Hi there, I have an iMac and run Mountain Lion. Upon start

Resolved Question:

Hi there,
I have an iMac and run Mountain Lion. Upon start up, I am experiencing a white screen with folder and question mark flashing n it.
I have tried unplugging and plugging back in to power up with no resolution.
Have tried to install its former OSX install disk 1 holding down C where I can get to disk utility. There is the file media but no option to repair. Also it looks like the media file says it has 0 bytes when looking at its information. Have I lost my entire drive?
Should I do I reinstall of disk 1?
Thanks in advance

CompExpert :

hi,
when you have a white screen with folder and question mark meaning the system did recognize any core files to boot to osx operating system.

two things might caused your problem: corrupted osx operating system or defective hard drive.

what you can do is reinstall Mountain Lion, if the installed go through without a problem then your problem is corrupted osx operating system. now if you got an error during installation process or system didn't recognize the internal hard drive to install mac osx operating system then you have a defective hard drive and need replacement.

500GB sata 2.5" hard drive cost about $80, you can bring to apple store to have them installed it.

follow the step below to reinstall Mountain Lion 10.8:

1.


 

CompExpert :

1. power off your computer
2. power on again right away hold down command and R key, keep holding it until you see a mac osx utilities screen
3. select option to reinstall mac osx and follow the the instruction on the screen.


remember reinstall osx will not delete your data.

CompExpert :

if you try command + R and still cannot get into mac osx utilities screen to reinstall 10.8 Mountain Lion that mean the internal hard drive is defective or dead


 

CompExpert :

* hidden partition that include all the files to reinstall osx
