    Can anyone tell me if there's some secret to booting from a CD?
    I insert the CD (in this case Disc Warrior 4.1 for OS X, also happens with Drive Genius), hold down C during start up...I get the Apple logo, then the machine just shuts down and reboots - over and over if I keep the C down.
    Is there something else I need to do, or do I have an optical drive problem?
    MacBook Pro, 2.6 GHz, duo. OS X.5.5

    You can only boot from the grey restore disks if I remember correctly, someone please correct me if I'm wrong.

    is the disk clean and fairly scratch free?

    try holding down the option key at boot instead of C

    either method should work and may take a bit of time for it to load up properly, upto roughly 10 minutes for the boot up sequence to go through.

    But try option as a second resort.

    **
    also try resetting the PRAM and SMC ... could be miscommunicating somewhere , otherwise try with your install disks to see if they load up, if so maybe need to create a new DW4.1.1 disk
    otherwise try to go into system preferences and select the DVD drive as the start up drive instead.


    hope these help

    Thanks for your reply. Its a brand new disc, right out of the box. I tried all your suggestions but none work.
    The option key solution gave me the two start up disc options, but when I selected the CD, it ignored it and booted from the HD.
    The original OS X Leopard disc was recognized and the MacBook booted up from it, but I'm really wary about re-installing anything from that disc. I'm not that technical, and I just can afford to lose stuff.

    I'm not familiar with Disk Warrior but it seems clear that you must boot from Leopard OS X using the aforementioned 'c-key.'

    Just to add one note to what Blue Velvet posted, when you read the linked material if you look closely they have a link in it as to how to use DW with a system that the disk cannot boot successfully. Easy to overlook that so just wanted to mention it.

    Start up from CD

    Hi, Thomasnatal:

    I did eventually overcome the problem, but I can't really tell you how, as it was through some random, frustrated, combination of holding down certain keys on start up. I think I held the "C", the control key and the option key for quite q while through the apple logo stage etc., but I couldn't swear to it.
    The usual rookie, non-tech solution!
    Sorry I can't be of more help.

    Hello Rugbyplayer,

    Thank you for your answer. It is really a frustrating situation. I will try to press the "right keys". Wish me luck!

    Thank you again,

    Thomas

    If MacBook Pro wont start

    I had a problem where my Macbook Pro would not start. All that would happen was that it went to a grey screen with the apple in the background and the circle swirling.
    After many hours of frustration, I pressed SHIFT and COMMAND and V during the start-up and it finally worked! Pressing 'shift' and 'command' and 'v' is the equivalent to the safe boot in Mac, and it worked. I hope this helps people who cannot start up their Macbook Pros.
    Max uses cheap hardware, and I will never purchase a mac again.

    Don't worry, he's just a troll (look at the last line). He's wrong too, only the Shift key prompts Safe Mode, Command and V simply trigger Verbose mode, which allows you to see the system prompts as the computer boots (in a text-based layout).
