   • From there, you can try repairing your disk using Disk Utility or reinstalling macOS.

4. Boot from External Drive:

   • If you have a macOS installer on an external drive, connect it to your iMac.
   • Turn on your iMac and immediately press and hold the Option key until the Startup Manager appears.
   • Select the external drive with the macOS installer and see if you can boot from it.

5. Seek Professional Help:
