Hey Gys I need youre help,

Now i want to install the OS X new, and boot from the Install DVD of OS X.
I press the key "c" and after a while the same grey screen comes and i cant do no further action.
The Windows Partiton works well.

Do you setup Firmware password protection in Mac OS X ...
It would block usage of all the startup keys, like C, N, T, D, CMD+s, CMD+Option+p+r, CMD +v, Option, and Shift, as well as booting from anything but the Hard Drive.
