Help Removing Windows from MBP

[jammin1020]

I recently acquired a barely used Macbook Pro, 17 in. The previous owner was using windows XP on it and has no original software for the computer. I am trying to install a new Mac OS but cannot get the CD drive to boot on startup. I've tried holding the C key, and some other commands but Windows always boots up. Any suggestions? Thanks

Try holding option while the dvd is in the drive when you start the computer up

I had that problem when i used boot camp. i forgot to reboot into mac os and set the startup disk to mac. just hold option.
