Hard drive is not showing up in disk utility
The other day, my 2010 13 inch MacBook Pro suddenly froze. I thought this was nothing too important so I just manually shut it down but when I tried turning it back on again, a grey screen with a folder with a question mark (?) on it appeared instead of my main screen. I attempted many things to try to fix this. I tried putting in the Mac OS X install disk and I tried using Disk utility but when I went there, the only things that show up are the Mac OS X disk and the DVD drive, but not the Macintosh HD.
At first I thought my hard drive had crashed so I purchased a new one and installed it. But to my dismay, this new hard drive also fails to appear on Disk Utilites.
Even when I go to the installation page where it asks me to choose a disk on which to install the OS, nothing shows up.
Is there anything I could do to fix this major problem? I've searched and searched for answers and none work. Both of my hard drives are still not recognizable
My MacBook is out of the one year warranty so I'm not sure how much the apple store would charge to fix this.
I need this problem fixed soon because I start school on four days and this MacBook is crucial up my studies.
Thank you for your help and time.
MacBook Pro, 2010
