    I cannot get my new iMac to boot from the OS/X (or DiskWarrior) CD. Another (10.6.3) Mac boots fine with both of these CDs.

    I've run Disk Utility and done a repair permissions and even started in safe mode, but none has helped...

    I can read a CD I put into the drive, but not boot from it.

    What happens is I put in (for example) the Disk Warrior CD click Reboot, hold down the "c" Key. I see the gray apple, but no swirling circle. Then the CD stops spinning. That's it. (Same with OS/X CD)

    Any ideas what this could be?

    Bad CD drive?

    Yikes!

    Please let me know what I can try.

    Thanks.

    are the discs grey in color or black, grey discs are machine specific, where as black are retail ( boots any machine )

    if there grey it will say what machine they work with on the front ;)

    The primary test is that I'm using DiskWarrior which boots fine on my wife's machine (same iMac), but not on my new one.

    I guess I have a hardware problem of some type?

    diskwarrior is a disk recovery program, why would you be booting from it? if your disk is corrupted i'd suggest getting in touch with apple, ( new iMac should still be in warranty :) )

    Right, I was just doing an initial check of the disk (no corruption expected).

    That's when, unfortunately, I found I couldn't boot from the bootable CD....

    Thanks for your reply.

    Put in an original install disk that came with that Mac and hold option key while booting and select the disk with arrow keys and press enter

    Same thing with Diskwarrior

    Which discs though? You say they boot another mac fine, did they come with that mac? Or are they black retail discs?

    you might have an older version of DiskWarrior - the new iMacs require DiskWarrior 4.2.

    Thanks HH!

    Yes, using the option key worked using the original iMac CDs. From another posting here, perhaps my 4.1.1 version of Disk Warrior won't work on my new iMac even though it works on my wife's 27" core duo (I have an i7).

    Will investigate the Disk Warrior issue, but at least I can boot from CDs.

    Phew!

    Thank you very much. :)

    Okay, good! As Dofot9 said, new iMac require 4.2, which may be because of the new i5/i7 which use different logic board etc

    Sounds good, thanks again. I'll contact the company about an upgrade.
