That darn reoccuring "unable to boot' question

[Dan.y]

Tried clicking on, 'Before copy repair permissions' It did it's barber pole thing and continued for 15 minutes. I decided to stop the progress. Since it appeared to freeze before finishing I tested the permissions with 'Preferental Treatment' and all was fine with no problems.

I then re-copied to the 'Western Digital' hard drive and it finished the copy ( I have to admit that in the past it said there was a problem with a couple of files. It didn't do that this time).

I tried the option key startup and the copy showed up but when I tried to start from the copy it showed the circle/. I then tried to boot from the preference panel and it booted up fine. Half way there

Any insite on why the 'Before copy check permissions' never finished?

The ultimate goal would be to boot from the 'Option' startup. Any suggestions or potential problems making the copy boot that way?

Thanks
