I just found my OS discs so thought I would do a fresh install to clean my iMac up so I have formatted the hard drive in Mac OS Journaled format and tried to install the OS.


It goes to the language screen but then on the next step it says "Alert" "This software cannot be installed on this computer".


This discs are the original grey ones I got with the iMac version 10.4.10.


Why is my iMac stopping me from installed the OS?


Appreciate any help.

iMac, Mac OS X (10.4.10)
