Internal Hard Drive won't boot

[aquietlife]

I just recently bought an external hard drive for my powerbook 12" and cloned my internal hard drive to the external.

Then I erased and re-installed Tiger on the internal to start fresh.

Now my powerbook won't boot from the internal hard drive.

I'm using it right now, but I had to boot from the external, then disconnect it, to continue using the internal. Everytime I shutdown the computer, the same thing happens-it won't boot by itself.

Does anyone know what went wrong, or how I should try to fix this?
When I hold down option when booting, and select the internal drive, it eventually turns into the "prohibiting sign." I've done disk utility repair, etc, and doesn't find any problems to repair.

Please Help! Thank you so much!

I'd disconnect the external and do a clean(erase) install without the external connected.That should do it.

Thanks Peace, but yeah, I did that, and it still went to the prohibiting sign on start up.

How would I know if my hard drive failed? Would it still show up when I hold down option to boot from? And would I still be able to use the computer at all?
