OS X 10.4 or above not found - Tiger to Leopard Install

[yusavio]

Hi all,

I purchased a MacBook one week ago whicg came pre installed with Tiger. I also qualified for the £5.99 upgrade as the MacBook was purchased after 1st October. The Leopard DVD arrived today and has written on it: Mac OS X Leopard, Upgrade DVD, Version 10.5

Having been a Windows user all my life, I chose to go with a clean install. I partitioned the hard drive into a 120 GB partition for Leopard and an 30 GB partition for Windows which will be installed via BootCamp.

However I get the following message when attempting the install:

MAC OS X cannot be upgraded to v10.5 on your computer

MAC OS X v10.4 or later could not be found on your computer

Ejecting the Upgrade CD will take me to a grey screen, so Tiger is not working also.

Any ideas? possible faulty Upgrade DVD, I can try and install Tiger using the original DVD and try upgrade of Leopard from their?

Am I going about the partition for BootCamp in the correct manner?

Many Thanks

That would be best. Then use the Boot Camp assistant (already in the Utilities folder in Applications) to partition

Me too

Just got my Mac mini today, with Drop in Leopard Disc.

Connected up my Windows Keyboard and Mouse, started her up OS 10.4 was installed so I popped in the Leopard Disc and started setup.

Next we got a power cut, in the middle of the install. So power came back on, started up mini, and now I'm stuck. As it won't as it cannot find a pervious version of OS 10.4, see pic.

I was able to eject DVD, by restarting and holding down mouse button. Have popped in the OS 10.4 Disc and doing a install of that now, once that's done will begin OS 10.5 install, again!

This seems very strange of Apple to put in a block like this on CPU Drop-in Disc I don't see any advantage except to being a pain.

I had the same problem when I tried to do an upgrade (clean install) from pre-installed Panther to Tiger with upgrade DVD. I tried to to Erase and Install, but it didn't let me to do that giving a similar error message as yours. I had to install Panther first and then upgraded to Tiger with the Tiger upgrade DVD.

I guess with Upgrade DVDs, one can only upgrade NOT do a fresh install of the new OS. I could be wrong.

You can do a fresh install, after a few hours got all mine installed and working. You can do a fresh install from Mac OS 10.4, just select custom or option (can't remember exact name) on the install page and select erase and install.

Just strange that Apple would do this, and spend extra time creating a whole new batch of DVDs with this limitation.
