Windows Server 2008 hangs up while booting after Windows update applied several updates. The server is a virtual instance on a Server 2008 Hyper-V host. Other virtual servers are fine, but have not been updated.
The normal boot shows the horizontal barber poll forever. When I do a safe boot it also hangs up. With a "Please Wait..." after loading many '.sys' files.
The last successfully loaded file listed is: '\Windows\system32\drivers\crcdisk.sys'
That is the extent of what I have been able to determine.
You can try to uninstall updates using Microsoft Diagnostic and Recovery Toolset version 6.0 or 6.5 (Windows Server 2008 R2).
