need help...

[Ilker Ozupak]

when i came to office today i saw that my computer 
 was giving error that OS was missing ..
after some investigation i found that my entire disc
was empty..
not even silices are left on it.
the maschine was running a day ago when i left it.
it had crahesed at least 2 3 times due to electric
shortage 
(its only a guess maybe more or less)

the result is the fallowing errors.
any suggestions.
i had some important data on that disk.
