Reinstalling OS from Linux on IBook

Ok got an IBook with its original install disks. OS 9.2. It has Linux on it now and works ok with that. I want Mac OS back on it but when I try to install it tells me that it can't find the hard drive. So thinking that I might have the wrong disks, ( i got it used so not positive 9.2 is correct) I got OS 10 and it does the same thing. When I get to the part that it asks 'where' do you want to install it show no disks at all except the CD drive.

Any Ideas what I need to do? As I said the disks are there and functioning because Linux is installed and works. Is there some type of Utility that I need to run to put a Mac partition back on it? That's my only idea that I can think of. If so what and where can I get it?

Thanks

 

Thank you, Thank you, Thank you. I know I had to be with the partitions not being correct. I just didn't know how to reset them. Great. It's loading now, if I have any other problems I'll post again.

Again Thanks,
