Win 8 64bit fails to boot after update
 

This is the second time in 5 month period due to window 8 normal update.

After installing win8 required updates that window indicated that are need to install.. I went ahead and do so and win as usual will ask for you to reboot.. which I did so..

and that was the mistake I did to reboot window 8 logo appears and do its things behind then it goes dark as it getting ready to load login window and nothing happen after that.. a minute or two later the screen start to flash and when you move a mouse the cursor appear flashes together with the screen..

I tried to use repair mode from a installation cd still nothing seems to be fixed. first time when that happen I had to do fresh window install.. now I can't be doing..

Please help if anyone ever experience this before.

Window 8 pr0 64bit

CPU: i7

You could try this solution which involves allowing restart to fail three times in a row: Error: Windows failed to start. A recent hardware or software change might have caused the issue after you install Windows Updates. Most problems that I have seen with Windows 8 have been related to hardware.

If it is a problem with Windows Update then you could download and run a batch file to clear the update cache.
