Recently I couldn't get my Mac (bought in April - 2009) to boot. The hard disk was quite full and honestly speaking I kept ignoring a number of warnings from OS X to 'free up some space'. I have been trying to fix it for the past month, and I have tried a lot based on information available on Internet.
The problems are:
- The startup DVD I have takes me to Disk Utility but it fails to re-install Mac OS X.
- The disk has errors and they are there even if I erased the disk completely.
fsck -fyis not able to repair the disk.
- I created bootable USB for OS X El Capitan and I used it to boot the Mac: I get to the Apple logo and the progress bar filled up as well (after 1-2 hours)... but nothing happens after that.
