Windows 2003 logo appears then reboots after updates

I have a Windows 2003 Server that fails while rebooting. 2003 Server logo appears for 2 seconds, then it displays a grey screen and always reboot. No way to use F8 while 2003 logo appears, then server force reboot at gray screen.
Trouble is since user download last MS updates, install them automatically, then reboot server just when prompted to reboot. User didn't wait to click reboot button when prompted.
All data still available on disk. I made a clone on another disk. Tried to use 2003 CD to process a CHKDSK at prompt, but don't know what else to do now.
I'm trying to find a way to enable 2003 boot without need to reinstall all applications and data.

You must press F8 before the logo appears.  You will get more time to do it if you power off and start from a cold start.  One of the menu choices is to disable automatic restarts so you can see a blue screen stop message.  Others will be last known good which may help here.

Two lessons here.  Always restart before applying updates, and always have a current backup before applying updates.

thanls a lot. Thought about it. F8 before logo appears = nothing else happens. I did power off and start from a cold start. There is no menu choice. Unfortunately no any blue screen stop message.

As I can access BOOT.ini file from another computer, I'm thinking about a way to change its contents, to allow F8 menu and disable automatic restart upon system failure...

I agree with you about restarting before any update, and having current backup. User didn't care.

Is this server a terminal server?  If so there is a known issue with KB 3045999.  In some cases it is affected even if not a TS.

Thanks a lot again.

It's a x64 FR 2003 R2 standard server, but terminal server service was not installed on it.

Sounds great about how to remove update from the recovery console, I'm about to use BATCH spuninst.txt

I had one killed by that KB.  It was also 2003x64.

Congratulations !
You were right: everything worked fine.
Server boots fine now, I could process all updates.
I'll keep a backup for the user.
Thanks a lot again for your support
