This means that either:
- The operating system is missing from the iMac's hard drive. You will need to restore your system from the grey discs that came with your Mac.
- The hard disk is damaged. In this case you will need a new hard drive. Once you or a specialist has installed it you can then restore your system using the grey discs.
