I don't recognise this as a "well-known" problem during Vista setup, but ...
0xC000021A means STATUS_SYSTEM_PROCESS_TERMINATED:
http://msdn2.microsoft.com/en-us/library/ms854951.aspx
.... indicating that something has caused Winlogon or CSRSS to terminate.
These are the core user-mode proceses of Windows. There was one issue which
could cause this, first noted back in NT 4.0 days:
http://support.microsoft.com/kb/158376
and I believe the same problem, or a similar problem, could continue to
exist in Vista.
I guess you're doing an Upgrade of your XP system,, to Vista? One possible
workaround would be to do a clean install:
- back up all your user data to a safe location;
- run Vista Setup and elect to do a clean new Install, not an Upgrade to XP
- elect to reformat your C: drive
- proceed with Vista setup.
- when setup is complete, restore your backed-up user data into your new
Vista user directory.
- re-install any applications you had running under XP.
Vista will now be installing onto your machine as onto teh bare metal
hardware, without any interference from the previous XP installation. This
will remove many possible causes of the 0xC000021A error. If you still get
the error after that, you'll at least know there is a very fundamantal
hardware problem. Obviously re-installing your apps etc is a bit of a hassle
but it may be much quicker than trying to debug the error you're getting
while upgrading.
Other folks may have extra/better ideas .... hope this helps a bit.
