So I had to just turn the machine off before the install finished and now when I boot up I get the old "The 'System' file on this startup disk may be damaged. The Installer can be used to repair this disk."

I tried to create a Network Access bootable disk using this procedure: http://lowendmac.com/brierley/08pb/classic-mac-boot-floppy.html

But the machine keeps spitting the disk out and continues to display the same error message.

Help!
