I cannot reinstall OS X Yosemite : an error has occured while preparing installation, run setup again
OS X Yosemite 10.10
I have checked the disk for bad sectors. The OS does not start anymore, I standard get the screen with options:
- Restore from time machine
- Install OS X again (see above result)
- Search help online
- Disk tool
Is there a way to clean the whole disk and download OS X to fix a bootable CD / DVD?
