I can't install OSX 10.6.3 as it says HD used for Time Machine backup, I can't install OSX 10.6.3 as it says HD used for Time Machine backup

I've just received Snow Leopard disc and tried to install it but nothign is ever that easy. It says that hard drive in use for Time Machine backup so can't install. I've never used Time Machine and settings appear to confirm that. I don't want to set it to restore and lose everything and have to install it again so not sure what to do. Can anyone advise me

iMac G4, Mac OS X (10.2.x)

If your product info is correct, you can't install Snow Leopard at all. It will only work with Intel processors (Macs from 2006 onwards)
