I'm a newbe to the Mac system so maybe you'll understand a simple question. I have installed an external hard drive partitioned into Backup HD and Data HD. Backup HD is a full backup made with SD and is startable. BUT..... to startup in the external it was necessary to go to the "startup disk" and select the drive I wish to use for starting.

My question is this. If my iMac hard drive fails, how do I sartup into the external if I don't have access to the "startup disk" to select the drive?

Is my method of starting up correct or is there a simpler way?

Hi, Hap. You can hold down Option when powering on to get a choice of startup drives -- see "Recovering from a disaster" in the User's Guide...

Your method is correct...when you can use your startup drive. But another method exists: While booting, hold down the Option key until a screen appears which shows all your bootable drives. Select the one you want (in this case your external drive) and click the arrow. Your Mac will then boot from the chosen drive.

Thanks for the tip. I know......RTFM. Like most of us old timers, we peruse the manual and sometimes miss a LOT of basic stuff. I think I skipped the section on Disaster. Don't even want to think about it.
