microsoft update, now unable to start computer

  runnerpete 21:18 18 Sep 2008

At 4-30 pm today, my wife switched on our desktop, system windows xp home edition, and was advised of a microsoft update, together with the flashing shield emblem at bottom right of screen. The update was completed but the computer has failed to restart.It fires up and a message apologising that windows did not start successfully, and a note that hardware or software changes were a possible cause. Options available were to start in Safe Mode,or Safe Mode with command prompt, or Safe Mode with networking, or Last known good configuration, or Start Windows normally. We have tried all options with no success. The computer starts up but each time gets no further than the above page. Help urgently required please.(currently using a laptop) Thanks in advance. RP

Repair XP by install over the top of existing system

1. Boot the computer using the XP CD. You may need to change the boot order in the system BIOS so the CD boots before the hard drive. Check your system documentation for steps to access the BIOS and change the boot order.

2. When you see the "Welcome To Setup" screen, you will see This portion of the Setup program prepares Microsoft Windows XP to run on your computer:

To setup Windows XP now, press ENTER.

To repair a Windows XP installation using Recovery Console, press R.

To quit Setup without installing Windows XP, press F3.

3. Press Enter to start the Windows Setup.

To setup Windows XP now and Repair Install , press ENTER.

DO NOT choose "To repair a Windows XP installation using the Recovery Console, press R", (you Do Not want to load Recovery Console).

4. Accept the License Agreement and Windows will search for existing Windows installations.

5. Select the XP installation you want to repair from the list and press R to start the repair.

6. Setup will copy the necessary files to the hard drive and reboot.

Do not press any key to boot from CD when the message appears.

Setup will continue as if it were doing a clean install, but your applications and settings will remain intact.

Just browsing through PCA mag and realised that I had not responded to your very prompt reply to the above problem.
We are now back up and running again thanks to your information, so a very big thank you, and apologies for not doing sooner.
The experience of downloading a microsoft update and finding what happened as a result has however left me very wary of doing so again, as basically, we still do not know what caused the problem.
But again, many thanks for your help.
