Problem erasing and reinstalling MAC OS X to factory settings?

I've been following the below instructions, but when I click Restart in step 2.......my Macbook Pro shuts down, the screen goes blank, the disk starts but then nothing happens. It never restarts to give me the option to select a language. Can anyone help, as I cant get any further than step 2 below:-

1) Insert the Mac OS X installation disc into your computers optical drive (or an optical drive connected to your computer), and then double-click the Install Mac OS X icon.

2) In the Installer, click Utilities, and then click Restart.

3) When the Language Chooser appears, select your language, and then click the Continue button (looks like an arrow).

4) In the Installer, choose Utilities > Disk Utility.

5) Select your startup disk from the list on the left, and then click the Erase tab.

6) From the Format pop-up menu, select Mac OS Extended (Journaled), type a name for your disk, and then click Erase.

7) After the disk has been erased, choose Disk Utility > Quit Disk Utility, and then follow the instructions in the Mac OS X Installer to reinstall Mac OS X.

Could the OS X disc be faulty?

With the CD inserted, turn the computer on an immediately hold down the C key. You can also try holding down ALT and pick the installl DVD from the list manually.

Are you sure it is the right disk? ie: a Mac Pro disk will usually not work on a MacBook etc...

When I try the ALT option and select the CD, the screen goes white and a small spinning wheel appears, the drive is accessing the disc but after a couple of minutes the screen goes black. The drive keeps working for a minute or so and then silence. It would appear the MBP has powered down.

I then have to hold down the power key for the same process to happen again. Ejecting the disk as well seems to take numerous attempts. For info, there is nothing wrong with the MBP I just wanted to reset to factory settings.

If I go down the Disc Utility route, I only have the option to 'erase free space'. None of the other options are blacked out or available to change/select (Format, Name etc... or the Erase option)???

The OS X disc is the one that came with the MBP.

When the screen turns black, have you tried just leaving the machine for 10minutes?

Can you get hold of someone else's install CD, to see if it does the same? Failing that you could order one of these.

Disk Utility can't erase the drive, while you are running Mac OS from it.

Over 30mins, but nothing. Thanks for your help though......much appreciated. Would Apple not replace a faulty install disc?

Worth a punt, if it is still under warrnaty.

Give them a call on 020 7153 9000 or walk past the Regent Street Store with your MBP, that way they can try another set of disks there and then.

One thing you can also try a PMU reset.

Turn the computer off and remove power adapter and battery. Now hold the power button down for 8 - 10seconds. Reinsert battery and mains and try again.

Which version of OSX is installed on the MBP?

Have you installed Snow leopard and are trying to revert back to Leopard ?

No.......it came with Snow Leopard (MBP is 2 1/2 months old), and I just want to revert to a completely new install of the OS X which should be really simple.

I dont even want to save anything from my current settings. :x

If it is that new, definitely take it back to the store.
