Can't install OSX on a Macbook with Windows XP!! alone on it

[HelpJas]

Hey,

 

I have a Macbook pro on which i have only Windows XP . I want to install OS X10.5 on it and by no means i can boot the machine from DVD.

I have tried the this below,

1. To boot on Safe mode - dint work

2. To boot in Single user mode - dint work

3. Tried to open Firmware command-option-O-F - dint work

4. Tried to boot from DVD using 'C' -Dint work

5. Clicked 'options' button on boot, it will show, windows partition and CD but when i click on CD it will get stuck

 

Is there anyway, i can boot from Mac OS x 10.5 DVD and install it on this machine?

 

Thanks.
