Hallo Artie
Because the Trusty-G4 only has one disk. Yes I did check SysPrefs/Startup Disk after the last ?
It was already selected.
Am I missing something here? Sorry.
Sometimes, a computer may refuse to start up if the Startup Disk selection becomes garbled. This can happen for many reasons--if the backup battery dies, if the computer's PRAM is cleared, or (as near as I can tell) if the phase of the moon is wrong.
Usually, if this information becomes garbled, the computer will simply take a longer than normal time to start up, but sometimes it will refuse to start up altogether. So checking the Startup Disk setting is a good first step in troubleshooting a computer that refuses to boot, even if the computer only has one disk.
