Erase & Install, then SuperDuper?

[Macworthy]

OK, got the hard drive replaced.

I found this in the .pdf file:

Similarly, if you’ve stored a bootable backup on an external FireWire drive, and your Macintosh is capable of starting up from FireWire, hold down the Option key when you start, select the FireWire drive, and use SuperDuper! to perform the restore.

I haven't done the above yet, I had already turned the imac on to make sure it was running, and it took me through the first steps of setting up language, mouse, etc. Then asked "Did I already own a Mac?" "I could transfer from another Mac."

I chose that option to see where it would take me, and it found my SD clone on the external firewire. It lists several categories in the information window when the clone is selected, Users, Applications, Settings, Other files and folders on the (named clone drive).

Does it matter which way I restore from? Can I proceed with where I am at on the imac, or should I shut down and use restart using the instructions from the SD pdf instructions?

Thanks again, Sandy
