I have a MacBook and last night it froze for a while, so I manually shut it down. When I tried to turn it on, it went to the white screen with the folder and flashing question mark. I don't know how to fix computers at all, so I looked online and it said to put the disc in. I went to disc utility and it shows the hard drive, but it is not as bright as the install disc.. does that mean it cannot be found? What should I do? I tried to reinstall the disc to my hard drive with the option checked to keep my old settings, etc but it did not work. Any suggestions as to what I should do would be greatly appreciated. Most of my stuff is not backed up so if there is any way I can try to save it before I try to reload the hard drive would be really great.
