Fatal Error C0000003A applying update operation 18843

Question

My Asus Windows 8 had an error while updating and nowit won't boot. It becomes stuck in the process o updating. Now, while trying to launch the automatic repair me u nothing happened. The screen froze. 

After removing the battery and turning the computer off, and then reinserting the battery, we were able to access CMOS.

I'm becoming more and more distressed by the prospect of wiping back to factory defaults, since this computer has much of my unbacked up art work on it.

Hi,

Thank you for posting the query in Microsoft Community and we are glad to help you.

As per the issue, you get an error message “boot configuration data file is missing some required information” along with the error code “0xc0000034” when you boot to the computer.

I would like to gather some information on this issue to get a clear picture:

Did you make any hardware or software changes to the computer prior to this issue?

Perhaps, Windows boot files might be missing which are important to boot into the computer.

If automatic repair doesn’t help to repair the startup files, you may try to repair them using these commands through Command Prompt under Advance Options.

Refer to the steps:

a) After you boot your computer using Windows 8 DVDor System Repair Disc, a black screen appears with gray text "Press any key to boot from CD or DVD". Press any key.

b) Select the correct time and Keyboard type.

c) Click Repair your computer in the lower left corner.

d) Select Troubleshoot from Choose an optionscreen.

e) Click Advanced options in Troubleshoot screen.

f) Click on command Prompt.

g) Type these following commands and hit enter after each line of command:

Bootrec /fixmbr

Bootrec /fixboot

Bootrec /scanos

Bootrec /rebuildbcd

Please reply us if the issue still persists.
