I have found a partial solution. I went to HP’s website and found that Recovery Console Command Prompt commands are available in Vista.
I booted from the Vista dvd, system repair, command prompt, and ran the following:
and the system booted up to a Windows update screen that said “Configuring update 3 of 3”. I suspected that this may have had something to do with recent Windows Updates, as I found references to this problem when Googling. I suspect perhaps the system was shutdown during the update?
Anyways I thought I was home free. The login screen came up, I logged on, much to my dismay the system hung for a minute or two at the Welcome screen, then faded to a black screen with only the mouse pointer showing. Strangely enough Ctrl-Alt-Del brings up the screen with “Switch User, Task Manager, Log Off, etc”, but the normal desktop is just black. I cannot get to Task Manager. I can however boot in Safe Mode. No Restore Points are available. I uninstalled the 3 most recent MS updates, no change. I downloaded the latest video driver from NVIDIA’s website, no difference. Last known Good doesn’t work either. At this point I’m at a loss other that trying a complete System Recovery. Any other suggestions would be most appreciated.
Since this is a somewhat different problem, perhaps I should start a new thread?
