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...

Solution

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

I have later found out that this is an issue with the bluetooth driver given by dell on their download page.... As soon as you try to update or uninstall it , it begins to delete everything from your system drive...

Hey ... Thanks for the reply but I have read this and unfortunately none of it is helping..... How to manually remove any software when windows does'nt load.... Trying safe boot too does'nt work as I said.... And as I said that no recovery is being made using startup repair..... Thanks a lot but for your reply...

Then I would suggest a live CD or in the worst case a repair or reinstall, it seems very broke. Who knows your disk might be failing...

But at the same time ubuntu is running fine..... Also if i reinstall is there any way to gt ubuntu grub back

@user57162: I saw your other question, no need to mix them. If you just reinstalled Windows 7 I guess it is no problem to reinstall it once again, try to get the latest stable Bluetooth drivers this time and install them after you installed other things and perhaps made a back-up...

It would be much easier if you simply posted what actually solved the problem for you instead of posting everything you tried.
