How to upgrade 10.3.9 to Leopard?

Hi I'm upgrading a Mac from 10.3.9 to Leopard. I've got an image of the disc... how do I go about upgrading.

The Mac in question is a desktop (please don't shut down the thread mods! ) 1.6ghz, power-pc g5, 1.25gb. I've checked the specifications for Leopard and its seems to meet them. http://www.apple.com/macosx/techspecs/

Someone else tried unsuccessfully to upgrade Leopard on the same machine before without much luck.... hoping it might be better this time.

Any tips, links, guides are much appreciated!

 

Hi, i have never done a clean install of leopard but i have some experience of bootcamping. Remember to back up your files before doing this. Insert the leopard disk in your mac. Restart your machine. click on the command button (It's between the alt button and the space bar) when the white screen appears on boot up. Select the leopard disk and click the arrow under it. The setup should begin. Follow the on screen instructions and on completion, if leopard has successfully been installed on your machine, you should see the welcome video which is pretty cool!!!

 

I think you only need a Leopard disc.
The process is very simple. Just follow the instruction.
If you have installed Windows on your machine, with OS X, it's even simpler.

 

Agreed!!! Os X is pretty easy to install. I found out when i was reading the missing manual at the university library!

 

So by you saying you have "an image of the disk", does that mean just a copy of the OS install disk, or an image from another machine that you are going to try to "ghost" to the machine running 10.3.9?

 

Thanks all for info.

What I have is the .dmg. I know the local apple store well and instead of giving me a disc they leant me a ext hard drive with the .dmg file on it. Could I just burn this to a double layer DVD and it'll work as normal?

EDIT: .dmg is the contents of install disc, I've been informed. Is this correct? More to it than that?

 

A .dmg is an image of the disc. From your 10.3.9 computer you can use Disk Utility, located in the Utilities folder in Applications, to burn it to DVD.

There are plenty of guides to upgrading to Leopard available. The primary thing to think about is whether you want to just upgrade in place or do a clean install. The installer will have an options button allowing you to choose between upgrade, archive and install (which keeps a backup of your previous OS on the HDD), and erase and install. I generally do a clean install myself. I'm actually not sure how Archive and Install works, but I don't think the backup is bootable, it just leaves your older files in case you need to copy some files back.

 

This is why I like using a bootable firewire drive for my imaging. Connect the drive to the machine, boot from the drive, load the image to the machines hard drive, reboot, all done.
