the system.

Mismatched system files can also cause this error. This can occur if you have restored your hard disk from a backup. Some backup programs might skip restoring system files that they determine are in use.

can be resolved by:

If the error occurs during system startup, restart your computer, and press F8 at the character-based menu that displays the operating system choices. At the resulting Windows Advanced Options menu, choose the Last Known Good Configuration option. This option is most effective when only one driver or service is added at a time.

If this does not resolve the error, try manually removing the offending software. If the system partition is formatted with file allocation table (FAT), use an MS-DOS startup disk to gain access to the computer's hard disk. If the system partition is formatted with NTFS file system, you might be able to use Safe Mode to rename or delete the faulty software.

If the faulty software is used as part of the system startup process in Safe Mode, you need to start the computer using the Recovery Console in order to access the file. If a newly installed piece if hardware is suspected, remove it to see if this resolves the issue.

Try running the Recovery Environment and allow the system to repair any errors that it detects.
