hi i started my i mac and then... i had a black screen and under the apple logo was a gray load bar
when that load bar got to 50% my mac shuts DOWN
started the diagnostics but it said there is no problem
i tried holding the following on the startup sound but nothing changed :

well is there a way to unlock IT
please help
thanks for any HELP

Maybe I don't understand when you say "the desk is locked". The page I linked to has a picture of a screen with a padlock on it, is that what you're seeing?
so the problem is in the System folder
so what should i do to the System folder
can i reinstall it
help plz
To reinstall OS X restart while holding the Command-R keys to access the recovery partition. Choose reinstall OS X. You should have a complete backup of your system before proceeding just in case something goes wrong.
just tell me is there a chance of losing my files
or not
or 100%
and if there is a chance
tell me how to backup without going in to my files
There is always a chance of losing your files, in fact if you don't already have a backup you're taking that chance every day. Since your Mac won't start the only way I know of to back up your files is to start it up in Target Disk Mode How to use and troubleshoot FireWire target disk mode - Apple Support and connect it to another Mac and use Disk Utility or a third party app like Carbon Copy Cloner to make a bootable clone of your internal hard drive. If you do not have another Mac available or your Mac won't boot into TDM then I don't know how you would back it up.
I will add that while I've always had a backup before upgrading or reinstalling OS X nothing has ever gone wrong for me, I've been fortunate enough to have never lost files.
