[QUOTE="pigoo3, post: 1087426, member: 56379"] It may depend on how old/new the laptop is. If the laptop never shipped with a version of OS 10.5...then that may explain why it won't boot from the CD/DVD. A second reason may be that you have a "gray-colored" CD/DVD for OS 10.5. These gray disks are model specific. If this is not the disk that came with the laptop model that you are trying to downgrade...then that's the reason why it won't boot from it. HTH, - Nick [/QUOTE]
