Can't use Install Disk to repair my MacBook Pro HD

Question

Hi,
I ran the Mac Disk Utility on my MacBook Pro's HD and I got this screen:

So I inserted the install disk so that I could boot up from the CD and run disk utility to repair my HD.
But the MacBook Pro keeps spitting out the disk. It reads other disks fine and this install disk reads on my friends computer so I know that both the MacBook Pro drive and the install disk are ok. So what could be causing my problem?
I have also tried to boot the computer from the disc holding the "C" key down, but the computer spits out the disk and boots up from the HD.
How can I repair the HD if I can't get the OS to boot from the install disk? What else can I do? Can I boot from another HD or Thumb drive? How about an iPod?
Any information would be greatly appreciated.
Bruno

Answer 1

Are you using the OS X Installer Disc One that came with your computer? To startup from the installer disc first insert the disc in the optical drive (label side up.) If the computer does not allow the disc to mount on the Desktop then either your optical drive is bad or the installer disc is damaged or is not a valid installer disc for your model.
If the disc mounts on the Desktop then restart the computer and after the chime press and hold down the "C" key until the spinning gear appears beneath the dark gray Apple logo.
If this still doesn't work then boot the computer into single-user mode by restarting and after the chime press and hold down the COMMAND-S keys until the computer starts up to a black screen with white print. At the prompt enter or paste in the following:
/sbin/fsck -yf
Press return and wait. If you receive a message that the drive required repairs, then re-run the above command line until you receive a message that says the filesystem is OK. If you have to repeat the command more than seven times without receiving a filesystem OK message, then that means the drive cannot be repaired by fsck. If you have a utility such as Disk Warrior 4.0 or TechTool Pro 4.5.2 then you can boot from their CDs and attempt to repair the drive. If either or both fail then the drive will need to be reformatted.
I highly recommend backing up.
Yes, you can boot from any external drive provided it has a bootable copy of OS X installed on it. If you have a second Mac with Firewire ports then you can connect it to the MBP via a Firewire cable. Boot the MBP into Target Disk Mode and the other computer normally. The MBP's hard drive should appear on the other computer's Desktop. You can then repair the drive using Disk Utility or other disk repair utility.
