Hello eslem, for the message that you aperase, an update that went wrong, or tried to install something to make a change, and must have gone wrong installed.
Windows 8 / 8.1 no longer boot menu with F8, so I have to bring startup error.
You have the following, start the computer normally, and when it starts to boot Windows or this this error, restart the computer if desktop or turn off forcibly if it is a Notebook, do it two or three times, why is that you must take to error Windows to display the advanced boot options menu F8 old the previous Windows, just do not look the same.
At the time aperase the Windows logo with circuits turning and below says Wait, do not touch anything, you let it go forward, must show one dark blue screen saying that Windows did not start successfully, giving two options Reset or go advanced Options, I think it says that, but it must be in that line.
You click Advanced Options, and then select Troubleshooting> Advanced, then a set of options which can be tested appear:
-Restore System which will allow manual selection of a point prior to the problems
Repair of home is another, although I do not think it's a boot problem.
-Setting Boot that is the option that allow you to run the Safe Mode and see if Windows loads in that mode and restore the computer to an earlier point to problems.
Greetings;)
