HELP with blinking screen

[sunshinegirl]

I was peacefully surfing the net using my iBook when it prompted me for updates. So i proceeded with the updates and when a text box asked if I wanted to do a restart for the updates to take effect, it lead me to a blue screen with a command prompt - looking text. I forgot what it said but i tried typing "halt" and the screen went: "CPU halted" and lead me back to tha same blue screen. I typed "logout" thinking that it might be a valid mac OS command but I ended up with a perpetual blinking text screen which said:

symbol not found: dyid_lazy_symbol_binding_entry_point
referenced from:/user/lib/libncurses.5.4.dylib
expected in: /user/lib/libncurses.5.4.dylib

I tried to do a reset, which to no avail... didn't change a single thing.

can somebody please tell me what to do??

This means that a file or lib has been corrupted, or deleted and cannot be found, thus halting a system file from running.

Best thing to do is to do an Archive and Install, making sure to preserve user/network settings so that none of your files/settings will be gone.

Sorry if this may sound a bit dumb-dumb.. but how will I do that? From the blinking screen, there's practically nothing I can do from there.. It just doesnt navigate away from it...

Insert your OS X install CD, reboot and hold the 'C' key. This will enable you to boot to the CD and perform the archive and install.
