I am working on a HP laptop, running Vista Home Premium.

I was updating AVG to AVG 2011 and after it asked to reboot I got the bsod c000021a.

I am unable to boot into safemode, I get the same bsod.
Tried Last Known Good Configuration and that failed.
Also tried several different restore points but kept getting the msg "System failed due to unspecified error. The system cannot find the file specified. (0x80070002)"

It will boot into the Recovery Partition after the bsod, but Startup Repair says it is unable to fix the problem.

I can get into the F8 menu and that is about it.

Help?

Thanks for the reply.
That would be great if I could boot into Windows! I guess you didn't read the post that well... or I didn't make it clear I was unable to boot into Windows at all.


Anyway, after much research, I found a solution that worked without having to re-install Vista like I was afraid would happen.

boot from the Windows Vista disk in repair mode, and choose to start a Command Prompt then type:
CD \Windows\System32\Config [enter]
move Software Software.bad [enter]
move Regback\Software [enter]
exit [enter]
and reboot.
Click to expand...
Hope this helps other that may have the same problem.

There are other ways to do this also, so if anybody want more options, let me know.
