Can't install OS X onto internal hard drive iMac G4

Hi everyone, sorry if this isn't the right place to post this but I'm having a problem with my iMac g4.

I bought it cheap and installed Ubuntu on it, but (idiotically) when I installed it i completely reformatted the internal hard drive. Now I'm trying to install osx again through the grey software restore disks but it can't recognize the hard drive. I've managed to use gparted on a livecd to remove the Linux partition so now the hard drive is completely blank and now I have no idea what to do.

Any help would be very much appreciated.

Cheers.

The problem is now there is no os on there, I just get the question mark folder

Sweet, thank you so much. I can't send you a message yet since I'm a new member but I will ASAP. Also thanks to you MisterKeeks for your reply. I'm excited to see if this works.
