I did it. Just clicked power and alt then showed locked firware password. I knew it and I choosed reinstall OSX Capitan. But there is problem now, when it installing on computer OS copy of Capitan...there I got an answer OSX could not be installed on my computer. No packages were eligible for install. Contact the software manufactured for assistance. What I should do next?
It was extremely helpful, it had all the troubleshooting steps. If you don't read the instructions in the steps there is little we can do to help you. I agree with BDAqua, your HD is likely failed. Take the computer to your local independent Apple Authorized Service Provider , have it professionally diagnosed and repaired if you fee it is worth the expense.
There is Only problem now I can't install fully OSX Capitan on my computer because could not eligible..What I need to do? I remember on my IMAC I installed Capitan from internet not from app store maybe thats why I can't install it now...
There isn't was helpfull information about quastion mark. On my IMAC doesn't worked Command and button R. There was still showed quastion mark.
It sounds like a failedHard Drive, can you get a friend to install OSX on an external drive & boot bolding alt key.
