    G'day and welcome to the forums.

    Whenever using wireless equipment such as keyboard and mouse, always recommended having a USB keyboard and mouse for system installs and upgrades. Any chance you can borrow some? Any USB kb and mouse should do.

    And is your Mini an older PowerPC or Intel model? The original 2005/2006 Mimi has Open Firmware however the second model early 2006 Intel has an update version 1.1.

    Using OS X.7 or later make a bootable USB thumb drive before running Installer!

    There are none for a G4 as it uses a system called 'Open Firmware'.

    Maybe not. With the wired keyboard and mouse, pop in the Tiger DVD, boot from that, leave the Installer and go to utilities > Disk utility and run Repair Disk to see if the hard drive can be used. Format, and do a clean install.
