[QUOTE="cm105bpp, post: 1309525, member: 73966"] I think the Boot Option is part of the Mac firmware, which you can erase by mistake. If you insert the OS X Install DVD and hold the OPTION key while you press the Power-on button, and keep holding the OPTION key down until the screen displays the boot options available (the DVD and some unknown hard drive in your case), you should then be able to select the Install DVD and boot it. You do have to hold the OPTION key until the spinning indicator goes away and I think the screen changes color. Can't remember the exact screen change, but you can certainly hold it down until the boot options are displayed. Once you boot into the Install and selected your language, you can go into the Disk Utility to delete the corrupted partition and start from scratch. I'm a PC user who switched to a Macbook Pro as my primary computer 3 years ago, replaced my Mac hard-drive twice. I helps to have another PC nearby while doing this so you can brose the web for help.
