Hi

I want to perform a clean install on my PowerBook G4. I have the original system disk OS X 10.5. If I start up from this (holding C as I do so) and then go to reinstall, it won't let me because I have since up-graded to 10.5.8.

How do I get around this? Does this mean my original system disks are now obsolete?

Thanks in anticipation of your replies.

Thats odd. Have you tried wiping your boot drive with the Disk Utility on the 10.5 disc? A simple repartitioning should work. Then just install 10.5 onto the blank partition. Does that work?

No it's because your Powerbook didn't come with 10.5 that is a restore disc for some other machine and won't work on any other model than the one it came with.

Hansr you are partly correct.

My PB came with OSX 10.3. I then bought several OS upgrades, the last one being 10.5.1. Since then I have been prompted to do several minor online upgrades, hence why I am now at 10.5.8(?).

That is why I have system disks that are older than my OS.

Hope you can still help.

Is it a retail disc you have, or is a restore disc from another computer. if its a restore disk from another computer, it probably won't work.

Again, have you tried booting from the retail disk and repartitioning the drive through Disc Utility? Doing this will remove any trace of 10.5.8 from your mac meaning the install should go ahead

When you get to the install window showing the available hd click on it and then click the options button. Choose erase and install or re install preserving users and network settings. Press OK. Press continue.

Since it's retail it should work independent of OS version if you do archive and install or erase and install. What is the explicit message you get?

Just wipe the drive and then install if you don't need any of the files in there. If you do, do an archive and install
