I used the disk utility  (booted to the install DVD by holding down the <C> key) to partition the hard drive in my Macbook into two partitions.  Subsequent to this, I successfully installed the OS( installed it on 1st partition)  Now I want to boot to the install DVD again so I can "nuke" the hard disk and start over.  The only problem is that now, even if I hold the <C>  key down, it won't boot to the install DVD....thought I'd see if anyone has ideas.

    What happens if you hold down the "option" key?  This key will allow you to choose which disk to boot up from.

    Probably your DVD is scratched or dirty. Take a look at the reflective side of the DVD. If it has lots of finger prints carefully wipe it clean with a lint free cloth. If it is scratched get your computer's serial number and call AppleCare for a replacement.


    If the DVD appears to be in good shape you might try a lens cleaner for the optical drive.

    So it turned out the disk was dirty.  ( I should have thought of that).  I appreciate the advice.  Thanks also for pointing out what the options key does during boot.  I'm new to the MAC world and it looks like that is kind of a cool feature which allows you to pick if you want to boot to a specific device or partition.
