Cannot install Leopard on Intel Macbook

I have an Intel Macbook (2GHz, 2GB RAM, 160GB HD) with OS 10.4.11 installed, and am trying to upgrade to 10.5 with a retail version of Leopard. However, when I attempt to boot from the install disc (which I can successfully do), I cannot install Leopard because of an error message that it "cannot be installed on this machine."

Any help/advice?

Is the Leopard DVD a complete retail version (not an update)?
Is your MBP a very recent one? If you you need a very recent version of the install DVD.
Is your HD formatted/partitioned properly for Leopard (GUID, HFS+)?

You may need to backup your Tiger install (SuperDuper or CCC clone is perfect) and then do an erase and install of Leopard on a blank HD. You can always boot into Tiger (as I do) from the backup, and you can migrate from the Tiger BU to Leopard.

Same problem here I MacBook and I needed to reformat but I lost the installer disk. I tried installing Leopard that i have as a Family Pack but the version that Family Pack is earlier than the MacBook. What to do now???
