I updated my Windows 7 32-bit machine, but after some restarting it doesn't even start up, i.e. it doesn't show the desktop screen. I tried to repair it using "Start up Repair" but it can't fix the problem. I also tried the following command in "system recovery options" > command prompt:
X:\Sources>bootrec /fixmbr
and
X:\Sources>bootrec /fixboot
but no changes occurred. It even doesn't go to the safe mode! Any idea on how to fix that?
