Commercial Leopard install on Macbook Pro

Question

I have a Macbook Pro 15". I hae a commercial copy of Leopard that I have used on several different computers. When I try and install it on the Macbook Pro it ejects the DVD during the boot up process. It mounts on the desktop and allows me to restart from the DVD. But will not allow me to run the installer.
Any ideas why this is happening?

Answer 1

Good. It would be helpful in the future to clarify that upfront and get it out of the way.
Which MBP model do you have and on the Leopard installer which Leopard version does it say is on the DVD? If the version on the installer DVD is 10.5, then if your MBP is a fairly recent model it may require 10.5.1 or 10.5.2. If so then the Leopard installer will not work. Instead you will have to use the original installer disc that came with the computer.
If the above is not relevant, then there may be a problem with the installer disc or the optical drive. See if the installer disc mounts on the Desktop and if its contents are visible. If so then you might try burning a copy of the DVD (you'll need a dual-layer DVD-R disc and the MBP must have a Superdrive that burns dual-layer discs.) Then see if you can install from the copy. Use the following procedure to duplicate the disc:
