after shutting down computer during software update, computer won't start up

[seaofclocks]

first i'd like to say that i did search the forums for this topic but couldn't find anything that similar (maybe i'm just bad at looking)

anyway i have leopard installed on my powerbook g4. it seems as though the software update is a bit different than on tiger as it installs the software while it's restarting or something like that.

i was installing a mac os x update and it was taking forever, so i made the stupid decision of canceling the update by turning off the computer (holding down the power button)

now whenever i try to turn on the computer, it will stay at the startup screen (with the little rotating circle under the apple). i left the computer for an hour and when i came back it was still at the same startup screen

thank you for any help you can provide me with

Can you start up in Safe Mode? (restart and then hold the Shift key)

Doing a hard shut down is never a good idea, especially when you're installing an OS. You may need a boot disk or as the above poster stated start up in safe mode.

thanks for getting back to me so quickly, i tried doing the safe boot... it didn't work.

is there someway i could boot from another disc and than finish the software update?

Thank you.

Have you tried to restart in verbose mode to see where its freezing (Press Command-v when starting up).

Also try and boot from the OS X installation DVD and repair the hard drive and repair permissions.

Good Suggestions. I will communicate them to my friend (he is in Africa !) and get back with feedback.

Thank you
