i have a fujitsu laptop , and it wont load windows

Fujitsu lifebook n series

it worked one day, then the next it wouldn’t.
there were no precursers like failed start ups, or errors before any of this, it just didn’t turn on.
well it turns on but doesnt run windows. i can get into set up but thats it, this comp is brand new, but i have no warrenty on it, and it cost me alot, some one told me my hard drive failed but that the information on it was recoverable and that i needed a new hard drive???? is that right? i just dont see my harddrive failing 2 weeks after i get it. anyway some body has to have some trick i can use to use this this comp.
thanks dwk2
