This is a familiar question I'm sure [:I] ]'>

I have a PowerBook 160 which I know works. I downloaded OS 7.5.3 from Apple downloads (all 19 files) as I wanted to update from 7.1 to 7.5.

While the installation procedure was underway my power cable became disconnected (no battery) which interrupted the installation.

Now when i start up i get a flashing question mark in a floppy disk icon .

What should I do please?

Thank you in anticipation.
